Terminal assignment of the sensor connections .
NOTICE
When connecting 2 sensors ensure that there is no galvanic connection between thesensors (e.g. caused by sensor elements that are not isolated from the thermowell).
The resulting equalizing currents distort the measurements considerably.
‣ The sensors must remain galvanically isolated from one another by connecting eachsensor separately to a transmitter. The transmitter provides sufficient galvanic isolation(> 2 kV AC) between the input and output.

PROFIBUS® PA cable specification

Cable typeTwin-core cables are recommended for connecting the measuring device to the fieldbus.
Following IEC 61158-2 (MBP), four different cable types (A, B, C, D) can be used with thefieldbus, only two of which (cable types A and B) are shielded.
• Cable types A or B are particularly preferable for new installations. Only these types havecable shielding that guarantees adequate protection from electromagnetic interference
and thus the most reliable data transfer. In the case of cable type B, several fieldbuses(same degree of protection) may be operated in one cable. No other circuits are
permissible in the same cable.
• Practical experience has shown that cable types C and D should not be used due to thelack of shielding, since the freedom from interference generally does not meet therequirements described in the standard.
The electrical data of the fieldbus cable have not been specified but determine importantcharacteristics of the design of the fieldbus, such as distances bridged, number of users,
electromagnetic compatibility, etc.

Maximum overall cable length
The maximum network expansion depends on the type of protection and the cablespecifications. The overall cable length combines the length of the main cable and thelength of all spurs (>1 m/3.28 ft). Please note the following:• The maximum permissible overall cable length depends on the cable type used.
• Type A: 1900 m (6200 ft)• Type B: 1200 m (4000 ft)• If repeaters are used, the maximum permissible cable length is doubled. A maximum of
three repeaters are permitted between user and master.
Maximum spur length
The line between the distribution box and field device is described as a spur. In the case of
non-Ex applications, the max. length of a spur depends on the number of spurs(> 1 m (3.28 ft)):

Number of field devices
In systems that meet FISCO with Ex ia types of protection, the line length is limited to max.
1000 m (3280 ft). A maximum of 32 users per segment in non-Ex areas or a maximum of
10 users in an Ex-area (Ex ia IIC) is possible. The actual number of users must be
determined during the planning stage.
Shielding and grounding
The specifications of the PROFIBUS User Organization for device installation must be
observed during installation.
Bus termination
The start and end of each fieldbus segment must always be terminated by a bus
terminator. With various junction boxes (non-Ex), the bus termination can be activated via
a switch. If this is not the case, a separate bus terminator must be installed. Please also
note the following:• In the case of a branched bus segment, the device furthest from the segment coupler
represents the end of the bus.
• If the fieldbus is extended with a repeater, then the extension must also be terminated atboth ends.

• Using the fieldbus connector (optional, available as an accessory) →  20
Risk of damage• Switch off the power supply before installing or connecting the head transmitter.
Failure to observe this may result in the destruction of parts of the electronics.
• Grounding via one of the grounding screws (terminal head, field housing) is
recommended.
• If the shielding of the fieldbus cable is grounded at more than one point in systems
without additional potential equalization, mains-frequency equalizing currents may
occur and cause damage to the cable or shielding. In such cases, the shielding of the
fieldbus cable should be grounded on one side only, i.e. it must not be connected to
the ground terminal of the housing (terminal head, field housing). The shield that is
not connected should be insulated!
• We recommend that the fieldbus not be looped using conventional cable glands. If
you replace even just one measuring device at a later date, the bus communication
will have to be interrupted.

10 mm (0.39 in).
• A shielded cable must be used for the connection.
Fieldbus connector
As an option, a fieldbus connector can be screwed into the terminal head or field housing
instead of a cable gland. Fieldbus connectors can be ordered as accessories from Endress+Hauser (→  49).
The connection technology of PROFIBUS® PA allows devices to be connected to the fieldbus
via uniform mechanical connections such as T-boxes, junction boxes etc.
This connection technology using prefabricated distribution modules and plug-in
connectors offers substantial advantages over conventional wiring:
20

Endress+Hauser

iTEMP TMT84

Electrical connection• Field devices can be removed, replaced or added at any time during normal operation.
Communication is not interrupted.
• Installation and maintenance are significantly easier.
• Existing cable infrastructures can be used and expanded instantly, e.g. whenconstructing new star distributors using 4-channel or 8-channel distribution modules.
Optionally, the device can already be ordered with a fieldbus connector. In addition,
fieldbus connectors can be ordered as spare parts from Endress+Hauser for retrofitting.
→  49.
Supply line/T-box shielding
Always use cable glands with good EMC properties, where possible with wrapround cableshielding (Iris spring). This requires minimum differences in potential, and possibly
potential equalization.
• The shielding of the PA cable may not be interrupted.
• The shielding connection must always be kept as short as possible.
Ideally, cable glands with Iris springs should be used to connect the shielding. The
shielding is connected to the T-box housing by means of the Iris spring located inside thegland. The shielding braid is located under the Iris spring. When the armored thread istightened, the Iris spring is pressed against the shielding, thereby creating a conductive
connection between the shielding and the metal housing.
A terminal box or a plug-in connection must be considered part of the shielding (Faradayshield). This is particularly true for separate boxes if they are connected to a PROFIBUS®
PA device with a plug-in cable. In this case, a metal connector must be used whereby thecable shielding is connected to the connector housing (e.g. preterminated cables).

• The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.
• The connecting cables used must have the specified external diameter (e.g. M20x1.5,
cable diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  10,  22
• The cables must loop down before they enter the cable glands ("water trap"). This meansthat any moisture that may form cannot enter the gland. Install the device in such a waythat the cable glands are not facing upwards. →  10,  22
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

Hardware settings via DIP switches

Procedure for setting the DIP switch:
1.

Open the cover of the terminal head or field housing.

2.

Remove the attached display from the head transmitter.

3.

Configure the DIP switch on the rear of the display accordingly. In general: switch to
ON = function enabled, switch to OFF = function disabled.

4.

Fit the display onto the head transmitter in the correct position. The head transmitter
accepts the settings within one second.

5.

Secure the cover back onto the terminal head or field housing.

Switching write protection on/off
Write protection is switched on and off via a DIP switch on the rear of the optional
attachable display. When write protection is active, parameters cannot be modified. A locksymbol on the display indicates that write protection is on. Write protection prevents any
write access to the parameters. Write protection remains active even when the display isremoved. To deactivate write protection, the display must be attached to the transmitterwith the DIP switch switched off (WRITE LOCK = OFF). The transmitter adopts the setting
during operation and does not need to be restarted.
Hardware locking for the TMT84 is disabled (HW_WRITE_PROTECTION = 0) as soon
as the display is removed. When the displayed is attached, the value set at the DIP
switch is updated in the device.
Turning the display
The display can be rotated 180° via the DIP switch. The DIP switch setting is saved anddisplayed via a read-only parameter (DISP_ORIENTATION) in the display transducer block.
The setting is retained when the display is removed.
Configuring the device address
Preparing the display:1.

Set the ADDR ACTIVE DIP switch to ON.

2.

Set the SW-HW DIP switch to HW.

3.

Disconnect the TMT84 from the PA bus (power off).

4.

Remove the display module from the TMT84 and set the ADDR ACTIVE DIP switch to
OFF.

5.

Connect the TMT84 to the PA bus again (power on).
 The configured address is permanently saved in the TMT84.

6.

Optionally, check the address in the PLC or attach a display with the ADDR ACTIVE
DIP switch set to OFF (the configured PA address is displayed when the display isstarted).

Please note the following:• The address must always be configured for a PROFIBUS® PA device. Valid device
addresses are in the range between 0 and 125. In a PROFIBUS® PA network, eachaddress can only be assigned once. If an address is not configured correctly, the device is
not recognized by the master. The address 126 is used for initial commissioning andservice purposes.
• All devices are delivered ex works with the address 126 and software addressing.
The hardware address is set via DIP switches 1 (1) - 7 (64). The DIP switch (SW-HW) must
be set to "HW" and the ADDR ACTIVE DIP switch to "ON" to use the configured hardware
address.
The transmitter must be restarted so that the TMT84 will adopt and save the DIP switch
settings.
Software address means that the saved bus address can be changed via a
DDLM_SLAVE_ADD message. In contrast, if a display with a valid address is fitted, thismeans that the address configured on the display is used and a DDLM_SLAVE_ADD
message is ignored.
Therefore, if the display is removed or a display is fitted with the SW/HW DIP switch set to
SW (ADDR ACTIVE DIP switch set to ON), this means that the bus address that is currently
saved can be changed again via a DDLM_SLAVE_ADD message. The currently saved bus
address is used until it is changed via a DDLM_SLAVE_ADD message. When this happens,
the bus address is changed directly on receipt of the message and does not require thedevice to be restarted.

iTEMP TMT84• Attaching the display during measuring operation
The DIP switches for the bus address are checked during operation and a configured,valid bus address (DIP switch: SW/HW set to HW; ADDR ACTIVE set to ON; bus address< 126) is saved and adopted the next time the device is restarted.
Attaching the display does not affect the bus address provided that the "ADDR ACTIVE"
DIP switch is set to OFF. If the switch is set to ON and if a valid bus address is configured(DIP switch: SW/HW to HW; ADDR ACTIVE to ON; bus address < 126), the address is
adopted the next time the device is started. If the device does not start within 30
minutes of the change of bus address, this change is rejected and the device retains thelast saved address.
If the "ADDR ACTIVE" DIP switch is set to ON and the SW/HW DIP switch is set to SW,
this does not affect the bus address.
• Removing the display during operation
If the display is removed during operation, the TMT84 uses the address saved in thedevice and operation continues without restriction.
• Resetting the bus address to the default value 126
1.

Attach a display with a valid HW address (DIP switch: SW/HW to HW; ADDR ACTIVE
to ON; bus address < 126).

2.

Wait until the company logo appears on the display.

3.

Remove the display and set the SW/HW DIP switch to SW.

4.

Attach the display again and wait until the company logo appears.

System integration

The device is ready for system integration after commissioning using the class 2 master. In
order to integrate the field devices into the bus system, the PROFIBUS® PA system needs a
description of the device parameters, such as output data, input data, data format, data
volume and supported transmission rate.
These data are stored in a device master file (GSD file), which is made available to the
PROFIBUS® PA master during commissioning of the communication system.
In addition device bitmaps, which appear as icons in the network structure, can also be
integrated. With the Profile 3.02 device master file (GSD) it is possible to exchange fielddevices made by different manufacturers without having to reconfigure. Generally, twodifferent GSD versions are possible using the Profile 3.02 (factory setting: manufacturerspecific GSD):• Manufacturer-specific GSD:
This GSD ensures the complete and unrestricted functionality of the field device. Devicespecific process parameters and functions are therefore available.

Before configuring, it is essential to decide which GSD should be used to operate thesystem. The setting can be changed with a Class 2 master. The TMT84 headtransmitter supports the following GSD files (see the table under → Section 6.5"Current device description files" →  28).
Every device is assigned an identification number (ID) by the PROFIBUS User Organization(PNO). The name of the GSD file is derived from this number. For Endress+Hauser, this ID
number begins with the manufacturer ID 15xx. For better classification and clarity,
Endress+Hauser GSD names are as follows:
EH0215xx

EH = Endress+Hauser
02 = GSD revision
15xx = ID No.

The GSD files for all Endress+Hauser devices can be requested as follows:

Working with the GSD files

The GSD files must be integrated into the automation system. Depending on the firmware/
software used, the GSD files can be either copied to the specific program directory or
imported into the database using an import function in the configuration software.
Example:The subdirectory is …\ siemens \ step7 \ s7data \ gsd for the Siemens STEP 7 configuration
software from Siemens PLC S7-300 / 400.
The GSD files also include bitmap files. These bitmap files are required to illustrate themeasuring points. The bitmap files must be loaded into the directory …\ siemens \ step7 \s7data \ nsbmp.
For other configuration software programs, please ask the PLC vendor for the name of thecorrect directory.

7.4

Compatibility with previous TMT184 model

If the device is replaced, the iTEMP TMT84 head transmitter guarantees the compatibilityof the cyclic data with the previous iTEMP TMT184 model with Profile Version 3.0 (ID No.
1523). It is possible to replace an iTEMP TMT184 with an iTEMP TMT84 without theneed to reconfigure the PROFIBUS® DP/PA network in the automation system even though
the devices have different names and ident numbers.
Automatic identification
Once the head transmitter is replaced, the device switches automatically from the standard
operating mode to the compatibility mode if the PROFIBUS Ident Number Selector
parameter is set to 127 (default factory setting). The compatibility mode can also be
activated by setting the PROFIBUS Ident Number Selector parameter to 128 (Manuf.
specific Ident Number 1523 - TMT184). This value is transmitted and evaluated by themaster when cyclic communication is being established. This number determines whether
the iTEMP TMT84 is configured for the standard mode or the compatibility mode.
Manual changeover from operation as an iTEMP TMT84 or iTEMP TMT184 is supported.

iTEMP TMT84• If the iTEMP TMT84 is acyclically configured via an operating program (Class 2 master),access is directly via the block structure or the parameters of the device.
• If parameters have been changed in the device to be replaced (iTEMP TMT184,
parameter setting no longer corresponds to the original factory default setting), theseparameters must be changed accordingly in the new replacement iTEMP TMT84 using
an operating program (Class 2 master).
• As the iTEMP TMT84 behaves the same as an iTEMP TMT184 in compatibility modewith regard to diagnostics and status handling, only the PA-Profile 3.0 is supported withregard to the diagnostic bits and status codes during operation in this mode.

Cyclic data exchange

In PROFIBUS® PA the analog values are cyclically transmitted to the automation system indata blocks of 5 bytes. The measured value is represented in the first 4 bytes in the form offloating point numbers in accordance with the IEEE 754 standard (see IEEE floating point
number). The 5th byte contains status information relating to the measured value. This
information is implemented according to the Profile 3.02 1)) specification. The status isshown as a symbol on the device display, if available. An exact description of the datatypes is provided in Section 11 "Operation using PROFIBUS® PA".

Endress+Hauser

iTEMP TMT84

System integration

1.

The field devices to be configured (iTEMP TMT84) are integrated in theconfiguration program of the automation system via the PROFIBUS® DP network
using the GSD file. Any measured variables that are required can be configured
offline with the configuration software.

2.

The user program of the automation system should now be programmed. The input
and output data are controlled in the user program and the location of the measured
variables is specified so that they can be processed further.

3.

An additional measured value conversion component may need to be used for an
automation system that does not support the IEEE-754 floating point number
format.

4.

Depending on the data processing method in the automation system (little-endian or
big-endian format) it may be necessary to change the byte order (byte swapping).

5.

Once the configuration has been completed, it is transferred to the automation
system as a binary file.

6.

The system can now be started. The automation system establishes a connection to
the configured devices. The process-related device parameters can now be configured
using a Class 2 master, e.g. with the help of FieldCare.

7.6

Acyclic data exchange

Acyclic data exchange is used to transfer parameters during commissioning, maintenanceor to display additional measured variables that are not contained in cyclic data
communication. Parameters for identification, control or adjustment can therefore bechanged in the various blocks (Physical Block, Transducer Block, Function Block) while thedevice is engaged in cyclic data exchange with a PLC.
The device supports the following basic types of acyclic data transfer:
MS2AC communication with 2 available SAPs.
There are two types of acyclic communication:

7.6.1

Acyclic communication with a Class 2 master (MS2AC)

MS2AC refers to acyclic communication between a field device and a Class 2 master (e.g.
Fieldcare, PDM, etc.). Here, the master opens a communication channel via a service accesspoint (SAP) to access the device.
All parameters to be exchanged with a device via PROFIBUS® must be communicated to a
Class 2 master. This assignment is done either in a device description (DD), a DTM (device
type manager) or within a software component in the master via slot and index addressing
for each individual parameter.
The slot and index, length specifications (bytes) and the data record are transferred inaddition to the field device address when parameters are written using a Class 2 master.
The slave acknowledges this write request on completion. The blocks can be accessed witha Class 2 master. The parameters that can be used in the Endress+Hauser operating
program (FieldCare) are listed in the tables in Section 13.
Please note the following for MS2AC communication:• As explained above, a Class 2 master accesses a device via special SAPs. Therefore, thenumber of Class 2 masters that can communicate simultaneously with a device is limited
to the number of SAPs made available for this communication.
• The use of a Class 2 master increases the cycle time of the bus system. This must be
taken into account when programming the controller or the control system used.

Endress+Hauser

35

System integration

iTEMP TMT84

7.6.2

Acyclic communication with a Class 1 master (MS1AC)

In the case of MS1AC, a cyclic master, which is already reading the cyclic data from thedevice or writing the data to the device, opens the communication channel via the SAP
0x33 (special service access point for MS1AC). It can then acyclically read or write (ifsupported) a parameter like a Class 2 master via the slot and the index.
Please note the following for MS1AC communication:• Currently, there are not many PROFIBUS masters on the market that support this kind ofcommunication.
• Not all PROFIBUS devices support MS1AC.
• In the user program, it is important to note that constant writing of parameters (e.g.
with every program cycle) can significantly reduce the operating life of a device.
Parameters written acyclically are saved as persistent data to the memory modules (e.g.
EEPROM, Flash, etc.). These memory modules are only designed for a limited number ofwrites. During standard operation without MS1AC (during configuration), the number ofwrite operations will not come close to reaching this limit. Incorrect programming cancause the maximum limit to be reached quickly, however, thereby significantly
shortening the life of a device.
The device supports MS2AC communication with 2 available SAPs. MS1AC
communication is supported by the device. The memory module is designed for 106 writes.

Status messages

The device displays warnings or alarms as status messages. If errors occur duringcommissioning or measuring operation, these errors are displayed immediately. Errors are
displayed in the configuration program via the parameter in the Physical Block or on theattached display. A distinction is made here between the following 4 status categories:
Status category

Description

Error category

F

Fault detected ('Failure')

ALARM function group

M

Maintenance required ('Maintenance')C

Device is in the service mode (check) ('Service mode')

S

Specifications not observed ('Out of specification')

WARNINGWARNING error category:With "M", "C" and "S" status messages, the device tries to continue measuring (uncertain
measurement!). If a display unit is attached, the display alternates between the status andthe primary measured value indicated by the relevant letter plus the defined error number.
ALARM error category:The device does not continue measuring with the "F" status message. If a display unit is
attached, the display alternates between the status message and "- - - -" (no valid measured
value available). Depending on the setting of the Fail Safe Type parameter (FSAFE_TYPE),
the last valid measured value, the incorrect measured value or the value configured under
Fail Safe Value (FSAFE_VALUE) is transmitted via the fieldbus with the status "BAD" or"UNCERTAIN" for the measured value. The fault state is displayed in the form of the letter"F" plus a defined number.
In both instances, the system outputs the sensor that generates the status, e.g. "C1", "C2". If
the name of a sensor is not displayed, the status message does not refer to a sensor but
refers to the device itself.

Corrosion monitoring

Sensor connection cable corrosion can lead to false measured value readings. Therefore
the unit offers the possibility of detecting corrosion before a measured value is affected.
Corrosion monitoring is only possible for RTDs with a 4-wire connection andthermocouples.
2 different levels can be selected in the CORROSION_DETECTION parameter (see Section11) depending on the application requirements:• Off (No corrosion monitoring)• On (Warning is displayed before the alarm value is reached - see table below. This allows
preventive maintenance/troubleshooting to be performed. An alarm message isdisplayed after the alarm limit is reached.)
The following table describes how the device behaves when the resistance in a sensor
connection cable changes, depending on whether on or off is selected for the parameter.

The sensor resistance can affect the resistance data in the table. If all the sensor
connection cable resistances are increased at the same time, the values given in the table
are halved.
The corrosion detection system presumes that this is a slow process with a continuous
increase in the resistance.

If the TMT84 is operating in compatibility mode, the device reports the manufacturerspecific ID No.: 1523 (hex) - TMT184 during cyclic data transfer.
Brief description of theblocksPhysical Block
The Physical Block contains all the data that clearly identify and distinguish the device. It
is like an electronic version of the device nameplate. In addition to parameters that areneeded to operate the device on the fieldbus, the Physical Block makes information
available, such as the order code, device ID, hardware revision, software revision, device
release, etc. The Physical Block can also be used to configure the display.
Transducer Block "Sensor 1" and "Sensor 2"
The Transducer Blocks of the head transmitter contain all the measurement-specific anddevice-specific parameters which are relevant for the measurement of the input variables.
Analog Input (AI)In the AI function block, the process variables from the Transducer Blocks are prepared for
subsequent automation functions in the control system (e.g. scaling, limit value
processing).

Sensor-transmitter-matching
RTD sensors are one of the most linear temperature measuring elements. Nevertheless,the output must be linearized. To significantly improve temperature measurement
accuracy, the device allows the use of two methods:• Callendar-Van Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van-Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter inorder to improve the accuracy of the measuring system. The coefficients for a standard
sensor are specified in IEC 751. If no standard sensor is available or if greater accuracy isrequired, the coefficients for each sensor can be determined specifically with the aid ofsensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistancethermometers (RTD). The exact values of the coefficients derive from the calibration
data and are specific to each sensor. The sensor-specific coefficients are then sent to thetransmitter.
Sensor-transmitter-matching using one of the methods explained above significantly
improves the temperature measurement accuracy of the entire system. This is because thetransmitter uses the specific data pertaining to the connected sensor to calculate themeasured temperature, instead of using the standardized sensor curve data.

The operation is geared towards the user role of the operator and groups the operating
parameters into appropriate operating menus.
Two setup modes are available in this user-oriented operating system: The "Standard" setup
and the "Expert" setup.
All the basic settings that are needed to operate the device can be made in the "Standard"
setup mode.
The "Expert" setup is reserved for experienced users or service staff. All the configuration
options of the "Standard" setup are available in the "Expert" setup mode. In addition, it ispossible to make special device settings in this mode with additional parameters. Besides
these two main menu items, the Display/Operation menu is available for configuring theoptional display and the Diagnostics menu is available for system and diagnostics
information.
The device parameters are explained in the following section using the user-oriented

Corrosion monitoring
Sensor connection cable corrosion can lead to false measured value readings. Therefore
the unit offers the possibility of recognizing any corrosion before a measured value isaffected. Corrosion monitoring is only possible for RTDs with a 4-wire connection andthermocouples.
Sensor drift detection
If two sensors are connected and the measured values differ by a specified value, an error
or a maintenance prompt (sensor drift detection) is sent to the distributed control system.
The drift detection function can be used to verify the correctness of the measured values
and for mutual monitoring of the connected sensors.
The drift detection can be activated with the Measuring type parameter. A distinction ismade between two specific modes. For the measuring type PV =(|SV1-SV2|) if PV <sensor drift detection limit value, a status message is output if the limit value isundershot or, in the case of PV =(|SV1-SV2|) if PV> sensor drift detection limit value,
if the limit value is overshot.
Procedure for configuring drift detection for sensor 1:
1. Start▾
2. Select measure type PV =ABS(SV1-SV|) if PV < sensor drift detection limit value or PV =ABS(SV1-SV2) if
PV > sensor drift detection limit value▾
3. Set sensor drift detection limit value 1 to the desired value.
▾
4. Where necessary, set the sensor drift detection to Warning or Failure.

this parameter can result in an erratic

affect subsequent control loops.

Submenus "Analog Input 1" to "Analog Input 4"
The standard parameters for the "Security settings" menu can be found in the submenu
Setup → Advanced setup →  73. The expert parameters are listed in the following table.
Status of the Output value
The status of the Output value parameter group communicates the status of the Analog
Input function block and the validity of the Output value to the downstream function
blocks.
Status of the OUT output value:

Meaning of the output value:

GOOD NON CASCADE→ OUT is valid and can be used for further processing.

UNCERTAIN→ OUT can only be used for further processing to a limited extent.

BAD→ OUT is not valid.

BAD status value occurs when the Analog Input function block is switched to the OOS mode The(out-of-service) or in the event of serious errors (see status code and system/process error messages,→  42).

Simulation of input/output
It is possible to simulate the input and output of the function block via various parametersof the Analog Input 1-4 menus:• Simulating the input of the Analog Input function block:
The input value (measured value and status) can be specified by means of the "AI
Simulation / AI Simulation value / AI Simulation status" parameters. Since thesimulation value runs through the entire function block, all the parameter settings of theblock can be checked.
• Simulating the output of the Analog Input function block:Set the operating mode to MAN with the Actual mode (→  69) parameter anddirectly specify the desired output value in the Output value (→  88) parameter.
Failsafe mode

iTEMP TMT84

Operation using PROFIBUS® PA

If an input or simulation value has the status BAD, the Analog Input function block uses
the failsafe mode defined in the "Failsafe mode" parameter. The following options areavailable in the "Failsafe mode; →  88" parameter:
Options in the FAILSAFE TYPE
parameter (failsafe mode):

Failsafe mode:

FSAFE VALUE

The value specified in the "Failsafe default value" parameter is used forfurther processing.

LAST GOOD VALUE

The last good value is used for further processing.

WRONG VALUE

The current value is used for further processing, despite the BAD
status.

 The factory setting is WRONG VALUE.
Failsafe mode is also activated if the Analog Input function block is set to the "OUT OFSERVICE" operating mode.
Limit values
The user can set two warning limits and two alarm limits to monitor the process. The
status of the measured value and the parameters of the limit value alarms are indicative of
the measured value's situation. It is also possible to define an alarm hysteresis in order toavoid frequent changes of the limit value flags and frequent switching between active andinactive alarm settings (see →  88).
The limit values are based on the output value OUT. If the output value OUT exceeds orundershoots the defined limit values, an alarm is sent to the automation system via thelimit value process alarms.
Process alarms provide information about certain block statuses and block events. The
following process alarms can be defined and generated in the Analog Input function block:
HI HI LIM

→  88

LO LO LIM

→  88HI LIM→  88LO LIM→  88Limit value process alarms
If a limit value is infringed, the priority specified for the limit value alarm is checked before
the limit value violation is communicated to the fieldbus host system.
Rescaling the input value
In the Analog Input function block, the input value or input range can be scaled according
to the automation requirements.
Example:• The system unit in the Transducer Block is °C.
• The sensor measuring range is -200 to 850°C.
• The process-relevant measuring range is 0 to 200°C.
• The output range to the process control system should be 0 to 100%.
The measured value from the Transducer Block (input value) is rescaled linearly via the
input scaling PV SCALE to the desired output range OUT SCALE:

Static Revision No.

Read

A block operates static parameters (Static attribute) thatare not changed by the process. Static parameters, whose
values change during optimization or configuration, cause
the ST REV parameter to increase by 1. This supports
parameter version management. If several parameterschange within a very short time, e.g. due to loading ofparameters from FieldCare, PDM, etc. in the device, thestatic revision counter can show a higher value. Thiscounter can never be reset and is not reset to a default
value after a device reset. If the counter overflows,(16 bit), it starts again at 1.
