concept of the plant! Keep the cable shield between the stripped fieldbus cable and theground terminal as short as possible! Connection of the functional grounding may beneeded for functional purposes. Compliance with the electrical codes of individual
countries is mandatory.
‣ If the shielding of the fieldbus cable is grounded at more than one point in systems
without additional potential matching, mains frequency equalizing currents can occurthat damage the cable or the shielding. In such cases, the shielding of the fieldbus cable
is to be grounded on one side only, i.e. it must not be connected to the ground terminalof the housing. The shield that is not connected should be insulated!
‣ We recommend that the fieldbus not be looped using conventional cable glands. If you
later replace even just one device, the bus communication will have to be interrupted.
• The terminals for the fieldbus connection have integrated reverse polarity
protection.
• Cable cross-section: max. 2.5 mm²• A shielded cable must be used for the connection.
Follow the general procedure. →  14.

Fieldbus connector

The connection technology of PROFIBUS® PA allows devices to be connected to thefieldbus 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:• 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. If the transmitterhas been ordered with the option of a fieldbus connector (order code → cable entry:
position A and B), the fieldbus connector is ready mounted and wired upon delivery.
Fieldbus connectors for retrofitting can be ordered from Endress+Hauser as an accessory(see the 'Accessories' section).
Supply line/T-box shielding
Always use cable glands with good EMC properties, if possible with all-round contact of
the cable shielding (Iris spring). This requires minimum differences in potential, andpossibly 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 is tightened, 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 applies, in particular, to remote boxes if these are connected to a PROFIBUS®
PA device by means of a pluggable cable. In such a case, a metal connector must be used
whereby the cable shielding is positioned at the connector housing (e.g. prefabricatedcables).

Ensuring the degree of protection

The device meets all the requirements of IP66/IP67 protection. Compliance with thefollowing points is mandatory following installation in the field or servicing in order toensure that IP66/IP67 protection is maintained:• The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.
• All housing screws and screw caps must be firmly tightened.
• 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. →  9,  19
• 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 so that thecable glands are not facing upwards. →  9,  19

Note the following points:• 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 reserved for initial commissioning andservicing.
• On leaving the factory, all devices are delivered with the default address 126 andsoftware addressing (DIP switch set to "ON").
The bus address is configured as follows:• 'Software' DIP switch set from "ON" to "OFF": The device restarts after 10 seconds andadopts the valid bus address configured with DIP switches 1 to 64. The bus address
cannot be changed by software via a DDLM_SLAVE_ADD telegram.
• 'Software' DIP switch set from "OFF" to "ON": The device restarts after 10 seconds andadopts the default bus address 126. The bus address can be changed by software via a

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 contained in a so-called device master file (GSD file), which is madeavailable to the PROFIBUS® PA master during commissioning of the communication
system.
In addition, device bitmaps, that 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
speaking two different GSD versions are possible with Profile 3.02 (factory setting:manufacturer-specific GSD):• Manufacturer-specific GSD:
This GSD ensures unrestricted functionality of the field device. Device-specific processparameters and functions are therefore available.
• Profile GSD:
Varies with regard to the number of Analog Input blocks (AI). If a system is configured
with the profile GSD, devices of different manufacturers can be exchanged. However, it isessential to ensure that the order of the cyclic process values is correct.

Ident number selector = 130
5. Profile GSD, PA139702.gsd (3 analog inputs)
Ident number = 9702 (hex)
Ident number selector = 131

Before configuring, it is essential to decide which GSD should be used to operate theplant. The setting can be changed using a Class 2 master. The TMT162 fieldtransmitter supports the following GSD files (see table under → "Overview of device
description files" section →  25).
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 starts with the manufacturer ID 15xx. For better classification and clarity of therespective GSD, 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:• Internet (Endress+Hauser) → http://www.endress.com (Downloads → Software)• Internet (PNO) → http://www.profibus.com (GSD library)• On a CD-ROM from Endress+Hauser. Please contact an Endress+Hauser sales office.

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 IEEE 754 standard (see IEEE floating point
number). The 5th byte contains status information relating to the measured value, which
is implemented as per profile 3.02 1) specification. The status is displayed as a symbol on
the device display if available. Refer to Section 11 "Operation via PROFIBUS® PA" for a
detailed description of the data types.

1.

The field devices to be configured are integrated into the configuration program of
the automation system via the PROFIBUS® DP network using the GSD file. Required
measured variables can be configured offline with the configuration software.

2.

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

iTEMP TMT162

System integration

3.

If necessary, an additional measured value conversion component must be used foran automation system that does not support the IEEE-754 floating point number
format.

4.

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

5.

Once configuration has been completed, this 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 set using aClass 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 for the display of further measured variables that are not contained in cyclic data
communication. Parameters for identification, control or adjustment can thus be changedin the various blocks (physical block, transducer block, function block) while the device isin cyclic data exchange with a PLC.
The device supports the MS2AC communication with 2 available SAPs (Service Access
Point) during acyclic data transfer.
With regard to acyclic communication, a distinction must be made between two types:

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 an SAP(Service Access Point) to access the device.
All parameters to be exchanged with a device using PROFIBUS® must be communicated toa 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, details on length (byte) and the data record are transferred in addition
to the field device address when parameters are written using a Class 2 master. The slaveacknowledges this write request on completion. The blocks can be accessed with a Class 2
master. The parameters that can be used in the E+H operating program (FieldCare) are
shown in the tables in Section 13.
Note the following for MS2AC communication:• As already explained, a Class 2 master accesses a device via special SAPs. Therefore, thenumber of Class 2 masters that can communicate simultaneously with a device will
depend on 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 control system or controller used.

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) and can then, like a Class 2 master,
acyclically read or write a parameter by means of the slot and the index (if supported).
Note the following for MS1AC communication:

Endress+Hauser

29Commissioning

iTEMP TMT162• Currently, there are few PROFIBUS masters on the market that support this kind ofcommunication.
• Not all PROFIBUS devices support MS1AC.
• In the user program, you must be aware that constant parameter writing (e.g. with every
program cycle) can drastically reduce the operating life of a device. Parameters written
acyclically are saved as persistent data to the memory modules (e.g. EEPROM, Flash).
These memory modules are only designed for a limited number of writes. This numberof writes is not even nearly reached in normal operation without MS1AC (duringconfiguration). This maximum figure can be quickly reached as a result of incorrect
programming and thus the operating time of a device can be drastically reduced.
The device supports MS2AC communication with two available SAPs. MS1AC
communication is supported by the device. The memory module is designed for 106 writes.

Commissioning

8.1

Post-installation check

Before commissioning the measuring point, make sure that all final checks have been
carried out:• "Post-mounting check" checklist• "Post-connection check" checklist
The functional data of the PROFIBUS® PA interface as per IEC 61158-2 (MBP) must
be observed.
A standard multimeter can be used to check the bus voltage of 9 to 32 V and thecurrent consumption of approx. 11 mA at the measuring device.

8.2

Switching on the device

Once you have completed the post-connection checks, switch on the supply voltage. The
transmitter performs a number of internal test functions after power-up. During thisprocess, the following sequence of messages appears on the display:
Step Display

If the switch-on procedure is not successful, the relevant diagnostic event is displayed, depending
 on
the cause. A detailed list of diagnostic events and the corresponding troubleshooting
instructions can be found in the "Diagnostics and troubleshooting" section .

The device works after approx. 18 seconds! Normal measuring mode commences as soon
as the switch-on procedure is completed. Measured values and status values appear on thedisplay.

Configure the measuring inputs (see Section 14 for detailed description)▾
Configure the Analog Input parameters (see Section 14 for detailed description)

1.

Check hardware write protection.
 The HW WRITE PROTECTION parameter shows whether write access to thedevice is possible using PROFIBUS® (acyclic data transfer, e.g. using the"FieldCare" operating program): SETUP → ADVANCED SETUP → HW WRITEPROTECTION One of the following options is displayed:- OFF (factory setting) = write access possible using PROFIBUS®
- ON = write access not possible using PROFIBUS®

2.

Disable the write protection if necessary,

3.

Enter the tag name (optional). DIAGNOSTICS → SYSTEM INFORMATION → TAG

4.

Configure the bus address. Hardware addressing using DIP switch,

5.

Configure the transducer blocks.
 The individual transducer blocks cover various settings such as unit, sensor typeetc. The parameter groups are grouped together in blocks as follows:– Temperature sensor 1 → Transducer Block 1 (Slot 1)– Temperature sensor 2 → Transducer Block 2 (Slot 2)

6.

Configure the Analog Input function blocks 1-4. The device has four analog input
function blocks (AI modules). They are used to transmit different measured variables
to the PROFIBUS® master (Class 1) cyclically. The allocation of a measured variable tothe analog input function block is shown below using the example of Analog Input
Function Block 1 (AI module, slot 1). Using the AI N CHANNEL function, you canspecify the measured variable that should be transferred cyclically to the PROFIBUS®
master (Class 1) (e.g. Primary Value Transducer 1):

7.

Call up the AI N CHANNEL function.
Select the "PV Transducer 1" option. The following settings are possible: AI N
CHANNEL (n: number of the AI block) → – Primary Value Transducer 1 – Secondary
Value 1 Transducer 1 – Reference Junction Temperature – Primary Value Transducer
2 – Secondary Value 1 Transducer 2

8.4

Protecting settings from unauthorized accessIf the device is locked against configuration, it must first be enabled via the hardware lock.
The device is write-protected if the lock symbol is shown on the display.
To unlock, switch the write protection switch located on the electronics module to the "OFF"position (hardware write protection), .
When hardware write protection is active (write protection switch set to the "ON"position), write protection cannot be disabled via the operating tool.

Overview of diagnostic information

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

Description

Error category

F

Fault detected ('Failure')

ALARM

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!). Alternating with the main measured value, the status is displayed onsite
in the form of the letter in question plus the defined error number (7-segment display).
The ’#’ symbol is also displayed.
ALARM error category:The device does not continue measuring with the "F" status message. Depending on thesetting of the Fail Safe Type parameter (FSAFE_TYPE), the last valid measured value, theincorrect measured value or the value configured under Fail Safe Value (FSAFE_VALUE) istransmitted via the fieldbus with the status "BAD" or "UNCERTAIN" for the measured value.
The display alternates between the last valid measured value and the status - indicated by
the letter "F" - plus a defined number (7-segment display) and the '#' symbol.
In both cases, the sensor which generates the status, e.g. "SENS1", "SENS2", is output on the
14-segment display. If the name of a sensor is not displayed, the status message does notrefer to a sensor but refers to the device itself.
Abbreviations for output variables:• SV1 = Secondary value 1 = Sensor value 1 in Temperature Transducer Block 1 = Sensor

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 Section
14) 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.

Significant measuring error increase for temperatures lower than 300 °C (572 °F).
When operating conditions are based on a large temperature range, the TMT162 offers the ability to split the range. For example, a Type S or R
thermocouple can be used for the lower range and a Type B can be used for the upper range. The TMT162 is then programmed to switch at apredetermined temperature. This allows for utilization of the best performance from each individual thermocouple and provides 1 output that
represents the process temperature. Note: the option for two sensor inputs must be included in the order code for the HART® protocol. Two
sensor inputs are already provided as standard if the FF and PA protocol are selected.
Basic requirements of NE 89: detection of increased wire resistance (e.g. corrosion of contacts and wires) of TC or RTD/4-wire.

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:

50

Endress+Hauser

iTEMP TMT162

Technical data

• Customized linearization
The transmitter can be programmed with sensor-specific curve data with the PC
configuration software. As soon as the sensor-specific data have been entered, thetransmitter uses these to create a customized curve.
• Callendar-Van-Dusen coefficients
The Callendar-Van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
where A, B and C are constant. They are commonly referred as Callendar-Van-Dusencoefficients. The precise values of A, B and C are derived from the calibration data for
the RTD and are specific for each RTD sensor. The process involves programming thetransmitter with the curve data for a certain RTD instead of using a standardized curve.
Sensor transmitter matching using one of the methods explained above significantly
improves the temperature measurement accuracy of the entire system. This is a result of
the transmitter using the sensor’s actual resistance vs. temperature curve data instead of
the ideal curve data.

Example of calculating the total uncertainty of measurement of a thermometer:
Ambient temperature drift Δθ = 10 K (18 °F), Pt100 Class A, measuring range
0 to +100 °C (+32 to +212 °F), maximum process temperature: 100 °C (212 °F), k = 2• Basic measured error: 0.1 K (0.18 °F)• Measured error caused by ambient temperature drift: 0.04 K (0.072 °F)• Measured error of the sensor: 0.15 K (0.27 °F) + 0.002 * 100 °C (212 °F) =0.35 K (0.63 °F)

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.

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 →  62. 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,→  35).

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 the simulation
value runs through the entire function block, all the parameter settings of the block can
be checked.
• Simulating the output of the Analog Input function block:Set the operating mode to MAN with the Current mode (→  58) parameter anddirectly specify the desired output value in the Output value (→  77) parameter.
Failsafe modeEndress+Hauser

75

Operation using PROFIBUS® PA

iTEMP TMT162

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; →  77" 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.
The failsafe behavior is only effective in the "Auto" operating mode! In the "Out ofService" operating mode, the measured value is set to NAN (Not a Number =0x7FC00000L) and the status to "Bad - Passivated" (for Profile 3.02) or to "Bad - Out
of Service" (for Profile 3.01/3.0). The limit bits are set to "Const".
• "Bad - Passivated" = 0x23
• "Bad - Out of Service" = 0x1F
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 relative situation. It is also possible to define an alarm hysteresis inorder to avoid frequent changes of the limit value flags and frequent switching between
active and inactive alarm settings (see →  77).
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

→  77

LO LO LIM

→  77

HI LIM→  77

LO LIM→  77

Limit 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 inaccordance with 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%.

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
