Introduction

Introduction

This manual describes the "iTHERM TrustSens Calibration Monitoring" functionality of the
Memograph M RSG45. This functionality is only available if one or more iTHERM
TrustSens TM37x thermometers are connected to the Memograph M RSG45 via the HART
interface.
The Memograph M RSG45 application package contains the following functions:• Up to 20 iTHERM TrustSens TM371/TM372 can be evaluated via the HART interface• If a self-calibration is detected: The related values (temperature during self-calibration,
deviation from target value, status information, etc.) are entered as an event in the
Memograph M RSG45 logbook with a time stamp
Note: This functionality is not designed to read out the internal circular buffer (350
self-calibrations) of the connected iTHERM TrustSens devices. Rather, newcalibrations now occurring are logged online, time-stamped with the RSG45 real-timeclock and saved.
• Display of self-calibration data on the Memograph M RSG45 screen or online via the
Web server• Generation of calibration history with a "Calibration ID" (number of self-calibrations
performed)• Generation of a calibration certificate as an RTF file ("Rich Text Format") directly at the
Memograph M RSG45• Evaluation, analysis and further processing of the calibration data using "Field DataManager" (FDM) analysis software• Data management, storage and handling of certificate data fully complies with therequirements of FDA 21 CFR Part 11.

Connection example: iTHERM TrustSens TM37x connected to Memograph M RSG45 via HART input cardand internal transmitter power supply.

If the power supply has been connected correctly and the measuring device is ready for
operation, the LED on the iTHERM TrustSens TM37x is lit green.
A HART Multidrop configuration is also possible but is not recommended due to theslower update rate. Up to 5 iTHERM TrustSens TM37x can be connected per HART
input using Multidrop.
For details, see the Operating Instructions BA01581T (iTHERM TrustSens) andBA01338R (Memograph M)
Both the digital HART values and the 4 to 20 mA signal can be evaluated at every input of
the Memograph M RSG45. The 4 HART values (PV, SV, TV, QV) of a sensor can beevaluated and the analog HART value (PV) can be measured via the digital HART signal.
These values can be used in the Memograph M RSG45 with the standard functions(mathematics, logging, visualization, etc.).
Note:
The number of internal data channels in the Memograph M RSG45 is limited to 40. If
all 4 HART values are read for each connected iTHERM TrustSens, a maximum of 10
iTHERM TrustSens can be connected to a Memograph M RSG45. If, on the other hand,
only 2 HART values are evaluated, a maximum of 20 iTHERM TrustSens can beconnected to a Memograph M RSG45.

Configuration of iTHERM TrustSens TM37x

To ensure that the iTHERM TrustSens TM37x can be uniquely identified, the tag name
(TAG) should be modified in the fieldbus. The factory setting is a combination of the
product root and the serial number (e.g. EH_TM371_M903FA04487).
For details on commissioning, see Operating Instructions BA01581T (iTHERM

5iTHERM TrustSens Calibration Monitoring

Configuration of the Memograph M RSG45
The DIN rail version of the Memograph M RSG45 can be configured using FieldCare ora Web server. Here it is advisable to connect the device to the PC via USB ("Ethernet
via USB", IP: 192.168.1.212).
For details, see Operating Instructions BA01338R (Memograph M)

In order to monitor the self-calibration function, the Memograph M RSG45 must read out
the sensor temperature (PV) and the number of self-calibrations (TV). For this purpose,configure the corresponding inputs under Expert → Communication → HART and assign
them to the universal inputs under (Expert → Universal input x).
Self-calibration monitoring is activated under Expert → Application → Monitor selfcalibration. It is possible to either save every self-calibration that is detected in the event
log, or the first calibration of the day.
If " First of the day" is activated, the ID number may not be consecutive if several selfcalibrations are performed in one day.

Visualization of a self-calibration (example). Note: The measured values displayed depend on the specificconfiguration. The calibration time indicated on the cursor line, coinciding with an increase in thecalibration counter and change in the calibration deviation value, is the time when the calibration process
ended.

Analysis via mathematics functions (option)

With the mathematics package, the digital HART values (PV, SV, TV, QV) of the iTHERM
TrustSens or the results of other math channels can be linked mathematically. A formulawith up to 200 characters can be created using a formula editor. Once entered, the user
can then check the plausibility of the formula.
A control input or a relay can also be switched via a limit value on a mathematics channel(e.g. to signal an alarm in the event of temperature overrange detection or calibration
deviations).
For details on the mathematics functions and error messages, see the Operating
Instructions BA01338R (Memograph M)

6.3

iTHERM TrustSens status evaluation

In addition to simply logging the self-calibrations performed by connected iTHERM
TrustSens thermometers, it is also possible to forward an evaluation of the current device
state to a PLC or control center in order to trigger warnings or actions.

The iTHERM TrustSens is connected to the 4 to 20 mA/HART inputs of the RSG45. Optionally, the
4 to 20 mA signal can also be looped to a PLC for process control. RSG45 evaluates the device status(measured value status) and outputs a message to the PLC via relay outputs or the fieldbus (optional) in
the event of a warning/error. The iTHERM TrustSens can be configured and commissioned, for example,
using the "FieldCare" PC software tool and via the Ethernet port of the RSG45 using Ethernet-to-HART
communication.

In addition to transmitting the measured value, the iTHERM TrustSens also transmits
status information with one of the following statuses via HART:• Status OK - good
• Warning - poor accuracy or manual fixed• Alarm (error) - bad
If several iTHERM TrustSens sensors are connected, the status is a "collective status" for all
the sensors. This means that as soon as an alarm-related event occurs in one of thesensors, this is detected and signaled by the RSG45 via the relay output for example. The
RSG45 does not assess which event has occurred (calibration error, error limit, alarm limit,
cable break, calibration interval, etc.). If necessary, the details regarding the events can beread out of the sensors with FieldCare (DTM).
For each event, it is possible to define how the device should behave (alarm or warning
message) in the iTHERM TrustSens. The setting affects the measured value status (seeabove) and the behavior of the current output.
For details, see Operating Instructions BA01581T (iTHERM TrustSens), Section 9.3
Diagnostics information
In addition, there are also "Status Signal" settings in which HART-specific status
messages can be defined for each event. These are needed, for example, for detailed
analysis of the health of the iTHERM TrustSens (see above).
Configuration of the diagnostic behavior (fault behavior) in the iTHERM TrustSens:"Alarm": Current output outputs an error current.
Measured value status: "bad"; RSG45 displays the error "F100". (If error F100 occurs, dashes
appear on the display in the place of all HART values. The calibration counter value isdisplayed correctly, however.)"Warning": Current output outputs the measured value.
Measured value status: "poor accuracy", RSG45 displays valid measured values and thewarning message "W960" and signals this via text, the relay output or the fieldbus output.
"Disabled": The current output outputs the last valid measured value. RSG45 displays themeasured value (otherwise no action is performed).

Operation at the Memograph M RSG45

iTHERM TrustSens Calibration Monitoring

A math channel in RSG45 is used to monitor the device status of all the iTHERM TrustSens
that are connected (the RSG45 must be ordered with the mathematics function).
The following setup example shows how the measured value statuses are monitored inchannels 1-12 for 12 connected iTHERM TrustSens:
Step 1: Configure the mathematics channel for analysis
A mathematics channel to read in the status information is created under Menu → Setup→ Advanced setup → Application → Maths:

A0051548

The formula minAI(5;1;12) returns the lowest value for input channels 1-12 and writes
the aggregate value for the device statuses of the connected iTHERM TrustSens 1-12 to
the Status_check result.
Step 2: Evaluation of the Status_check via the limit function
Two limit values for a warning and an error are created and configured under Menu →Setup → Advanced setup → Application → Limit values :16
