The checksum calculation of the iParameters (F_iPar_CRC) requires the CRC calculation program
TR_iParameter:
– Program download: www.tr-electronic.de/f/zip/TR-ECE-SW-MUL-0008
– Manual download: www.tr-electronic.de/f/TR-ECE-TI-DGB-0327
This program is a Device Tool with TCI interface (Tool Calling Interface) and can be started from
within the Engineering Tool. The network address of the measuring system to be configured is also
provided. The Device Tool enables parameterization and calculates the iPar_CRC checksum. The
checksum can either be displayed in hexadecimal or decimal form; it can be copy/pasted into the input
field F_iPar_CRC in the configuration part of the Engineering Tool.
The program can also be operated in stand-alone mode if the engineering tool does not support a TCI
interface. To do this, simply install the program under a WINDOWS operating system, load the
appropriate GSDML device description file, set the iParameter accordingly, and calculate the
iPar_CRC checksum from it.
The F_Par_CRC checksum calculation usually takes place within the Engineering Tool itself and
requires no additional software.
As with the non-safety-related application, the parameter can also be accessed after the startup phase
via the acyclic data traffic (Base Mode Parameter channel). However, for safety reasons, the
parameter is read-only.
