6.8.3 Configuration information for integrating modules
Promass 83 is a modular PROFIBUS slave. In contrast to a compact slave, the structure of a modular
slave is variable - it consists of several individual modules. In the GSD file, the individual modules
are described with their individual properties. The modules are permanently assigned to the slots,
i.e. the sequence or arrangement of the modules must be observed when configuring the modules
(see following table). Gaps between configured modules have to be assigned the
“EMPTY_MODULE” module.
To optimise the data throughput rate of the PROFIBUS DP network, it is recommended to only
configure modules that are processed in the PROFIBUS master system.
It is essential to adhere to the following sequence/assignment when configuring the modules in the
PROFIBUS master system:
!
Note!
• The assignment of the measured variables for the Totalizer function blocks (1...3) can be changed
by means of the “CHANNEL” parameter.
• The device has to be reset once a new configuration has been loaded to the automation system.
This can be effected as follows:
–Local display
– By means of a class 2 master (e.g. Fieldcare)
– Switching supply voltage OFF and then ON again.
