Configuring the SS52 communications module with
COM PROFIBUS
If the SS52 communications module is inserted at one of the three slots
of the CS7 (currently: X01) and was configured, then values are
transferred between the transmit- or receive blocks and the bus
connector on the SS52 communications module. As SIMADYN D is a
freely-configurable system, the following logical communication structures
must be assigned:
•
Bus parameters defined (baud rate, ...)
•
The communication associations between the nodes defined (who
communicates with whom, and in which function?)
•
The communication objects must be defined
(communication objects are useful (net) data. For SIMADYN D they
consist of the process- and device data. However, for the typical
configuration, communications only involves the process data.)
This data (in the following, designated as COM database) is saved on the
SS52 in a permanently integrated memory and are changed and adapted
by downloading via the 9-pin sub-D connector of the module.
3.5.3.10
Generating the COM database with COM PROFIBUS
Master and slaves of a bus structure are configured using a graphic user
interface and a list of communication partners which are supported..
At the start, all communication associations of the typical configuration
are defined by selecting the nodes involved.
1. After the program start, the first master system is set-up using the
menu command
File > New
.

Dialog box, "Master-host selection"
2. After buffering the data (
File > Save under...
) using any name
(current: "Typical" ), a first host system is generated with the name
"Mastersystem <1>". The code number (current: 1) is identical with the
selected PROFIBUS address. This first step defines who has the “say“
on this host system.
