Data quantities, sampling times

Number of SIMADYN D channels (low amount of net data)
Number of SIMADYN D channels (230 bytes of net data)
Max. channel length (net data)
Max. number of communication associations
The maximum number of communication associations and SIMADYN D
channels could be limited by the RAM memory size.
Fastest read/write cycle via a non-cyclic master-master association
Fastest read/write cycle via a cyclic master-slave association
Fastest information report cycle via a broadcast association

General
Order No.

The SS5 communications module requires a specific processing time for
each FMS task, which must be taken into account when configuring. The
values specified in the table are nominal values for the fastest possible
sampling times, in which error-free execution can be guaranteed. For
instance, if 10 client channels are configured for master-master
communication associations, then the SIMADYN D sampling time in
which these channels are configured, should not fall below 10 x 30 ms =
300 milliseconds.
The COMSS5 configuring tool with firmware and the PROFIBUS PC
plug-in card CP5412 are required to configure the SS5 module.
COMSS5 can run on a PG under S5 DOS or with S5 DOS emulation or
COM adapter on any IBM-compatible PC under DOS.
COMSS5 provides the bus parameters and the communication
association masks for configuring, which the configuring engineer then
has to complete. The "database" is loaded into the EEPROM of the SS5
communications module via PROFIBUS when configuring has been
completed.
