3-102  System- and communication configuring D7-SYS - SIMADYN D 
  Edition 12.2003 
3.7.5  Data quantities, sampling times 
  Max. number /  
max. data quantity / 
sampling time 
Number of SIMADYN D channels (low amount of net data)   Approx.100 
Number of SIMADYN D channels (230 bytes of net data)  40 
Max. channel length (net data)  230 byte 
Max. number of communication associations 
The maximum number of communication associations and SIMADYN D 
channels could be limited by the RAM memory size. 
>30 
Fastest read/write cycle via a non-cyclic master-master association  30 ms 
Fastest read/write cycle via a cyclic master-slave association  50 ms 
Fastest information report cycle via a broadcast association  30 ms 
Table 3-44  Data quantities, sampling times 
 
NOTE 
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. 
 
3.7.6 COMSS5 
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.
