Communication

Process data (cyclical):
The GSD file provides different data modules for representing the sensor map:
Inputs: 1 byte
– 32 bytes
Outputs: 1 byte
– 32 bytes
Or combined input/output modules
Deterministic time behavior:
Typically 3 ms cycle time 16 bits of process data and 38.4 Kbaud transmission
rate.
Service data (diagnostics, parameters):
parallel and reactionless process data
Standard IO-
modes (SIO-
mode)
Startup parameter setting possible using communication, then
binary switching signal
