3 Basic Knowledge
3.4. Communication
mode
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 2 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
3.5. Replacing
modules
The BNI PBS-... modules are upward compatible. A defective module can be
replaced with a module which has a greater or at least the same functionality.
