2. System structure
Explanation of the system structure
The field bus module controls the complete
exchange of information between the field bus
slaves (decentral I/O modules), e.g. the valve
terminal/valve sensor terminals and the proces-
sor modules in the controller.
The field bus slaves are connected via the PRO-
FIBUS-DP interface on the module. Up to 31
field bus slaves can be connected to the inter-
face (without using repeaters/bus amplifiers). If
repeaters are used, the number of connected
valve terminals/valve sensor terminals can be in-
creased to max. 122.
