Automation stations – Saia PCD2
In addition to the onboard interfaces of Saia PCD2, the interface functions can also be expanded in a modular way with various slots.
The PCD2.M5xxx series therefore supports numerous protocols. The physical bus specifications are available for most protocols as a
plug-in module. If this is not the case, the bus can be connected via an external converter.

System properties of PCD2.F2xxx modules
The following points must be noted when using the PCD2.F2xxx interface modules:
Up to 4 PCD2.F2xxx modules (8 interfaces) can be used in slots 0…3 for each PCD2 system.
The PCD2 system has a processor to process both the application and the serial interfaces.
Processing of the interface modules requires the appropriate CPU capacity.
Consult the information and examples provided in the Manual 26/856 for PCD2.M5
to determine the maximum communication capacity for each PCD2.M5 system.
