Automation stations – Saia PCD2
In addition to the On-Board interfaces of Saia PCD2, the interface functions can also be extended in a modular way by means of the
various slots. Numerous protocols are therefore supported by the PCD2.M5xxx series. The physical bus specifications are offered for the
majority of 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 observed when using the PCD2.F2xxx interface modules:
For each PCD2 system, up to 4 PCD2.F2xxx modules (8 interfaces) can be used in slots 0…3.
The PCD2 system has a processor to look after both the application and the serial interfaces. Processing of the interface
modules requires the appropriate CPU capacity.
To determine the maximum communication capacity for each PCD2.M5 system, consult the information and examples
provided in Manual 26/856 for PCD2.M5.
