Communication interfaces of Saia PCD3.Mxxxx controllers
In addition to the interfaces that the Saia PCD3 has onboard, the interface functions can also be expanded using various slots.
Numerous protocols are therefore supported by the PCD3. For the majority of protocols, the physical bus specifications are offered
as a plug-in module. If this is not the case, the bus can be connected via an external converter.

System properties required for
PCD3.Fxxx modules:
The PCD3 system has a processor that
serves both the application and the
serial ports. To determine the maximum
communication capacity for each
PCD3.M5xx0 system, consult the infor-
mation and examples provided in
the manual 26-789 for PCD3.M5xx0.
