3.4.3 Extensions with various module holders
The PCD2.M5_ controllers can be expanded with PCD2.C2000/C1000 components,
making additional module sockets available. Up to 7 PCD2.C2000/C1000 module
holders can be connected to the PCD2.M5_ . This allows the user to attach a
maximum of 64 I/O modules, or 1023 digital inputs/outputs.
For local expansion, the PCD2 LIO (local I/O) modules can be used.
For decentralized expansion using Profibus, the PCD3 RIO (remote I/O) modules can
be used:
When selecting I/O modules, ensure that the internal 5V and +V supply is not
overloaded.
The PCD2.M5_ controllers can be expanded with PCD2.C2000/C1000, PCD3.Cxx0
or PCD2.C1x0 components, making additional module sockets available:

2) On all PCD2 units, address 255 is reserved for the watchdog. The I/Os reserved for the watchdog cannot be used,
and no analogue and H modules can be used on the sockets with base address 240
