For decentralized expansion, the PCD3 RIO (Remote I/O) modules can be used:
PCD3.T760 Integrated Profibus DP Slave / Profi S-Net Slave connection up to
max. 1.5 MBit/s
4 plug-in I/O cassettes
Integrated web server for diagnostics, support and comissioning
(Connection to PC via optional PCD3.K225 connector cable)tional PCD3.K225 connector cable)
The maximum number of I/Os is dependent on the controller being used:
