4.7 I/O
The I/O form is invoked using menu item Setup
– I/O…
. or by double clicking an I/O device in the System
Map.
An I/O device is used to communicate with hardware modules for digital input and output signals. This can
be connected to all PTCs that run a station. The PTC communicates with the I/O using a local fieldbus (of
DeviceNet type) over its CAN channel.

The maximum configuration on the local I/O bus is six nodes. Each node can have a maximum of 64
inputs and 64 outputs. However, the total amount of I/O points must not exceed 192 inputs and 192
outputs per TC.
Currently the following I/O types are supported:

VIPA DeviceNet slave IM253DN

Allen-Bradley CompactBlock I/O Modules Series B (1791D)

Beckhoff BK5210

Wago DeviceNet I/O modules 750-346
An I/O device can be added to each PTC that has a PLC, i.e. the first PTC in each station.
You can add an I/O device to a station TC using the System Map. If you have used the Set up of a new
system it is automatically added.
