Installing additional (external/remote) base devices
Additional base devices can be used as external/remote I/O devices, and assembled
together in the same way as add-on devices, but they must be connected with
separate Ethernet cables. The Ethernet cable can be connected to any of the
connectors X3 or X5 on the previous base device.
The logical power supply, connector X4, of up to five base devices in total can be
connected in parallel if the devices are placed inside the same controller cabinet,
i.e. over short distances. For all other applications, the logical power must be
supplied separately to each base device.
The process power supply must always be supplied separately to each base device.
CAUTION
Connecting the process power supply in parallel or through the logical power
supply connector may damage the device.
