Interface IF1 and IF2
The CU320-2 Control Unit can communicate via two different interfaces (IF1 and IF2).
Both interfaces can be allocated the following physical interfaces:
● (1) On-board X126 PROFIBUS/X150 PROFINET
● (2) Communication Board X1400
Note
Ethernet interface X127 is intended for commissioning and diagnostics.
Do not use this interface for other purposes (e.g. field bus communication) and ensure that
X127 (e.g. for service) is always accessible.
