Web-based Management 2:
Diagnostics - INTERBUS

Valid from firmware release 2025.0 - for earlier firmware see Diagnostics - Local bus

The Diagnostics → INTERBUS WBM 2 page is largely self-explanatory. 

The WBM 2 supports both types of INTERBUS modules at AXC F x152 controllers: the AXC F XT IB left-side extension or the AXC F IL ADAPT right-side adapter. But users need to choose one of these modules in a local bus setup, because the Web‑based Management 2 and PLCnext Engineer are only capable of handling one INTERBUS module at a time.

Diagnostic registers

In the Diagnostic registers table you will find the Status register and the two Parameter registers.

To decode the error code, refer to the INTERBUS Diagnostics Guide:

In addition, refer to the device-specific documentation in the download area of your INTERBUS product on the Phoenix Contact website.
