I am using the AXL E DI16 (2701516; FW2.1.0.1) in a project and get some profinet warnings that are triggering the SF LED on the controller (AXC F 2152; FW2020.LTS) Where do I get the information on those warnings and how can they be fixed? Peter Paul
Hi Peter Paul, Those messages ultimately come from the Profinet stack, and they are based on standard diagnostics from the Profinet specification. Those specific messages, with detail from the relevant Profinet specification: Bit 3 - “Module difference is available in case of configuration difference”, results from submodules which differ from the requested ones or have diagnosis; that are
- submodules not matching the expected configuration (wrong, missing or substituted),
- submodules, where application relation has not the ownership (superordinated locked, locked by other IO controller or locked by supervisor),
- submodules having diagnosis, maintenance or qualified information, and
- submodules which are not available due to e.g. parameter checking pending (Application Ready Pending). … so this appears to indicate a mis-match between the configured and the actual Profinet network. Bit 5 - “Neighborhood information is not available” - this was addressed in an earlier thread, and results from the use of Ethernet switches that do not support all Profinet features (like LLDP). Hope this helps. ~ Martin.
