Dear Expert, Here we are using WinCC 7.0. Now we want to display ON/OFF (diagnostic) condition of IM153-2 [2ns] modules. How we can use OB122 in plc logic to identify which IM module was in fault or in ON/OFF mode by using its profibus ID. File atached as follows [Kindly inform if file unable to open]. Thanks to you in Advance.

In addition to what have been mentioned by MarcJan, You can ceheck the following link for 3 possible option to detect failure of slave.There are better system functions and also a WINCC Add-on to perform the task.They work much better compared to error OBs:
How do you run diagnostics on a PCS 7 / WinCC Operator Station for all the PROFIBUS DP/PA slaves connected? // I guess this is what MarcJan wants to add " I wanna know when DP Slave has a failure - OB86" |

Hi, Systemdiagnostics is a good possibility to show diagnosis in WinCC. Wüstenräuber |
