Hello Tippesh; You have identified the I/O station giving you trouble. What family is this station, ET 200S, ET 200M... or tell us the part number of the head module (IM 153-2, for example). Do any of the I/O modules have a diagnostic LED active on the front?, which module number and which LED? Assuming this is a Profibus network (you haven't mentioned it yet) that gives you unpredictable glitches, try applying the suggestions in this article: https://us.profinet.com/top-5-reasons-your-profibus-network-failed/ Hope this helps, Daniel Chartier |

Hello Thippesh; Read this thread from the beginning once more, you will see there are 2 mechanisms we have used to troubleshoot your problems: - diagnostic LEDs on the CPU, the interface modules (the IM 153-1) and the I/O modules in the remote rack. - the contents of the diagnostic buffer, especially the module addresses of the faulty equipment. You could also check out the online view in HWConfig, faulty stations will appear with a fault icon, clicking on that icon will open the local diagnostic buffer of the modules, containing local fault information. You have to learn to use these troubleshooting tools, and to interpret the information provided there. Chapter 23 "Diagnostics" of the Programming with Step 7 manual is a very informative source you should look at. https://support.industry.siemens.com/cs/ww/en/view/45531107 Hope this helps, Daniel Chartier |
