What version of firmware do you have in the 231-5QD30 module? If you do not have V01.00.05 then see this link to upgrade. https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&nodeid0=41886031&nav0=tree&lang=en&siteid=csius&aktprim=0&extranet=standard&viewreg=WW&objid=41885258&treeLang=en This should fix the problem that you are seeing. |

Have you measured TCs too see if they are floating type or they are grounded? |
