Take a look also at FB125 "DETAIL_DP_DIAG": 387257. FB126 "PNIODiag": 26996747 Best regards, Hristo Mihalev

Getting the Status for the CPU LED Indicators bhushanst or faulty channel numberof AI module.Is there any manual to read out for? For this, you should read corresponding data record of a module by using SFC59 "RD_REC".check this manual: System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 regards
