Hi, Mr.hdhosseiniis right, The OB 81 executes only when the error comes newly. It won't execute continusoly during the presence of the Error. Try to clear the error and recreated it, this time your logic should be executed

And there is a BATTF on my power supply card. In that case M 81.0 should be "SET", untill I "RESET" it. It is not happening. ????? Hello, Check the point here: Battery error with the S7-400: OB81 is not called
do you use S7 400H? Best regards Hamid Hosseini |

As Saravana told you earlier you need to clear the fault then retrigger it to test your logic |

Hello, Besides what mentioned, I suggest reading section related to "Operator controls and indicators " of THIS manual because "comments from experts never substitue reading manuals"! 3.1 Common characteristics of the power supply modules 3.3 Backup battery (option) 3.4 Operator controls and indicators 3.5 Fault/Error messages via LEDs Best regards Hamid Hosseini |
