stop caused by programming error ob not loaded or not possible or no frb

Post by rusiano » Thu Dec 30, 2021 4:08 pm

Hi all,
CPU S7-300.
It was fault "BCD CONVERSION ERROR".
To identify it in more detail, the OB 121 deleted.
I ended up seeing this:

"
STOP caused by programming error (OB not loaded or not possible. or no FRB)
FС number: 150
Module address: 2372
Previous operating mode: RUN
Requested operating mode: STOP (internal)......
"
I'm curious to know what the module number means in this case??

Module number 2372. This means that the module with the address 2372.
It is necessary to deal with the FC150 block, and then it will be clear in which block the BCD conversion is taking place, and why it cannot be performed.
