Siemens Interrupt & output - PLCS.net

Hello All,

I have S7-315-2DP w/ hardware interrupt module.

Upon entering OB40 for the interrupt, I check and input and output a solenoid.

Question is does this solenoid get updated at the end of OB40 scan or it gets updated at the end of OB1 scan?

Thanks,

End of OB1. If you want the output to update immediately, use the move QBx to PQBx method inside OB40
