Hi, What is the difference between P_TRING and |P| ladder instruction. and why I should affect a tag below the two instructions? Thanks for replies
Hi, The safety program put your cpu to STOP. The data used to calculate your outputs in the safety program changed between start and end of your safety program (OB123).

Hi,

The data used to calculate your outputs in the safety program changed between start and end of your safety program (OB123).
Please check this siemens guide:
In your error log I can see that the issue is with your %Q430.0 output.
Please check the network where your %Q430.0 output is writen. maybe the data (inputs and other data) used to calculate this output are changed in other tasks.

Hi, use P_TRIG to monitior everything in the left of this instruction. It turns to ON for one scan when the entire set of logic to the left goes from off to on use -|P| to monitor a single tag. it turns on one scan when the tag goes from off to on. Best regards
