PL110 software reset

I am facing an issue with PL110 that causes it to reset with random intervals. What are potential reasons for this type of behavior?

Are you using interrupt?
Are you usin C code?
Can you attach you PLC software?

Thank you for the reply. Interrupt (100ms) with software PID update is in use and it seems that problems relate to this combo. I couldn't attach the the full code put it seems this single line (on 100ms interrupt) causes the problem.

Ok,
please try this:
eliminate this line on the interrupt, and put the same line in the main code, using a timer to "scan" the code every 100mS.

Do you have some errors reported by SM1?
