Dear Experts ,

I would like to ask you for help, how is possible to realize OV instruction with S7 1517F in F-FB ?

This instruction is not available  with S71517F , what I can use as equivalent of this instruction.

Thank you

Hello,

As it is clearly stated in the manual, the mentioned instruction is not available for S7-1500F.To produce the same result, check your inputs of calculations in range, check with limiters, to make the result predictable in range.Read more in attached file.

I hope this helps,
