If the second operand (current value: PV) of the PID instruction is an integer constant, an error will occur in GP-Pro EX after conversion. In GP-Pro EX, an integer variable can be assigned to the second operand (current value: S2).
If you convert with an integer constant as the second operand of the PID instruction (current value: PV), please replace it with an integer variable for the second operand (current value: S2).
