The proportional control is performed if you use the PID calculate instruction and set both Integral Calculus Time (variable name: TR) and Differential Calculus Time (variable name: TD) with "0".
Sample Program
In the MAIN program, place a PID instruction, which controls proportionally.
In the INIT program, assign 0 into Integral Calculus Time (PID_Control.TR) and Differential Calculus Time (PID_Control.TD) by the MOV instruction.
