DVP-ES3 Series Programming Manual The diagram of switching to PID_MAN / MOUT_AUTO: PID_MAN PID Calculation FALSE MV Manual input MOUT TRUE TRUE MOUT_AUTO FALSE 1. When switching the control mode (PID_MAN=0) from automatic to manual, you can set the flag MOUT_AUTO to 1 and the output value of MOUT goes along with the output value of MV. After switching to the manual mode (PID_MAN=1) , you can set the MOUT_AUTO to 0. 2. When PID_RUN changes from TRUE to FALSE, the PLC resets the value in MV to 0. When the value in MV is to be retained, you can set EN to FALSE to dismiss the instruction and to keep the output value in MV. Example 1 1. Set all parameters before executing this instruction. 2.
When M0 is ON, the instruction is executed. When PID_RUN is ON, the instruction applies the DPID algorithm. _6 When PIC_RUN is OFF, MV is 0, and store the value in MV. When M0 switches to OFF, the instruction is not executed, and the previous data is unchanged. 6-206
