(2)In the PID control module, 100° C (where the signal converter output is 12 mA, 12800 as a digital value.) is set as SV. With regards to P.I.D constants, the manipulated value in the BCD digital switch is set as the proportional constant when P0020 turns on, as the integral constant when POO21 turns on, and as the Derivative constant when P0022 turns on.

(3)MV, the result from PID processing is output at the channel 0 of the D/A conversion module.

(4)If P0023 turns on, initial setting of the A/D conversion module, PID control module and D/A conversion module is executed.
