1)Initial Settings

(1)PID control module

A)Specifying used loop : loop 0

B)Specifying forward/reverse action : forward action

C)Setting SV: 12800

D)Specifying auto/manual processing : auto processing

(2)A/D conversion module

A)Specifying used channel: channel 0

B)Specifying output data type: -192 to 16191

C)Setting filter constant: 50

(3)D/A conversion module

A)Specifying used channel: channel 0

B)Specifying input data type: -192 to 16191

C)Output when no channel is used or the CPU module is in the stop state : The median value of the output range is output.

2)Descriptions of the Program

(1)A temperature 0 to 200° C from the temperature sensor is converted into an analog signal 4 to 20 mA and then the signal is input to the channel 0 of the A/D conversion module channel and converted into a digital value 9600 to 16000.
