Programmable Logic Controller System And Computing Unit
Abstract: The programmable logic controller system (100) according to the present invention is provided with a programmable logic controller (10) that comprises: an analog output unit (12) which performs digital to analog conversion; an analog input unit (11) which performs analog to digital conversion; and a computing unit (13) provided with an analog to digital conversion diagnostic processing unit (131) which diagnoses that there is an abnormality in the analog to digital conversion function if a second digital value which is obtained by first performing digital to analog conversion on a first digital value by means of the analog output unit (12) and then performing analog to digital conversion on the resulting analog value by means of the analog input unit (11) is not identical to the first digital value. The programmable logic controller system (100) is further provided with a relay (20) which causes the analog input unit (11) to switch between receiving an analog signal from an external device (30) and receiving from the analog output unit (12) the analog value obtained by performing digital to analog conversion on the first digital value.
