Wherein the abnormality checking step includes a first digital input module abnormality checking step of checking whether the first function module is abnormal with respect to the first digital input module,
Wherein the step of determining whether the first digital input module is abnormal may include comparing a first signal value output from the first digital input circuit unit of the first digital input module and a second signal value output from the second digital input circuit unit of the second digital input module provided in the second function module, A signal identity determination step of determining whether or not the second signal values output from the first and second signals are identical;
When the first signal value outputted from the first digital input circuit part and the second signal value outputted from the second digital input circuit part are different from each other, the first digital test mode operating part of the first digital input module outputs the test signal 1 digital input circuit section,
Determining whether an output value of the first digital input circuit section with respect to the test signal is in an allowable range and determining whether the output value of the first digital input circuit section is abnormal with respect to the control points of the first digital input module; A control method of an automatic control device of a full duplex system including detection.
Wherein the abnormality checking step further includes a first digital output module abnormality checking step of checking whether the first function module is abnormal with respect to the first digital output module,
Wherein the step of checking whether the first digital output module is abnormal includes a step of comparing a signal inputted to the first digital output circuit part of the first digital output module and a feedback signal outputted through the first digital output check circuit part of the first digital output module And determining whether or not the first digital output module is abnormal based on the comparison result.
Further comprising an output signal cutting step of not outputting a signal output from the first analog output module to an external control target device when there is an error in the first analog output module of the first function module,
Wherein the abnormality checking step further includes a first analog output module abnormality checking step of checking whether the first function module is abnormal with respect to the first analog output module,
Wherein the step of verifying whether the first analog output module is abnormal includes a step of comparing the signal inputted to the first analog output circuit part of the first analog output module and the feedback signal outputted through the first analog output check circuit part of the first analog output module, And determining whether or not the first analog output module is abnormal based on the comparison result.
