DIGITAL CONTROL DEVICE AND INPUT/OUTPUT SUBSTRATE TESTING DEVICE FOR THE DIGITAL

摘要

PROBLEM TO BE SOLVED: To provide a digital control device and an input/output substrate testing device for the digital that is not influenced by a simulation signal for testing. SOLUTION: In an analog input test that confirms a precision of input of an analog input substrate 29 for inputting an analog signal from a detector and for converting it to a digital signal, a signal value for control is held in the first analog signal register 21 as a value before the test the signal value simulated before the test is saved in the second analog signal register 22 and is made not to be used for the control.
