Abstract
PURPOSE: To make easy the analysis of failure and to reduce the failure investigating time, by feeding the content of the comparison coincidence data register and the selective information register by the control program to the selective logic circuit and performing the production of coincidence condition of output of the circuit.
CONSTITUTION: The comparion and coincidence information read out with the out instruction of the control program is set to the comparison and coincidence data register 1 and also set to the designated registers 9...14, fed to the comparison circuits 15...20 and compared with the comparison objective data on the data line. Further, the comparison and concidence signals CPA...CPF are fed to the NOT circuits 23...29 of the selective logic circuit 22 to produce the comparison and coincidence condition desired from the circuit 22 together with the selection signals SLA...SLF of the control program output from the selection information register 21. Thus, trace of failure and analysis or detection of failed part can be made easy, allowing to remarkably reduce the failure investigating time.
