Abstract

PURPOSE:To enable the trace of control program, by inhibiting the write-in to the file, when the address instruction is executed or external trigger signal is produced. CONSTITUTION:In checking the execution of specific address instruction by control program, the designation switch of control panel is set to the instruction address. If instruction is executed, an output appears at the coincidence circuit 24 and it is displayed on the display device 29. In this case, if the instruction of CPU2 resets the inhibition circuit 22, the career of the control program can be known. Further, in case of abnormal operation, suitable signal produced is fed to the trigger circuit 25, allowing to take the execution career of the control program.
