PURPOSE:To display logical operation results at the point in time of monitoring with fidelity, by storing the contents of a bit accumulator in a shift register at every time when arithmetic is performed. CONSTITUTION:The output of a process input equipment 4 is processed by an arithmetic circuit 6 and the result is outputted to a process output equipment 8. Every time when the contents of a bit accumulator 7 are processed, the result is stored in a shift register 10. Once a monitoring command is accepted gy interruption, the contents of the shift register 10 at the specified point in time are displayed on a display device 9. |
