Abstract
PURPOSE: To prevent the generation of an error output at the time when the power supply is put to work, by putting off the actuation of an output actuation part by the time when an arithmetic unit performs at least single write operation in an output register at the time of power feed.
CONSTITUTION: To output actuation part 5 in output unit 2 which extracts the control output of a process controller, reset signal 7 is applied from arithmetic unit 1 via delay circuit 8. After reset signal 7 is released, this delay circuit 8 delays the actuation of output unit 2 by the time when arithmetic unit 1 performs at least single write operation in output register 3. Within this delay time, arithmetic unit writes a normal output in register 3 and after the above-mentioned delay time, a normal arithmetic result is read out from register 3 under the control of output actuation part 5. Consequently, the generation of an error signal when the power supply is put to work can be prevented.
