CONTROL SYSTEM AND RELAY APPARATUS
First Claim
1. A control system comprising:
- an electronic circuit;
a bus interface configured to receive, via a bus, a control signal for controlling the electronic circuit, and output a signal corresponding to the received control signal to the electronic circuit;
a signal maintaining circuit configured to maintain a value of the signal to be output from the bus interface to the electronic circuit;
a reset control circuit configured to cause the signal maintaining circuit to maintain the value of the output signal to the electronic circuit, and subsequently reset the bus interface; and
a control device configured to control the electronic circuit by outputting the control signal via the bus.

Abstract
A bus interface receives, via a bus, a control signal for controlling an electronic circuit, and outputs a signal corresponding to the received control signal to the electronic circuit. A signal maintaining circuit maintains the value of the signal to be output from the bus interface to the electronic circuit in accordance with an instruction from a reset control circuit. When the bus becomes unusable due to termination of operations of the control device or the like, the reset control circuit causes the signal maintaining circuit to maintain the value of the output signal to the electronic circuit, and subsequently resets the bus interface so as to restore the bus.
