Abstract
When a server unit is stopped by a failure, for example, and gives no response, and a monitor timer times out, an operation panel unit is switched to a proxy server. Then, the operation panel unit transmits request messages to the other operation panel units. The other operation panel units perform necessary operations, such as display and input operations, in accordance with the request messages. When the server unit recovers from the failure, the operation panel unit stops the proxy server function. Again, the server unit transmits request messages to the operation panel unit and the other operation panel units.
