To the unit 113. The higher-level communication control processing unit 113 to which the message has been passed mainly performs communication processing relating to communication layers 4 to 7, analyzes the control content of the message, etc. Processing such as notifying the control processing unit 114 to that effect is performed.

  If the contents of the message analyzed by the higher-level communication control processing unit 113 is a reset request, the reset processing unit 115 is notified of the fact, and the reset processing unit 115 and the lower-level communication control processing unit 112 Initial processing of the device A 101 including the communication control processing unit 113 and the device control processing unit 114 is performed.

  A processing sequence when the reset control is performed is shown mainly in FIG. Upon receiving the reset control request message (121) from another device on the network, the higher-level communication processing unit 113 sends back a message indicating that it has been received (122). Thereafter, the lower-level communication processing unit 112, the device control processing unit 114, and the higher-level communication processing unit 113 perform reset processing all at once through the reset processing unit 115 (123).

It was necessary to carry out the setting again.

(1) When a malfunction in lower-order communication is detected and it is desired to perform initial processing only for the lower order. For example, when a lower address is doubled and given, only the lower order address is given again. For example, when an error has occurred in a lower-level communication medium and it has been resolved, but you want to return each state to its initial state.

(2) When a malfunction in upper communication is detected and only initial processing is desired. For example, when an upper address is doubled and given, only the upper address is given again. For example, when a mismatch occurs between devices associated with a higher-level state, and it is desired to re-associate the related devices by returning the state to the initial state.

Further, as described in Patent Document 1, when an abnormality occurs in a device, the device can be reset without preparing a specific reset signal line, and includes serial communication means. Although the configuration is adopted, this is not to reset by specifying the details of the part to be reset, but to reset the entire system.
