Reset request
1) Function
It is a reset request from the controller to DN611B. When the DN611B receives the reset request, it executes
the initialization process of the module. In addition, it is possible to erase the scan list (parameters of the
slave device connected to the network) that is saved in the non-volatile memory inside DN611B by this
request.
Normal: When the reset request is executed, the DN611B enters the standby mode waiting for the
parameter setting request. When the reset request completes normally, there is no response to
the controller. To confirm the normal completion, check that the station status (05D5H) shifts from
initialization mode to standby mode.
Error: If the request is not accepted, an error response (completion status) is returned to the controller.
