Abstract

PURPOSE:To immediately report the initialization completion of a controller in a remote place to a central processor equipment by sending out an initialization settin frame from the controller, as well, when the detection of an initialization completion frame from a channel is executed exceeding a prescribed time. CONSTITUTION:When the initialization of a channel 1 is completed, an initialization completion frame is sent to a remote controller 2 from a frame sending-out circuit 17. When the initialization completion frame is received continuously exceeding the time determined in advance in a detecting circuit 106, the device 2 informs it to a data transfer control circuit 105. The circuit 105 sends out the initialization completion frame to the channel 1 from a sending-out circuit 103. The channel 1 detects the initialization completion frame from the device 2, stops sending out the initialization completion frame from the circuit 17, and also, reports the initialization completion to a central processor equipment through a reporting circuit 11.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an initial setting management method for a remote control device.

[Conventional technology]

In the prior art remote control device initialization management methods, the channel periodically sends a unique frame to the remote control device and detects a unique frame in response from the remote control device, or the channel Initial settings of the remote control device were managed by waiting for a report frame indicating completion of initial settings to be transmitted from the device.

[Problem to be solved by the invention]

In the above-described conventional initial setting management method for a remote control device, the channel periodically sends a unique frame to the remote control device and manages the initial settings by detecting a unique frame in response from the remote control device. Therefore, a mechanism for periodically sending frames specific to the channel to the remote control device is required, which increases the amount of hardware in the channel.

Also, if the channel is powered up later than the initialization of the remote controller, if noise is sent on the optical fiber when the channel is powered up and that noise is a unique frame, it will send a unique response to the remote controller. Since the frame is sent out, the completion of the initial setup of the remote control device is not correctly notified.

Additionally, if the remote controller is powered up later than the channel, and as before, if the remote controller powers up and sends noise on the optical fiber and that noise is the characteristic frame of the response, the channel will erroneously This has the disadvantage that the device is notified that the initial settings of the remote control device have been completed.

Furthermore, if the method is such that the remote control device transmits an initialization completion frame after the initialization of the remote control device is completed,
There was a drawback that the power for channel measurement had to be turned on first, and a sequence of power supply control for the equipment that had been turned on for several kilometers had to be performed.
