Abstract

PURPOSE:To facilitate address setting at an installation site by transmitting prescribed control data for address setting during access to a next specified address, and controlling an address setting means at a terminal equipment so that the setting content of the address setting means is changed into a specified address on the basis of the control data. CONSTITUTION:A terminal equipment 21 has the address set to [0] initially, so access to the address [0] by a load control monitor 1 detect the setting and a terminal equipment 21 returns a sent-back signal by a previously set operation program. The load control monitor 1 having received the sent-back signal sends control data CD for setting the terminal equipment 21 to an address [1] to the terminal equipment 21 during the access to the address [0] and also registers the address [1] in a storage part 7. The terminal equipment 21 fetches the control data CD in next access and drives an address switching part 13 under the control of a terminal operation processing part 10 to change the setting content of the address setting part 12 into the address [1].

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an address setting method for a terminal device in a routing control and monitoring system using time division multiplexed transmission signals.

This is an operation board section for inputting data for controlling and operating the controlled load (4) connected to the control board. On the other hand, Figure @4 shows the circuit block 1 of the terminal device (2+) (:h)..., and the side in the figure is a part of the terminal calculation processing fee that performs each bridge calculation system mwJ as a terminal device. , 11
If the address IAD of the transmission signal inputted through the input/output circuit section of the controller 6111 matches the address set in the address setting section tIz, the next control data is read in (6111).
It is something that is created. The input/output circuit section 111) has a signal of 1! j
(l, ill receives the transmission signal transmitted via ill, and stores it in the terminal arithmetic processing control 11i1 section: lα.
It also converts the monitoring data output from the control processing controller 11 into a predetermined signal format and transmits it.
This is a circuit for transmitting a return signal to the load control monitoring device Ill via II 181. Further, the address setting section +121 is set to address "0" in the initial state layer, and a circuit such as a mechanical rotary switch is connected to the address switching section so that the address setting can be changed appropriately based on the number 1- on the address switching section. 1F for O! 1, which can be set in a predetermined position, or a book such as F'i rewritable memory.At the beginning, the memory contents are "0" address VC.
It consists of data that is set and can be freely rewritten to the data content indicating a predetermined address by the signal of the ATS switching unit 0!1, and the content of this address setting @US becomes the address of the terminal device. The switching section .alpha.4 is for changing the content of the address setting section .alpha. based on the control signal from the terminal arithmetic processing control section 11.alpha. based on the control data 9CD from the load control monitoring device 111. f
Reference numeral 14 denotes a control output circuit section, and this control output circuit section α4 operates, for example, as a latch stop relay, by a signal from a load control monitoring device + 11 and a control processing control section a 1101 based on the control data CD of Rikishima et al. It drives the relay and turns on or off the controlled load +41. In the U*ri monitoring input section, the contact of the latch signal is connected to the monitoring input section 1151, and the state of this contact is input as a monitoring signal of the operating state of the controlled load 14). The monitoring number 4F4 is taken in by the terminal arithmetic processing control section 11α, and is sent back to the load control monitoring device 111 as monitoring data by means of a return signal.
