本発明は、端局を介して共通の信号伝送路にそれぞれ結
合された複数の機器（例えば、計算機、入出力機器等）
の間での情報伝送方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a plurality of devices (for example, computers, input/output devices, etc.) each coupled to a common signal transmission path via a terminal station.
This relates to information transmission methods between
従来、共通の信号伝送路を用いて成る機器間で情報の授

機能は変らないとしており、そのため機器が果している
機能というものを意識せずに、たｇ相手機器を指定し、
それに対して情報の伝送を行なっている。Conventionally, when transmitting and receiving information between devices using a common signal transmission path, it has been assumed that the functions that the devices connected to the terminal station should perform do not change, so it is important to be aware of the functions that the devices perform. without specifying the other device,
In response, information is transmitted.
しかるに、例えば信頼性が要求されるシステムにおいて
は予備の計算機、端末等を用意し、成る計算機又は端末
が故障した場合には、当該計算機又は端末を切替えると
いう方法がとられる。However, for example, in a system that requires reliability, a method is used in which spare computers, terminals, etc. are prepared, and if one of the computers or terminals breaks down, the computer or terminal is replaced.
また、システムを稼動させた状態で、成る機器の保守を

他の機器によるその機能の代行が行なわれる。In addition, if it is required to perform maintenance on equipment while the system is in operation, disconnect the equipment,
The function is performed on behalf of another device.
つまり、各機器が果している機能は機器間でダイナミッ
クに変更される。In other words, the functions performed by each device are dynamically changed between devices.
このような場合、従来のた文機器を指定して情報の伝送
を行なう方式では、各機器間で機能の変更が行なわれる
ごとに機器の指定を変える必要があり、そのための処理
が煩雑で、機能の変更がダイナミックに行なわれる場合
には、実際には適用することが不可能である。In such cases, with the conventional method of specifying text devices and transmitting information, it is necessary to change the device specification each time the function is changed between devices, and the process for doing so is complicated. It is practically impossible to apply this method when changes in functionality occur dynamically.
本発明の目的は、叙上の事情に鑑み、各機器が果してい

一方、受信側の端局では自端局に接続されている機器が
実行している機能に対応したアドレス（自端局機能アド
レス）を持っており、共通信号伝送路で送られてきた情
報中の送信先機能アドレスと自端局機能アドレスが一致
するか否かを判定する。On the other hand, the terminal station on the receiving side has an address (own terminal station function address) that corresponds to the function being executed by the equipment connected to the own terminal station, and the information sent over the common signal transmission path is It is determined whether the transmission destination function address and the own terminal station function address match.
そして、一致した場合には、送信情報中の必要な情報を
自端局の接続機器に送る。If they match, the necessary information in the transmission information is sent to the connected device of the own terminal station.
また、機器の故障、保守などのため、機器相互間で機能

上述の方式をとることにより、各機器の機能がダイナミ
ックに変更される場合にも、相手機器が変更されたこと
を意識することなく、機能アドレスで指定される送受信
対の間で引き続き情報の伝送を行なうことができる。By adopting the above method, even when the function of each device changes dynamically, information can continue to be transmitted between the transmitting and receiving pair specified by the functional address without being aware that the other device has changed. can be done.
例えば、今までの相手機器が故障して、その機能が予備
