PURPOSE:To generalize data transmission and reception easily by providing each controller with an input and an output terminal data part, and writing data in the input terminal data part according to a connection table. CONSTITUTION:Respective controllers C1-CN which have process control functions of feedback control and sequence control are connected mutually by a micro data way L, and a higher rank computer U is further connected thereto to constitute a distributed digital instrumentation control system, so that the controllers C1-CN perform complex control associatively with one another. For this purpose, the controllers C1-CN are each provided with software for connection with other controllers as an input and an output terminal data part. Data of the output terminal data part is transferred and stored in others by the connection table at a specific period, and this is inputted to the input terminal data part by software wiring. |
