CONTROLLING SYSTEM, ASSISTANCE DEVICE, CONTROLLING DEVICE, AND CONTROL METHOD

摘要

A time synchronization signal for time series data collected from multiple controlling devices of a PID process is provided. An assistance device concurrently transmits a time confirmation signal to respective controlling devices in a predetermined time confirmation cycle, and the controlling devices forcibly output time confirmation data for synchronizing control data related to the respective controlling devices with each other as a manipulation variable in one control cycle immediately after receiving the time confirmation signal. The time confirmation data is an irregular value that is not outputted as a value of the manipulation variable in a control cycle during a steady control state.

主权项

1. A control system comprising:
a plurality of controlling devices that each output a manipulation variable to a facility; a data collecting device coupled to at least one of the plurality of controlling devices, the data collecting device configured to sequentially collect control data including the manipulation variable as time series data; and an assistance device coupled to each of the plurality of controlling devices, the assistance device configured to concurrently transmit a time confirmation signal to each of the plurality of controlling devices in a predetermined time confirmation cycle, wherein the manipulation variable comprises a value calculated based on an input set value and an input control variable in a steady control state and comprises a time confirmation data in response to receiving the time confirmation signal.
