Title: Sequence controller
Inventor: UEDA AKIHISA
IPC: G05B19/05
Filed: 1982-12-24
Abstract: PURPOSE:To realize abundant monitoring and a change in program constant without increasing the processing time of a sequence controller by allowing a main frame, monitor part, etc., to share a memory. CONSTITUTION:When the main frame 1 performs processing, writing to the RAM8-2 of the monitor part 2 is carried out simultaneously with writing to an RAM8-1. When addresses of both RAMs are made coincident with each other, the writing is unchanged since there is not any extra time. When monitoring is commanded on the keyboard of a key input circuit 13', the CPU3' of the monitor part 2 interrupts the writing to the RAM8-2 of the monitor part 2 from the main frame 1 to decides on the operation state of the reading from the CPU3' to the RAM8-2, and sends the result to a display circuit 6. The processing of the main frame is still carried on and the processing time does not become longer. Visual confirmation is done in the monitoring and there is no influence even if data is updated in the reading of the RAM8-2. Further, data necessary for the monitoring are all stored in the RAMs, so there is no limit of monitor information.
