Abstract

PURPOSE:To cope with the extension and remodeling of processes only by correcting control procedure, by generating dynamically check data in on-line mode according to the control procedure. CONSTITUTION:The state of a process is fetched by the process input-output device in the form of a digital input signal and then stored in the process state storage table by the process state fetch program. This table has respective bits corresponding to process equipments; for example, when one bit is set to ''1'', the pump that corresponds to it is in operation and when ''0'', it is not in operation. The control procedure of this sequence is perfectly determined by the control program and start and stop instructions for equipments are geneated at need. Namely, check data are dynamically generated in on-line mode according to the control procedure, so that the extension and remodeling of processes can be coped with only by correcting the control procedure.
