PLANT OPERATION GUIDE DEVICE

摘要

PURPOSE:To facilitate an easy operation for an operator by detecting a delay of a sequence controller to decide its solution method based on the data base supplied previously and delivering an operation guide. CONSTITUTION:A data base 6 stores previously the data with which the working state of a device can be calculated for each step of the sequence control. When a delay is detected, the working state is calculated for the device at a delay step. This working state is compared with the actual working state of a device at a plant 1 which is supplied from a plant data input device 5. Then the operation command of the device having discordance is repeated from a delay step through the final delay end step at which the delay can be eliminated.
