METHOD AND DEVICE FOR CHECKING SEQUENCE CONTROLLER

摘要

PURPOSE:To provide a sequence controller checking method/device which can shorten the time needed for the debug of a sequence program. CONSTITUTION:A dummy device 24 is programmed so as to transmit a signal equivalent to a signal from an equipment to be controlled in response to the output of a sequence controller 2. Then the device 24 is connected to the controller 2 and then rewrites the input data area of the controller 2 in response to the output data received from the controller 2. Then the device 24 simulates the operation of the equipment to be controlled and confirms the operation of a sequence program 13 of the controller 2.
