Title:
DEVICE FOR VERIFYING OPERATION OF SEQUENCE CONTROL PROGRAM
Document Type and Number:
Japanese Patent JPH08227301
Kind Code:
A
Abstract:
PURPOSE: To make it possible to simulatively generate an input signal corre sponding to a control signal outputted by a sequence control program(SCP) from a plant and to verity the operation of the SCP by a host management computer for developing the SCP.
CONSTITUTION: The host management computer 1 for developing an SCP is constituted of a program decoding part 5 for inputting a program part 3a and a constant 3b in the SCP 3 from an SCP developing part 2, decoding the inputted contents and storing information for outputting a time chart in a decoded result storing file 6 and a decoded result editing part 7 for reading out the information from the file 6, editing the read information like a time chart type and outputting the edited result.
