PLANT CONTROL LOGIC DESIGN SUPPORT DEVICE, PROGRAM AND PLANT CONTROL LOGIC DESIGN SUPPORT METHOD

PROBLEM TO BE SOLVED: To represent control logic for controlling a plant on a CAD diagram including software and hardware.SOLUTION: This plant control logic design support device comprises: a control logic drawing part; a CAD data storing part; a sheet determining and extracting part; and a compile & writing part. The control logic drawing part draws control logic on a software sheet by using an instruction word symbol, and draws an operation specification of a hardware in the same aspect as software control logic by using the same instruction word symbol used on the software sheet for a hardware sheet. The sheet determining and extracting part extracts CAD data including a control system of a plant apparatus from the CAD data storing part. The compile & writing part converts the extracted CAD data into an execution file executable by a plant controller and downloads the execution file to the plant controller.
