PLC system construction support device

摘要

PPROBLEM TO BE SOLVED: To prevent a mistake in arrangement of units without largely causing negative effects on user's flexibility. PSOLUTION: A PLC (Programmable controller) system construction support device 10 performs selection of configuration units and simulation of their combinations on a screen prior to actually constructing a PLC system. The PLC system includes a display screen creating section 26 which creates: a unit component information display screen which displays various unit lists selectable in constructing the PLC system; a unit configuration information display screen which displays a status wherein the units selected from the unit list are arranged to a base unit of the PLC system; and a prediction object candidate list display screen which displays a next operation object unit which selection from the unit list is predicted.
