Abstract

A PLC system construction support tool is provided wherein a display 31 of text and numeric values is produced at the left of a paste board 22. The display 31 is provided for each row of a system and whenever a unit is added or deleted, the numeric values are updated. The display 31 contains a character string of “WIDTH” meaning the total length of the units on the corresponding row and the numeric value of the width (mm units), a character string of “CURRENT CONSUMPTION” meaning the total current consumption of the units on the corresponding row and the numeric value of the current consumption (mA units), and a character string of “WEIGHT” meaning the total weight of the units on the corresponding row and the numeric value of the weight (g units).

Dependent claims

A Programmable Logic Controller (“PLC”) system construction support tool for simulating a selection of units and a combination thereof on a screen before a PLC system is actually constructed, said PLC system construction support tool comprising:

a first screen for displaying a list of various units which can be selected for constructing a PLC system;
and
a second screen for displaying the units selected from the first screen in the same configuration as the units would actually be disposed in the PLC system, said second screen being disposed adjacent to the first screen.

A Programmable Logic Controller (“PLC”) system program development support tool comprising:

a PLC program creation tool for creating a ladder program and creating a program converted into instruction commands to operate a PLC system in accordance with the created ladder program;
and
a PLC system construction support tool built in said PLC program creation tool for simulating a selection of units and a combination thereof on a screen before the PLC system is actually constructed, said PLC system construction support tool comprising:
a first screen for displaying a list of various units that can be selected for constructing a PLC system;
and
a second screen for displaying the units selected from the first screen in the same configuration as the units would actually be disposed in the PLC system, said second screen being disposed adjacent to the first screen.
