Abstract
A programmable logic controller (PLC) control device includes: a plurality of main blocks, each of which controls a corresponding one of a plurality of upper modules in a facility; a plurality of sub-blocks included in each of the plurality of main blocks and each of which controls a corresponding one of a plurality of sub-modules; and a process block included in each of the plurality of main blocks and which manages operation steps of a corresponding one of the plurality of upper modules.
Claims19
A programmable logic controller (PLC) control device comprising:
- a plurality of main blocks, each of which controls a corresponding one of a plurality of upper modules in an automated facility;
- a plurality of sub-blocks included in each of the plurality of main blocks and, each of which controls a corresponding one of a plurality of sub-modules, wherein each of the plurality of sub-blocks includes:
- an interlock management unit, which checks an operating condition of a sub-module;
- a first state management unit, which manages a status of the sub-module;
- and
- a first driving command unit, which selectively issues a drive command to the sub-module based on a state of the interlock management unit;
- and
- a process block included in each of the plurality of main blocks and which manages operation steps of a corresponding one of the plurality of upper modules,
- wherein the PLC control device controls the automated facility by controlling equipment in the automated facility, wherein each of the plurality of main blocks is associated with a separate piece of equipment in the automated facility controlled by the PLC control device.
A programmable logic controller (PLC) control method for controlling equipment in an automated facility using a PLC logic controller, the method comprising:
- generating a first main block from among a plurality of main blocks, each of which including a plurality of sub-blocks and a process block;
- generating first sub-blocks corresponding to the first main block, each of which controls a corresponding one of a plurality of sub-modules, wherein each of the plurality of sub-blocks includes:
- an interlock management unit, which checks an operating condition of a sub-module;
- a first state management unit, which manages a status of the sub-module;
- and
- a first driving command unit, which selectively issues a drive command to the sub-module based on a state of the interlock management unit;
- and
- transferring information between the first sub-blocks and the first main block, and generating a first process block for managing operation steps of the first main block;
- and
- controlling the automated facility by controlling equipment in the automated facility, wherein each of the plurality of main blocks is associated with a separate piece of equipment in the automated facility.
