Combination of the power supply module, the CPU module, the I/O modules,
and the base unit.
Consecutively processes each control step based on the fixed order or
procedure.
General term for the programmable controller CPU available in MELSEC-QnA.
Application software to create sequence programs and communicate with the
programmable controllers.
The core module to unify the controls of the programmable controllers.
Q02UCPU is used in this Quick start guide.
Supplies electricity to each module, including the CPU module and the I/O
modules.
The unit that mounts the power supply module, the CPU module, and the I/O
modules.
A method to organize one system by combining necessary elements.
Elements such as the power supply module, the CPU module, the I/O
modules, and the base unit are combined in the programmable controller
system.
A switch to suspend mobile objects on both sides of a moving apparatus for
safety reasons.
Breaks/connects the electricity with electrical switching.
Generally called an electromagnetic contactor to break circuits and switch the
heater.
An electromagnet with a direct/alternating current solenoid valve. Connected
to the output side of the programmable controller.
Prevents electric shocks and malfunctions.
Transfers signals to other equipment. Combines such elements as breakers,
switches, protection equipment, relays, and programmable controllers.
Receives signals from switches and sensors, and supply electricity to operate
motors and solenoid valves of the machines and equipment.
A two-winding transformer.
The primary and secondary coil are wound separately to protect the secondary
load.
An input used when creating a sequence program.
An output used when creating a sequence program.
A location to store data such as ON/OFF, numeric values, and character
strings in the programmable controller.
Breaks/connects the sequence circuit by switching ON/OFF.
A program to perform sequence control.
Indicates a GX Developer project in this Quick start guide.
Consists of programs, device comments, and parameters.
Setup information necessary to operate the programmable controller system.
Modules and the network are set by writing parameters to the CPU module.
Setup information for modules, devices, and programs used in the
programmable controller system.
Numbers attached in order from the start of instruction in the sequence
program.
One of the basic operation methods in programming.
Logical operations consist of three basic operations: logical AND, logical OR,
and logical NOT.
An operation in which programmers search for and correct bugs in the
sequence program.
