Introduction

This Quick start guide explains the basic procedures for the first-time use of the Mitsubishi

programmable controller MELSEC-L series CPU module (CPU module).

You can easily understand how to use the programmable controller with this guide.

Reference

●Precautions

Read "SAFETY PRECAUTIONS" in the MELSEC-L CPU Module User's Manual or "Safety

Guidelines" that is an included manual of CPU module carefully.

Caution

This Quick start guide explains operations in the programmable controller system described in

" System Configuration" (P.9).

Read the manuals referred on the following page when you design or manage the system.

Operations that can be performed using

MELSEC-L series

■Programmable controllers

The programmable controllers perform sequence control and logical operations by switching the output

of output equipment ON/OFF according to the command signal from the input equipment.

Other equipment is shown below.

Terminology

Sequence control : Consecutively processes each control step based on the fixed order or

procedure.

Logical operations: One of the basic operation methods in programming.

Logical operations consist of three basic operations: logical AND, logical

OR, and logical NOT.

Limit switch : A switch to stop the movement of mobile objects on both sides of a moving

apparatus for safety reasons.

Relay : Breaks/connects the electricity with electrical switching.

Contactor : Generally called an electromagnetic contactor to break circuits and switch

the heater.

Solenoid valve : An electromagnet with a direct/alternating current. Connected to the output

side of the programmable controller.

■Features of CPU module

MELSEC-L series programmable controllers are all-in-one programmable controllers that have the

following functions built into the CPU module. The use of these built-in functions enables you to design

a smaller-scale system.

* The illustration represents

L26CPU-BT.

Positioning function

High-speed counter function

Secure data collection is possible

with just simple setting.

CSV

format

Saving to the SD

memory card in the

CSV format is

possible.

General-purpose output function

Built-in Ethernet function

A maximum of 16 external devices can be connected via

a hub.

The reading/writing of the device data of the CPU module

and the sending/receiving of the data of the other

connected devices can be performed to/from a personal

computer and GOT.

MELSEC-L CPU Module User's Manual

(Built-in Ethernet functions): SH-080891ENG

Built-in I/O function

Single function exclusive modules become unnecessary, and

a smaller-scale system can be configured using only LCPU.

Therefore, system cost reduction can be realized.

MELSEC-L CPU Module User's Manual

(Built-in I/O functions): SH-080892ENG

Data logging function

Logging can be performed under various conditions

using the exclusive configuration tools. The collected data

can be saved to the SD memory card in the CSV format.

MELSEC-L CPU Module User's Manual

(Data logging functions) : SH-080893ENG

Built-in CC-Link function

I/O modules, intelligent function modules, and special function

modules, which are arranged separately, can be controlled with

the CPU module. In addition, a simple separately-configured system

can be designed by connecting multiple CPU modules using CC-Link.

*CC-Link function is only built into L26CPU-BT.

■System enhancement according to application

By connecting various types of modules, the system can be enhanced according to the application. As a

baseless structure is employed, the space of the control panel can be used effectively without being

limited by the size of the base.
