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).

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.
