[Design Precautions]

WARNING

● For the operating status of each station after a communication failure in the data link, refer to Page 53, Section 8.1 in this manual. Incorrect output or malfunction due to a communication failure may result in an accident.

● When connecting a peripheral with the CPU module or connecting a personal computer with an intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

● Do not write any data to the "system area" of the buffer memory in the intelligent function module. Also, do not use any "use prohibited" signal as an output signal from the CPU module to the intelligent function module. Doing so may cause malfunction of the programmable controller system.

[Design Precautions]

WARNING

● If a communication cable is disconnected, the network becomes unstable, causing communication failure in multiple stations. Configure an interlock circuit in the program to ensure that the entire system will always operate safely even if communications fail. Incorrect output or malfunction due to a communication failure may result in an accident.

[Design Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

[Installation Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before mounting or removing a module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

[Installation Precautions]

CAUTION

● Use the programmable controller in an environment that meets the general specifications in the Safety Guidelines provided with the CPU module or head module. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

● To interconnect modules, engage the respective connectors and securely lock the module joint levers. Incorrect interconnection may cause malfunction, failure, or drop of the module.

● Do not directly touch any conductive parts and electronic components of the module. Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction.

[Wiring Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Failure to do so may result in malfunction due to noise.

● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.

● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable with connector, hold the connector part of the cable. For the cable connected to the terminal block, loosen the terminal screw. Pulling the cable connected to the module may result in malfunction or damage to the module or cable.

● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.

● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation.

● Use cables specified by CC-Link Partner Association for a CC-Link/LT system. If not, the performance of the CC-Link/LT system is not guaranteed. For network wiring, follow the specifications in this manual. If not, normal data transmission is not guaranteed.

[Startup and Maintenance Precautions]

WARNING

● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.

● Shut off the external power supply (all phases) used in the system before cleaning the module. Failure

to do so may result in electric shock.

[Startup and Maintenance Precautions]

CAUTION

● Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.

● Shut off the external power supply (all phases) used in the system before mounting or removing a

module. Failure to do so may cause the module to fail or malfunction.

● After the first use of the module, the number of connections/disconnections is limited to 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.

● Before handling the module, touch a conducting object such as a grounded metal to discharge the static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

CHAPTER 1 CHARACTERISTICS OF CC-Link/LT

SYSTEM

This chapter describes the features and application of a CC-Link/LT system.

1.1 CC-Link/LT System

A CC-Link/LT system is a wire-saving network system used inside a control panel and equipment, making complex

wiring unnecessary and preventing incorrect wiring.

This system simplifies wiring among sensor, actuator, and controller, providing advanced functionalities such as high-

speed response time.

1.1 CC-Link/LT System

1.2 Features

This section describes features of CC-Link/LT.

(1) Easy connection/disconnection of communication cable

By using dedicated connectors, communication cables can be connected/disconnected with one simple motion.

This allows modules to be easily extended, added, and changed.

Using dedicate flat cables, VCTF cables, and flexible cables leads to reduction in wiring work and cable cost.

(2) No parameter settings

Network parameters for operating a CC-Link/LT system need not to be set.

(3) Simplified programming

CC-Link/LT link devices are assigned for X/Y devices of the CPU module. This allows creating programs using

only X/Y devices without considering the network.

(4) Transmission speed auto-tracking function

Transmission speed setting is required for the master module only and is not required for remote stations.

(5) Slave station cutoff function

Even if a module goes down due to an error, communications among the other modules will continue.

Note if the cable on the trunk line is disconnected, data link among all stations will fail.

(6) Automatic return function

When a disconnected module recovers from an error, it automatically returns to the network and restarts data link.

3.3 I/O Signal List

This section describes I/O signals of the master module for the CPU module.

Input signals (X) are assigned to the remote input area, and output signals (Y) are assigned to the remote output area.

No special I/O signal is required to operate the master module.

I/O assignments vary depending on the point mode setting.

"n" in the following tables indicates the start I/O number of the master module.

When the start I/O number of the master module is "X/Y30"

Ex.

Xn0 to XnF→X30 to X3F

Yn0 to YnF→Y30 to Y3F

If the number of occupied I/O points is set larger than the maximum number of link points in the 4-point

mode or 8-point mode, the excessive I/O points cannot be used.

When the point mode is in the 4-point mode and the number of occupied I/O points is set to 1024

Ex.

According to the setting, the master module can occupy 1024 I/O points in the CPU module. However, the number of

actual link points is 256 (the maximum link points when the 4-point mode is set). The rest of I/O points (768) cannot

be used.

● If remote station numbers are duplicated, the duplicating stations may cause malfunction (incorrect input/output). Check that the remote station numbers are not duplicated before powering on the system.

● A remote station may occupy multiple station numbers depending on the point mode setting and the number of I/O points of the remote station. When using a remote station having the number of I/O points of eight or more, check that the station number of the remote station is not duplicated with that of the next station.
