SAFETY PRECAUTIONS (Always read these instructions before using this product.)

Before using this product, thoroughly read this manual and the relevant manuals introduced in this manual and pay careful attention to safety and handle the products properly. The precautions given in this manual are concerned with this product. For the safety precautions of the programmable controller system, refer to the User's Manual for the CPU module.

In this manual, the safety precautions are ranked as " WARNING" and " CAUTION".

Note that the CAUTION level may lead to serious consequences according to the circumstances. Always follow the precautions of both levels because they are important for personal safety.

Please save this manual to make it accessible when required and always forward it to the end user.

[Design Instructions]

[Startup/Maintenance Instructions]

WARNING

When data change, program change, or status control is performed from a personal computer to a running programmable controller, create an interlock circuit outside the programmable controller to ensure that the whole system always operates safely. Furthermore, for the online operations performed from a personal computer to a programmable controller CPU, the corrective actions against a communication error due to such as a cable connection fault should be predetermined as a system.

CAUTION The online operations performed from a personal computer to a running programmable controller CPU (Program

change when a programmable controller CPU is RUN, operating status changes such as forced input/output operation and RUN-STOP switching, and remote control operation) must be executed after the manual has been carefully read and the safety has been ensured. When changing a program while a programmable controller CPU is RUN, it may cause a program corruption in some operating conditions. Fully understand the precautions described in Section 12.9 before use.

The positioning test functions of OPR, JOG, inching or positioning data for QD75/LD75 positioning module must be executed with the programmable controller set to STOP after the manual has been carefully read and the safety has been ensured. Specially when executing the function on the network system, ensure the safety thoroughly since the machinery whose operation cannot be checked by an operator may be activated. The operation failure may cause the injury or machine damage.

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

To maintain the safety of the programmable controller system against unauthorized access from external devices via the network, take appropriate measures. To maintain the safety against unauthorized access via the Internet, take measures such as installing a firewall.

1 OVERVIEW OF FUNCTION BLOCKS

1.1 Function Blocks (FBs)

An FB is designed to convert a ladder block, which is used repeatedly in a sequence program, into a component to be utilized in a sequence program. FBs can be used in projects with labels. This manual explains FBs used in Simple projects. In the operation examples, Ladder Diagram is selected as a programming language, but Structured Text can also be selected. Note, however, that FXCPU Simple projects do not support Structured Text.

1.2 Features of FBs

Creating programs efficiently

Converting a standard program into a component as a single block enables the program to be utilized easily. As an easy utilization for a sequence program is possible, the efficiency of creating a large-scale program is improved. In addition, converting a program into a component improves program readability and eases editing and debugging.

Consistency of program quality

Converting a program into a component as an FB to utilize the program allows consistency of program quality, without relying on the technological skills of the program developers. In addition, programming mistakes which may occur at the time of utilization can be prevented.

Reducing program creation man-hours with FB libraries

With QCPU (Q mode)/LCPU, man-hours for creating a program can be reduced using FB libraries. There are FB libraries which support various devices such as CPU modules, analog input/output modules, and counter modules. FB libraries which support partner products are also supplied.

Programming languages according to the intended use are selectable

In Simple projects, Ladder Diagram or Structured Text can be selected as a programming language for FBs. The optimum programming language which meets the intended use can be selected to create FBs. FXCPU Simple project supports only Ladder Diagram.

1 OVERVIEW OF FUNCTION BLOCKS

1.3 Labels

A label is a character string which represents a device. Using labels allows a program to be created without considering devices in the program. Therefore, a program with labels can be easily utilized even for a system with different module configuration.

Global labels and local labels

There are two types of labels, global labels and local labels.

Global labels Global labels are shared among all sequence programs in a project. A specific device can be assigned to a global label.

Local labels Local labels are used only in a single sequence program. They cannot be shared even if local labels with the same name are set for multiple sequence programs. Different devices are assigned to local labels for each sequence program.
