Mitsubishi Electronics SW1DNC-GXW2-E User Manual

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".

WARNING

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.

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.

[Design 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.

[Startup and Maintenance Instructions]

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 GX Works2 Version 1 Operating Manual (Common) 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.

This manual explains the procedures to actually create a program (Structured Project) using GX Works2 and operate the programmable controller using the created program. If this is your first time creating a Structured Project using GX Works2, you are recommended to read this manual first, and then use GX Works2. Refer to the following manual for Simple Projects:

1 OVERVIEW

1.1 Simple Project and Structured Project

■ Simple Project

In a Simple Project, you can create sequence programs using instructions for the Mitsubishi programmable controller CPU. The Simple Project offers the same operability for program creation as the conventional GX Developer.

You can create sequence programs using the following programming languages:

● Graphic languages

• Ladder Use this graphic language to describe programs as ladders consisting of contacts, coils, etc., using the same operating procedures as the conventional GX Developer.

•SFC Use this graphic language to describe sequence control in a way easy to understand. Describe steps which specify the processing and transition conditions which specify conditions for proceeding to the next step. You can describe steps and transition conditions using the ladder language.

● Text language

• ST (Structured Text) This text language allows you to describe controls by syntax including alternative sequences offered by conditional sentences and repetition offered by repetition sentences in the same way as high-level languages such as the C language. Accordingly, you can briefly create programs easy to look at.

■ Structured Project

In a Structured Project, you can create programs by structured program. By dividing controls into small portions and making parts of common contents, you can create programs easy to understand and applicable to many cases (by structured program.)

You can create sequence programs using the following programming languages:

● Graphic languages

• Ladder Use this graphic language to describe programs as ladders consisting of contacts, coils, etc., using the same operating procedures as the conventional GX Developer.

• Structured Ladder/FBD Structured Ladder is created based on the relay circuit design technology. Because this language is easy to understand intuitively, it is used generally for sequence programs. Every ladder always starts from a base line on the left. Structured Ladder consists of contacts, coils, function blocks and functions which are connected each other with vertical lines and horizontal lines. FBD connects functions and function blocks with ruled lines to describe ladders.

Or hide Left Power Rail by clicking on the Structured Ladder/FBD tool bar. Refer to 3.1.2 for an FBD program.

Displaying or hiding left power rail

● Even while left power rail are displayed, you can create an FBD program by ignoring left power rail.

● If you try to delete a left power rail to which a function, etc. is already connected, the left power rail is not

deleted. Delete a connection to the left power rail first, and then delete the left power rail.

● It is not possible to create programs in the symbolic expression using FBD. When using FBD, create programs in the functional expression using functions and operators.

Creating two or more ladders in one ladder block

When creating an FBD program, you can create two or more ladders in one ladder block. In this case, a warning is displayed during compiling. It is possible to hide this warning by adding an optional setting.

5.1 Created Program

This section explains how to create a program for controlling a tea server system which consists of a tea pouring operation, water refilling operation and warning indicating operation. This section also explains a program which works as one Structured Project, and the program operations.

■ Tea pouring operation

When a user presses the tea pouring button X1 (that is, when X1 turns ON) while the cup detection X0 is ON, the tea pouring output Y10 turns ON and the tea server pours tea into the cup. The tea server pours tea while the user is pressing and holding the button, and stops pouring when the user releases the button. The tea server does not pour tea when the user presses the tea pouring button X1 if the cup detection X0 is OFF.

■ Water refilling operation

5 - 2

When water inside the water refill tank is running low, the lower limit switch X3 turns ON, and the water refill output Y11 turns ON. When the water refill output Y11 is ON and the water supply to the tank is sufficient, the upper limit switch X4 turns ON and the water refill output Y11 turns OFF.

■ Warning indicating operation

• When the tea server performs the water refilling operation 5 times, the tea leaf replacement indicator lamp Y12 turns ON.

• When a user presses the tea leaf replacement check button X2, the tea leaf replacement indicator lamp Y12 turns OFF.

5.1.1 Operations of program

When creating a new project, GX Works2 automatically creates "POU_01 [PRG]" under "POU_Pool". Because the language (Structured Ladder/FBD) used in this chapter is same as the language adopted in "POU_01 [PRG]", you can use "POU_01 [PRG]" by changing its data name instead of deleting it.

4. Set the "Data Type", "Language" and "Data

Click the button to create a program block and close the window.

Repeat the steps 3 and 4, and create three program blocks for the tea pouring operation, water refilling operation and warning indicating operation.
