The following conventions are used to indicate and classify precautions in this manual. [. . . ] Save the function block as a function block definition file (. cxf). Read the file into another PLC project. Transferring the Program to the PLC Refer to 3-2-17 Downloading/Uploading Programs to the Actual CPU Unit. Monitoring and Debugging the Function Block Refer to 3-2-18 Monitoring and Debugging Function Blocks. 81 Procedures Section 3-2 3-2 3-2-1 Procedures Creating a Project Creating New Projects with CX-Programmer 1, 2, 3. . . Start the CX-Programmer and select New from the File Menu. In the Change PLC Window, select a Device Type that supports function blocks. These are listed in the following table.

Press the Settings Button and select the CPU Type. For details on other settings, refer to the CX-Programmer Operation Manual (W446). 3-2-2 Creating a New Function Block Definition 1, 2, 3. . . When a project is created, a Function Blocks icon will appear in the project workspace as shown below. Function Blocks will appear under the PLC. 2. Function block definitions are created by inserting function block definitions after the Function Blocks icon. Creating Function Block Definitions Function blocks can be defined by the user using either ladder programming or structured text. 82 Procedures Section 3-2 Creating (Inserting) Function Block Definitions with Ladders 1. Select Function Blocks in the project workspace, right-click, and select Insert Function Blocks - Ladder from the pop-up menu. (Or select Function Block - Ladder from the Insert Menu. ) Creating (Inserting) Function Block Definitions with Structured Text 1. Select Function Blocks in the project workspace, right-click, and select Insert Function Blocks - Structured Text from the pop-up menu. (Or select Function Block - Structured Text from the Insert Menu. ) FunctionBlock1 is displayed as the Icon under the Function Blocks Icon ( ). 2. A function block called FunctionBlock1 will be automatically inserted either after the for ladder programming language (default) or the for ST language. This icon contains the definitions for the newly created (inserted) function block. Whenever a function block definition is created, the name FunctionBlock@ will be assigned automatically, where @ is a serial number. All names must contain no more than 64 characters. Using OMRON FB Library Files Use the following procedure to insert OMRON FB Library files (. cxf). Select Function Blocks in the project workspace, right-click, and select Insert Function Blocks - Library File from the pop-up menu. (Or select Function Block - Library File from the Insert Menu. ) 2. The following Select Function Block Library File Dialog Box will be displayed. Note To specify the default folder (file location) in the Function Block Library File Dialog Box, select Tools - Options, click the General Tab and the select the default file in the OMRON FB library storage location field. 3. Specify the folder in which the OMRON FB Library file is located, select the library file, and click the Open Button.
