5.2 Creating a Project Create a POU (three program blocks) for Structured Ladder/FBD program, and register the three program blocks created in the POU to a task. When you create a new project, GX Works2 automatically creates the Program File, Task and POU shown in the table below. Item Name Program Setting (No Execution Type) MAIN Task Task_01 The program block "POU_01" is registered in "Task_01". POU POU_01 2 CREATED PROGRAM AND SYSTEM CONFIGURATION Table 5.
GX Works2 5 CREATING TWO OR MORE PROGRAM BLOCKS 3. Select "POU" "Program" on the Project view, right-click "Program", and then select the menu item "Add New Data". The "New Data" screen appears. 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.
5.2 Creating a Project 1 "No Execution *1 Type" "MAIN" Task_01 on the Project view, right-click the Task_01, and then select the menu item "Open Task Setting". The Task Setting (task name*1) window appears. *1: The Task Name is "Task_01" for this example. OVERVIEW Select "Program Setting" 2 CREATED PROGRAM AND SYSTEM CONFIGURATION 5.
