7-1-7 Instructions
Instructions are the smallest unit of the processing elements that are provided by OMRON for use in
POU algorithms. There are FB instructions and FUN instructions.
Programs and user-defined function blocks consist of a combination of these instructions.
You can press a shortcut key to display help for an instruction.
Select an instruction that was previously entered in the FBD editor or select an instruction in the
Instruction Navigator in the Toolbox, and then press the F1 Key.
An instruction refers to a system-defined function or function block. The following table shows
the relationship between user-defined and system-designed functions and function blocks.
Refer to the NX-series Safety Control Unit Instructions Reference Manual (Cat. No. Z931) for details on
instructions.
You can display help with a shortcut key with Sysmac Studio version 1.12 or higher.
