Function Blocks - Omron CP1L CPU Getting Started Manual

Function Blocks

Function blocks are programming elements (templates) that group a set of
processes (functions) into a single block. The user can define a function block in
advance, and then use it by simply inserting it into a program and setting its I/O.
Create and save standard program sections as function blocks. The function
blocks can then be placed in a program, and be easily reused by simply setting the
I/O parameters.

T1
Take a ladder program for "Device 1 Control".
Replace the program I/Os with parameters. Save the algorithm as a template.
The template is defined as a function block (FB).
Define as function block
Insert function block instance
into ladder program
The defined function block can be used in ladder programs as function block
instances.
