control component, Omron supports Function Block (hereinafter FB) with programmable
controller SYSMAC CS/CJ series and programming tool CX-Programmer V.5.0. In addition,
Omron provides “OMRON FB Library” for easier programming of data exchange with various
control components attached to PLC through various units and networks. “OMRON FB
Library” is a collection of FB software function components that you can incorporate into your
system as it is.
Omron is going to add more components to this OMRON FB Library to contribute for higher
efficiency and quality of your PLC programming.
This OMRON FB Library Start Up Guide introduces you how to connect PLC that uses
“OMRON FB Library” and other devices, with specific examples. Refer to these examples for
your design of facilities and devices using Omron’s PLC and control component.

“Function Blocks” are predefined programs (or functions) contained within a single program element that may be
used in the ladder diagram. A contact element is required to start the function, but inputs and outputs are editable
through parameters used in the ladder arrangement.
The functions can be reused as the same element (same memory) or occur as a new element with its own memory
assigned.

Function Block definition
Function Block
Instance (invocation)
Function Block definition ...This contains the defined logic (algorithm) and I/O interface. The memory addresses are not allocated in the Function Block Definition
Function Block instance(invocation) ...This is the instruction that will call the function block instance when used by the ladder program, using the memory allocated to
the instance. As the memory (addresses) used are allocated and perform individually for each Function Block instance, no error
occurs when one Function Block definition is called from more than one instances.

The following figures describe an example of a function block for a time limit circuit, to be used in the ladder. It is
possible to edit the set point of the TIM instruction to reallocate the set time for turning off the output in the ladder
rung. Using the function block as shown below, it is possible to make the time limit of the circuit arbitrary by only
changing one specific parameter.

3. Overview of the OMRON FB Library
3. Overview of the OMRON FB Library
The OMRON FB Library is a collection of predefined Function Block files provided by Omron. These files are
intended to be used as an aid to simplify programs, containing standard functionality for programming PLCs
and Omron FA component functions.
3-1. Benefits of the OMRON FB Library
The OMRON FB Library is a collection of function block examples that aim to improve the connectivity of the
units for PLCs and FA components made by Omron. Here is a list of the benefits to be gained from using the
OMRON FB Library:
(1)No need to create ladder diagrams using basic functions of the PLC units and FA components
More time can be spent on bespoke programs for the external devices, rather than creating basic
ladder diagrams, as these are already available.
(2)Easy to use
A functioning program is achieved by loading the function block file to perform the target functionality,
then by inputting an instance (function block call instruction: invocation) to the ladder diagram
program and setting addresses (parameters) for the inputs and outputs.
(3)Testing of program operation is unnecessary
Omron has tested the Function Block library. Debugging the programs for operating the unit and FA
components for the PLCs is unnecessary for the user.
(4)Easy to understand
The function block has a clearly displayed name for its body and instances. A fixed name can be
applied to the process.
The instance (function block call instruction: invocation) has input and output parameters. As the
temporary relay and processing data is not displayed, the values of the inputs and outputs are more
visible. Furthermore, as the modification of the parameters is localised, fine control during debugging
etc. is easier.
Finally, as the internal processing of the function block is not displayed when the instance is used in
the ladder diagram, the ladder diagram program looks simpler to the end user.
(5)Extendibility in the future
Omron will not change the interface between the ladder diagram and the function blocks. Units will
operate by replacing the function block to the corresponding FB for the new unit in the event of PLC
and the FA component upgrades, for higher performance or enhancements, in the future.

It is not necessary to create the
basic communications program.
A fixed name can be named to the processes.
INPUT/OUTPUT data is clear.
Parameters are easy to understand and edit.
