Introduction
This section provides information that can be used when creating function blocks (FBs) and using the Smart FB Library with a SYSMAC CS1, CJ1-H, or CJ1M Series CPU Unit (unit version 3.0 or later) and CX-Programmer version 5.0 or higher.
Features of OMRON Function Blocks
OMRON function blocks can be written in ladder language or ST (structured text) language, and conform to the IEC 61131-3 standard. The function blocks provide functions for more efficient design and debugging of the user equipment, as well as easier maintenance.

Smart FB Library

The Smart FB Library is a set of function block elements that improve interoperability between OMRON PLC Units and FA components. If this library is used, it is not necessary to create a ladder program to use basic Unit and FA component functions. This enables the user to reduce the time spent on previous task, such as determining how to use the devices functions. (CS1/CJ1H unit version 3.0 or later and CXProgrammer version 5.0 or higher)
Online Editing of FB Definitions
FB definitions can be changed during operation, so FB definitions can be edited quickly during debugging. In addition, FBs can be used with confidence even in equipment that must operate 24 hours/day. (CS1/CJ1H unit version 4.0 or later and CX-Programmer version 7.0 or higher)

Nesting

Not only can programs be created with nested OMRON FBs, it is possible to make easy-to-understand, stress-free operations by switching windows depending on conditions and displaying structures in a directory-tree format. (CS1/CJ1H unit version 3.0 or later and CXProgrammer version 6.0 or higher)

Protecting FB Definitions
It is possible to prevent unintentional or unauthorized changes or disclosure of the program by setting passwords for the function block definitions allocated in the project file and protecting the definitions based on their purpose. (CS1/CJ1H unit version 3.0 or later and CXProgrammer version 6.1 or higher)
Offline Debugging with the Simulator
The PLC programs operation can be checked on the desktop, so program quality can be improved and verified early on. Both the ladder and ST can be executed in the computer application. (CX-Programmer version 6.1 or higher and CX-Simulator version 1.6 or higher)
String Operations for Variable Support
The functions that perform string data operations in ST language not only support string variables, they also strengthen the instructions (functions) used to communicate with string data I/O. (CS1/CJ1H unit version 4.0 or later and CX-Programmer version 7.0 or higher)

FB Generation Function

Existing PLC programs can be reused and easily converted to FBs. (CX-Programmer version 7.0 or higher)

OMRON FB Library

1. What is a Function Block? 1. What is a Function Block?
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.

1. What is the ST Language?
The ST (Structured Text) language is a high-level language code for industrial controls (mainly PLCs) defined by the IEC 61131-3 standard. It has many control statements, including IF-THEN-ELSE-END_IF, FOR / WHILE loop, and many mathematical functions such as SIN / LOG. it is suitable for mathematical processing. The ST language supported by CXProgrammer is in conformance with IEC 61131-3 standard. The arithmetic functions in CX-Programmer Ver.5/6 are as follows: sine (SIN), cosine (COS), tangent (TAN), arc-sine (ASIN), arc-cosine (ACOS), arc-tangent (ATAN), square root (SQRT), absolute value (ABS), logarithm (LOG), natural-logarithm (LN), naturalexponential (EXP), exponentiation (EXPT) Reference: The IEC 61131 standard is an international standard for programming Programmable Logic Controllers (PLC), defined by the International Electro-technical Commission (IEC). The standard consists of 7 parts, with part 3 defining the programming of PLCs.

5. Example Application in a Ladder Program
The following example shows the FB used in a ladder program. The X-axis and Y-axis target values are set in D0 and D2. If bit W0.0 is turned ON, the communications are performed in the FB and the command values are output to D10 and D12.

CASE Statement Examples Example 3 CASE a + 3 * b OF 1, 3 : b := 2; 7, 11 : c := 3.0; ELSE d := 4.0; END_CASE;
In this example, the CASE statement will be evaluated and then compared with each of the CASE statement comparison values (i.e. 1 or 3 and 7 or 11 in this example). If the value of variable "a" plus 3 multiplied by variable "b" is 1 or 3, then that statement-list will be executed (i.e. b:=2;). Control will then pass to the program steps following the END_CASE clause. If the value of variable "a" plus 3 multiplied by variable "b" is 7 or 11, then that statement-list will be executed (i.e. c:=3.0;). Control will then pass to the program steps following the END_CASE clause. If the value of variable "a" plus 3 multiplied by variable "b" is not 1, 3, 7 or 11, then the statement-list in the ELSE condition (i.e. d:=4.0;) will be executed. Control will then pass to the program steps following the END_CASE clause.
Example 4 CASE a OF -2, 2, 4 : b := 2; c := 1.0; 6.11, 13 : c := 2.0; 1, 3, 5 : c := 3.0; ELSE b := 1; c := 4.0; END_CASE;
In this example, the CASE statement will be evaluated and then compared with each of the CASE statement comparison values, i.e. (2, 2 or 4) and (6 to 11 or 13) and (1, 3 or 5) in this example. If the value of variable "a" equals -2, 2 or 4, then that statement-list will be executed (i.e. b:=2; and c:=1.0;). Control will then pass to the program steps following the END_CASE clause. If the value of variable "a" equals 6, 7, 8, 9, 10, 11 or 13 then, that statement-list will be executed (i.e. c:=2.0;). Control will then pass to the program steps following the END_CASE clause. If the value of variable "a" is 1, 3 or 5, then that statement-list will be executed (i.e. c:=3.0;). Control will then pass to the program steps following the END_CASE clause. If the value of variable "a" is none of those above, then the statementlist in the ELSE condition (i.e. b:=1; and c:=4.0;) will be executed. Control will then pass to the program steps following the END_CASE clause.
EXIT Statement Examples WHILE expression DO statement-list1; EXIT; END_WHILE; statement-list2; REPEAT statement-list1; EXIT; UNTIL expression END_REPEAT; statement-list2; FOR control variable := integer expression1 TO integer expression2 [ BY integer expression3 ] DO statement-list1; EXIT; END_FOR; statement-list2; The statement-list is a list of several simple statements. The EXIT keyword discontinues the repetitive loop execution to go to the next statement, and can only be used in repetitive statements (WHILE, REPEAT, FOR statements). When the EXIT keyword is executed after statementlist1 in the repetitive loop, the control passes to statement-list2 immediately. Example 1 WHILE a DO IF c = TRUE THEN b:=0;EXIT; END_IF; IF b > 10 THEN a:= FALSE; END_IF; END_WHILE; d:=1; Example 2 a:=FALSE; FOR i:=1 TO 20 DO FOR j:=0 TO 9 DO IF i>=10 THEN n:=i*10+j; a:=TRUE;EXIT; END_IF; END_FOR; IF a THEN EXIT; END_IF; END_FOR; d:=1;
