Details on Function Blocks
You can use system-defined function blocks (instructions) and user-defined function blocks in the
Safety Control Unit.
Procedure to Create Function Blocks
A function block consists of a "function block definition" that is made in advance and "instances" that
are used in the actual programs.
Create function blocks in the following order.
1 Create the function block definition.
Create the algorithm.
2 Place an instance of the function block definition in the program.
Call the function block definition from a program or another function block. Y
ou can call the
same function block definition from more than one program or function block. After you place
an instance of a function block definition in a program or in another function block, you can ma-
nipulate and execute it as an independent entity
.
