Logic programming – Function blocks
9.13 User defined function blocks
9.13.1 Grouped function block
Function block diagram
You can select groups of function blocks in order to create a single grouped function
block. The typical purpose of a grouped function block is to simplify the re-use of
groups of logic and to reduce the number of function blocks on a page.
A grouped function block has the following characteristics:
 It can have a maximum of 8 inputs and 8 outputs.

It cannot contain the Fast Shut-off function block nor another grouped or
customized function block.
 The icon representing the grouped function block is chosen from a fixed library
within the Setting and Monitoring Tool.

It is created within the logic editor, but is not listed in the function block list.
 It is saved with the project file. Upon re-opening the project file on another PC, the
grouped function block will be displayed.

It can be saved as a customized function block.
When determining the total number of function blocks within a project, the grouped
function block is not counted as a single function block, but rather the total number of
blocks used within it.
How to create a grouped function block:
 Select the function blocks which are to be grouped.
 Right click on one of the selected function blocks to call up the context menu.
