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.
