Customized function block

Once a grouped function block is created, it is possible to lock and import it into the
function block selection field for use in future project files. The resulting function block
is called a Customized function block.
Function block diagram
A customized 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 customized function block may either be user defined or
chosen from a fixed library within the Setting and Monitoring Tool.
 It is created within the logic editor, will be listed with the other function blocks in the
function block list and will be available in all new projects on the same PC.
 Upon opening a project file containing customized function blocks on another PC,
you have the following options:
– You can import the customized function blocks into the function block listing on
the new PC for further use in new projects.
– Or you can import the customized function blocks for this project only. In this
case, they will not be listed in the function block list.
When determining the total number of function blocks within a project, the customized
function block is not counted as a single function block, but rather the total number of
blocks used within it.
How to create a customized function block:
In order to create a customized function block, you must have already created it as a
grouped function block (see Section 9.13.1).
 Open the grouped function block view by clicking on its tab.
 Click on Save as CFB... in the toolbar. The Edit Function Block Details dialog
opens.
 Enter a name for the new customized function block.
Do not enter the same name used in any function block for the new customized
function block.
