characters. The following characters are allowed:
l
Uppercase and lowercase letters
l
Numbers
l
Special characters # $ % & ` ( ) + , - ; = @ [ ] ^ _ ‘ { } ~
Spaces and the \ / . : * ? < > | special characters are not allowed. The name is not case-
sensitive. If you enter a name that meets all requirements, a black checkmark will
appear to the right of the Name field. If the name needs to be corrected instead, a red
exclamation mark will appear. A new user function block will automatically be assigned
version 1.00. You can enter any version number between 0.00 and 99.99.
Programming method
You can use this drop-down menu to select the programming language (LD, FBD, ST)
for the user function block. The default is FBD. The programming language you select
here will be independent from the programming language used for the main program.
However, please note that once you create a user function block, you will no longer be
able to change its programming language.
Clicking on OK to close the "Create user function block" dialog box will create and
save the new user function block.
Once you click on OK, the empty programming unit for the user function block will be
opened and the Programming view work pane will show an additional tab with the
same name as the user function block, e.g., <UF – Blinker1V1.00>.
If you switch to the Main program tab, the user function block will appear in the list of
operands and function blocks, in the "User function blocks" folder.
6.3.3 Configuring a user function block

following methods:
Click on the Program/ Configure user function block... menu option.
Inside the pane, click on the tab with the same name as the user function block,
