block defined as being retentive must remain unchanged .

Comment section
This box can be used to enter an optional comment, e.g., in order to distinguish between
various versions of a user function block.
6.3.4 Programming a user function block
Once you have created a user function block, the view will automatically switch to the
Programming view for the user function block. Moreover, a tab with the user function
block's name and version will appear next to the Main program tab in the work pane.
User function blocks are programmed exactly the same way as a main program. The
only difference is that there are slightly fewer operands available (the list of available
operands and function blocks will automatically change to reflect this).
You should be in the Programming view for the user function block. Following is a
screenshot showing an example in which a timing relay is programmed with the flash-
ing operating mode.
