6. Function blocks
6.3 UF - User function block
6.3.1.1 General information on user function blocks
The operand comments for a user function block are managed separately from the oper-
and comments from the main program. This means, for example, that I1 ("Otto") in the
user function block can have a comment different from I1 ("Emil") in the main program.
The markers and function blocks used in a user function block have their own self-con-
tained data range. This precludes any conflicts with data from other user function
blocks or data from the main program. Likewise, the standard function blocks used in a
user function block, as well as their parameter sets, are managed separately in the firm-
ware for each function block instance.
The number of instances of a manufacturer function block that can be used in a user
function block is the same as the number that can be used in the main program. The pro-
gram is limited only by the available program memory.
When a main program is loaded onto an easyE4 device or into the current project, all
the user function blocks used in the main program will be loaded as well.
