5.6 Working with function blocks
Deleting function blocks from the function block list
In order to prevent accidental deletion, a function block continues to be managed in the
function block list, even if it was already removed in the circuit diagram. To delete the
function block permanently and therefore to free up more memory, you must remove it
from the function block list.
Go to
Main menu -> PROGRAMS -> FUNCTION BLOCKS.-> Function block list
Select the function block to be deleted in the function block list, in this case CP10.
Press the DEL pushbutton.
The function block is removed from the function block list.
Press the ESC button in order to save the function block list with the deleted func-
tion block.
Confirm with the OK button.
In the function block list select the required function block.
In this example, select the data block comparator AR01 in Adder mode.
Press the OK button.
Depending on the display selected the function block is shown with the ACTUAL values
and the result, or with the set operands and constants.
If you want to switch from the operand value display to the actual value display or vice
versa while checking the manufacturer function block, press the ALT button.
Press the ALT button again.
Here are some useful tips:

Exception: Retentive data keeps its state, → Section "Retention function", page 473.
The most recent actual values are transferred to the operands every cycle. The
data function block is an exception.
