5.6.4 PARAMETERS menu
This menu item can only be activated in RUN mode.
Manufacturer function blocks with basic parameters that you have set to + via the +/-
character in the function block editor are displayed in the PARAMETERS menu and can
be changed. It is only possible to change constants. Other operands cannot be changed.
It is also possible to change parameters via the PARAMETERS menu if you have saved
the program and therefore password protected the function block editor. This is the
point of this menu. When the password is activated and the +/- basic parameter for
each function block is set, you can allow or deny the operator of the system the pos-
sibility to change the values.
Move from the Status display to the Parameters display by pressing OK ->
PARAMETERS.
Follow the operating steps described in → Section "Assigning operands at a man-
ufacturer function block's input", page 158
5.6.5 Deleting function blocks
To remove a function block, you must remove it from the circuit diagram and from the
function block list.
Requirement: The easyE4 device must be in STOP mode.
Switch to the circuit diagram display by selecting
Main menu -> PROGRAMS -> CIRCUIT DIAGR..
Move the cursor in the circuit diagram to all the contact fields and the coil field in
which the function block to be deleted is used and press the DEL button each time.
