Save the string assignment as follows:
1. Check that the CP modules are connected to the
string which provides the intended address range
(see also chapter 1).
2. Check also that the modules are correctly marked
and that the CP cables are correctly fastened with
the union nut.
3. Now switch on the operating voltage.
The status LEDs on the CP modules and the LEDs
on the strings to which CP modules are connected,
or where the string assignment has been modified,
will now flash.
4. Now take a pen or other pointed object and press
the SAVE button on the fieldbus node.
The current string assignment will then be saved as
the nominal assignment and the appropriate ad-
dresses assigned to the CP modules.
5. Check to see that the status LEDs on the modules
light up and that the string LEDs on the node are
out (see also section 4.5).
If this is the case, all the CP modules are ready to
operate and the saved string assignment is identical
to the current string assignment.
