You may change the allocated addresses at any time by means of the
Siemens STEP
7 manager. In this way you may also change the addres-
ses of analog modules to the range covered by the process image (0...127)
and address digital modules above 127.
The following pages describe the required preparations and the procedure
for this type of configuration.
