The individual actions are explained in more detail in the following.
Step 1
Setting the number of occupied CPU slots on the coordinator:

Step 2
Setting the communication flag areas:
IF...
THEN...
you use
communication flag
areas on CPs (please
consult the relevant
manuals),
you must mask out these areas (blocks) on
the coordinator without fail, to avoid
duplicated addressing of the communication
memory.
The 256 communication flag bytes can be
masked out in groups of 32. You do this by
removing jumpers at coding socket EP 7 on
Coordinator A (see Figure 6-1 for location)
or EP 60 on Coordinator C (see Figure 6-2).
