Example
10.4.4
Output Parameters
Condition code byte
This byte informs you whether the INITIALIZE function was
executed correctly and completely.
Initialization conflict
The initialization conflicts listed are recognized and indicated by the
function in the ascending order of their numbers.
If an initialization conflict occurs, you must change the
program/parameters.
All the numbers listed in Table 10-3 can occur in the condition code
byte.
You have three CPUs in your rack, CPU 2 sends a lot of data to the other
two CPUs. The other two CPUs, however, only send a small amount of data
back to CPU 2 as acknowledgements in a logical handshake. There is
no data
exchange
between
CPU 1 and CPU 3
.
The assignment list is stored in data block DB 40 from DW 0 onwards and has
the following parameters:
