Block ID, block number,
address assignment list
The parameters are only relevant if you select the "manual" mode.
You must then create an assignment list in a data block in which the
48 available memory fields (or less) are assigned to the maximum 12
links. This function is particularly useful when some CPUs transfer
more data than others.
The CPUs not involved in the multiprocessor communication do not
need and should not have memory fields assigned to them.
The parameters
•• block ID,
•• block number
and
•• start address of the assignment list
specify where the assignment list is stored.
Block ID
ID = 1: DB data block
ID = 2: DX data block
ID = 0 or 3 to 255 : illegal, causes an
initialization conflict
Block number
For the block number, you specify the number of the DB or DX data
block in which the assignment list is stored.
Start address of the
assignment list:
Along with the block ID and number, this specifies the area (or more
precisely, the start address of the area) in the data block in which the
assignment list is stored.
As the address of the assignment list, specify the data word number at
which the assignment list begins in flag bytes FY x+4 (high byte) and
FY x+5 (low byte).
