Resulting Slave Allocations
Slaves are allocated as follows. Before a user program can access the following areas, a user-
defined variable that specifies the AT specification of that allocation area must to be defined.
OUT area 1
IN area 1
Changing the Master User-set Allocations Switch to TRUE
Change *_Sw1MstrAlocCmd (Master User-set Allocations Switch) to TRUE. The Master User-set
Allocations Switch will read the allocation results data for the above slaves and create a scan list
based on data for slaves that are actually online prior to starting remote I/O communications with the
scan list enabled.
