User Reads setup data from the Slave User Allocations Setup
Table in the DM Area and registers slave user-set alloca-
tions.
Once registered, the Unit will operate with slave user-set
allocations regardless of whether the power is turned
OFF and back ON again until slave communications are
disabled (i.e., until Slave Disable Switch (word n+1, bit
07) is turned ON).
Slave communications must be disabled before this
switch is turned ON.
Note After the switch is turned ON, turn the Slave
Enable Switch (word n+1, bit 06) ON to enable
user-set allocations.
