PLC Processor Image
Because the 4-slot local chassis is configured for 1-slot addressing, the
first four logical groups of logical rack 0 are used for local I/O, the
remaining four groups are not used.
Logical racks 1, 2, and 3 are available for remote I/O because they are
not used by the local chassis.
