SLC 5/05 Open Addressing
The actual number of addresses available depends on the model of the PLC. The ranges have been opened
up to allow for maximum flexibility with future models. If the driver finds at runtime that an address is not present
in the device, it posts an error message and removes the tag from its scan list.
Note: This model has no specific addressing.
