Appropriate Modbus prefixes may need to be added to the Modbus Address depending on the
host device. For example, a “word write” fieldbus mapping in the WI-GTWY-9-xxx to Modbus
location 10, can be read by a host device as 30010 (30000 for an input re 10 as the
address). Alternatively, a “word read” fieldbus mapping in the WI-GTWY-9-xxx from Modbus
Location 1025, can be written to by a host device as 41025 (40000 for an output re 1025
as the address).
Conversely, for Modbus bit/binary commands the appropriate 0x or 1x prefix may need to be
added depending on the host device. The example below shows 8 bits being read from Modbus
