* Assumes Word Mode Addressing is selected in Configuration Software
The Fieldbus IN and OUT areas can be configured to a maximum size of 1024 words (2048
bytes) each, depending on the configured fieldbus mappings. The highest mapped location will
correspond to the highest available Modbus register (or coil) available to a Modbus/TCP client.
A Modbus/TCP client must use the appropriate Modbus Coil or Modbus Word addresses
corresponding to configuration software, as well as the correct function code (see 4.12.2
Supported Commands).
