Note: For
register type “gw_info” the <word_cnt> must be 5.
When regist
er type is “gw_code_word”, the gateway’s “code word” will be exposed to Modbus. The
“code word” is read-only.
Note
: For register type “gw_code_word”, the <word_cnt> should be 16 or less.
The <EUI64> in “gw_info” and “gw_code_word” register lines should identify the WirelessHart
Gateway.
Accepted values: 001B1EF981000002, 0000000000000000, FFFFFFFFFFFFFFFF.

Notes:

When mapping the Modbus registers on the WirelessHART data entities, you must consider
the size of the WirelessHART data entity and allocate a contiguous chunk of Modbus 16-bit
registers in the Modbus addressing space to hold the entire data entity (plus an additional
Modbus register to hold the auto-generated status, if applicable). When the chunk is bigger
than the size of the data entity, it will be filled with the actual data from the lowest addressed
register to the highest, and from the MSB of each register to the LSB. If the data entity does
not entirely fill the last register, the register will have the data on the MSB and the LSB will be
set to zero.

If the address range of a register line overlaps an existing register line in the same group, or if
it does not fit in the range 0-65535, it will be ignored
