Modbus Address Table
WISE allows SCADA software or HMI device to retrieve the I/O channel data and
system information via Modbus TCP/RTU protocol. WISE register addresses are
specified according to Modbus register mapping tables (more detailed information
will follow).
Please Note:
The addresses are in
Base 0
format
The addresses are in
Decimal
format
The
default value of NetID is 1,
and you can modify the NetID value in the
Ethernet Setting page. (Please refer to “

If the data is displayed in Floating format or 32 bits format (AI/AO Channel
value
、
Internal Register value
、

each record of data will take two registers to hold the data.
If the data of Internal Register is displayed in Double or 64bit, each record of
data will take four registers to hold the data.
