8.3.4 Modbus Configuration Settings
In Modbus configuration, parameters are named after the address of configurable Modbus
device. See the following paragraphs for the meanings of each configuration item.
z Configuration method for Modbus 8 read address, Modbus 4 read address, Modbus 2 read address
and Modbus 1 read address
Refer to the figure below for the relevant parameters to configure Modbus 8 read address. Modbus 8
read address, Modbus 4 read address, Modbus 2 read address and Modbus 1 read address have the
same parameters to set, except that the addresses of configurable Modbus device for Modbus 4 read
address, Modbus 2 read address and Modbus 1 read address are different from that of Modbus 8
read address (Therefore, only the parameter settings for Modbus 8 read address are introduced in
this section).
