Example 1:
If the user wants to read a Modbus digital input module (DI module), Device ID is
1, data address is 10010~10019, and data count is 10 via the first TCP connection.
In this case, the user can select an “Input Relay/Coil=> 2 Bytes module”, module
parameters are shown in the below:

●
Start Address(M)
：
9
●
NO. Of Relay/Coil(M)
：
10
●
Module Type(M)
：

Example 2:
If the user wants to write a Modbus analog output module (AO module), Device
ID is 2, data address is 40001~ 40004 and data count is 4 via the second TCP
connection.
In this case, the user can select an “Output Register => 4 Words module”, module
parameters are shown in the below:
