Modbus Slave Scenario
In addition to behaving as a Modbus Gateway, there is
an integrated Modbus Slave option for providing device
status, such as Cellular Network and DI/DO status, to
remote Modbus Master via Modbus communication.
With the Slave option enabled, the Modbus Master
device can request the information or send control
commands to the IoT Gateway, the Modbus TCP/RTU
Slave device. The IoT Gateway executes corresponding
processes and replies to the Modbus Master devices.
