Installing Using the Modbus TCP to RTU Gateway Function
The gateway function is transparent. When a command is sent on Modbus TCP it is translated to
Modbus RTU. The response is translated back to Modbus TCP and delivered to the
Modbus TCP
Client
.
It is possible to connect Bolt Serial to a pre-existing wireless infrastructure, such as the wireless
network in a production facility.
