B.3 Modbus TCP Client
The Xenta 913 can be configured to act as a client to a Modbus TCP
server to allow monitoring and control of one or more slave devices
through an I/NET or LON control system. Both the RTU and ASCII
protocol formats are supported.
A number of Modbus Registers can be connected to a corresponding set
of LON Network Variables or I/Net Points to allow one or more Slave
devices to be monitored and controlled. The Xenta 913 acts as a net-
work Client, exchanging the required register values with the slaves
through a Modbus TCP Server.
