11 Configuring Serial or Ethernet
Communication
11.1 Overview
The Xenta 913 can exchange data with devices on networks other than
the LonWorks network. By using the serial interfaces RS-232 or
RS-485, the Xenta 913 can be configured for communication using a
serial protocol such as Modbus.
The Xenta 913 can also communicate by using the 10Base-T port on the
front and protocols that communicate over the Ethernet network, such
as Modbus TCP.
The serial port RS-232 A is on the front of the Xenta 913 and there are
screw terminals for the RS-485 connection. Use XBuilder to set up the
port you want to use.
The Xenta 913 can be either a communication master or a slave. If the
Xenta 913 is configured as a master it can communicate with several
devices on a network connected to the port. The Xenta 913 can send
data to control functions in other devices and it can also request data.
When the Xenta 913 is configured as a slave, it acts as any other slave
on the network; this means that it can receive data at any time and can
send data to the master when requested to do so.
When communicating over the Ethernet network, the Xenta 913 can be
configured to be either a client or a server, similar to the master or slave
configuration for serial communication.
