2.2 The Target System
The TAC Xenta 913 includes interface drivers for a number of serial or
Ethernet communication protocols. Any target equipment that can com-
municate by means of an RS-232/485 serial network or Ethernet using
one of the supported protocols can be used with the Xenta 913.
The available types of target networks are outlined in Fig. 2.1.
The protocols used for the networks in Fig. 2.1 are described in detail in
Appendix B, “Protocols”, on page 117.

Note
• In addition to the networks described in Fig. 2.1, other combina-
tions are possible. For example, you can have a LonWorks net-
work, a Modbus master and a Modbus TCP client connected to
the Xenta 913 at the same time.
