DXI SAC Software: External Protocol Support

Page 4 Document DXI-APP-102-1.1

Note: These are card types defined in the DXI system, but do not do anything, as they are not implemented.

4. Host Control Protocols

Host control protocols allow an external device (usually a PC running HMI software, or a PLC) to control the DXI

system. The communications interface is usually either an RS-232 serial port or Ethernet, although other

specialized hardware can be used.

All of the TCP/IP and UDP/IP Ethernet hosts require the QNX TCP/IP software to be ordered with the SAC

computer.

4.1 Serial Port Host

This host allows controlling the DXI system using an RS-232 serial port.

This is recommended for a general-purpose serial interface to the DXI system.

4.2 TCP/IP Host

This host allows controlling the DXI system using TCP/IP over Ethernet.

This is recommended for a general purpose Ethernet TCP/IP interface to the DXI system.

4.3 Modbus TCP/IP Host

This host allows controlling the DXI system using the Modbus TCP/IP protocol over Ethernet.

This protocol is recommended for a general purpose PLC Ethernet interface to the DXI system.
