1.2.1 Industrial Automation Protocols
IAP Device Servers, adapted to multiple factory environments, can unite any mixture of
equipment from industrial automation vendors into a single reliable pipeline. This new and
open infrastructure opens the way for data to flow in real time from all your plant devices up
to your IT layer.
IAP Device Servers are delivered with IAP Standard Tunneling protocol and can be loaded
with industrial communication protocols. The suite of protocols include DF1 (Rockwell
Automation) and Modbus (Schneider Electric). Where the IAP Standard Tunneling protocol
is limited to exclusive, standard ASCII device-to-device connections, the industrial protocols
offer connections to other devices that require special formatting or features simultaneously.
For information about using any of the industrial communication protocols, see the user
manuals on the software CD or our web site. Protocol firmware files are also contained on the
CD and new versions are available from the Lantronix web site.
You can set up the unit using the serial port, or remotely over Ethernet using Telnet or a web
browser. The CD that comes with your Device Server includes DeviceInstaller, a Windows
based configuration software that simplifies the process of installing protocols and
configuring them for use with attached devices. IAP Device Servers use Flash memory for
maintenance-free, non-volatile storage which allows for fast system upgrades.
1.3 Network Protocols (Standard Tunneling)
The DSTni-XPress DR uses TCP/IP protocols for network communication. The supported
standards are: ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, AutoIP, and SNMP. For
transparent connections, TCP/IP (binary stream) or Telnet protocols are used. Firmware
upgrades can be made with the TFTP protocol.
The IP (Internet Protocol) protocol defines addressing, routing, and data-block handling over
the network. The TCP (transmission control protocol) assures that no data is lost or
duplicated, and that everything sent into the connection on one side arrives at the target
exactly as it was sent.
For typical datagram applications where devices interact with others without maintaining a
point-to-point connection, UDP datagram is used.
