Configure Serial Port Settings
22 Chapter 1 Command Line Configuration Tasks
Configure Industrial Automation (IA)
To configure how devices in an industrial automation (IA) environment
communicate, use the “set ia” command.
See "set ia" on page 125 for command syntax, option descriptions, and
examples. The syntax for “set ia” varies according to the IA device being
configured: serial port-connected devices, network-based masters,
network-based slaves, and destination tables for forwarding messages.
The “set ia” command description shows these syntax variations, the
effects of the command options for each variation, and examples of
configuring several IA devices.
Protocols for IA Devices
IA devices can use various communication protocols, including Modbus
variations (Modbus/RTU, Modbus/ASCII, and Modbus/TCP), AB/DF1 Full-
Duplex and AB/DF1 Half-Duplex, Hostlink, AB/Ethernet (CSP), Ethernet/IP,
and a Custom (or “user-defined”) protocol.
Recommendations on Configuring Industrial Automation
Due to the flexibility involved, manual configuration of IA scenarios by
command line is recommended for advanced users only. New users are
encouraged to use the Industrial Automation Wizard under the Applications
section of the Web Browser interface.
Where to find more information on Industrial Automation
Besides the “set ia” command description, additional information on
configuring Industrial Automation is available at the following URL:

Configure Modem Emulation
Modem emulation enables a system administrator to configure a
networked Digi device server to act as a modem.
See Chapter 3, "Modem Emulation Commands" for more information on
modem emulation.
Configure TCP Socket Communication
Transmission Control Protocol (TCP) socket communication enables serial
devices to communicate with each other over an Ethernet network as
though they were connected by a serial cable.
To configure TCP socket communications, use the “sockets” option on the
“set config” command. See "set config" on page 97.
Configure UDP Multicast Communications
User Datagram Protocol (UDP) multicast is used to send serial data over
an Ethernet cable to one or many hosts at the same time.
To configure UDP multicast communications, use the “set udpdest”
command. See "set udpdest" on page 225.
