About the Digi One IAP
Key features
The Digi One IAP is high-performance, flexible device server that meets the specific requirements of
the industrial automation (IA) market. It delivers simple, reliable and cost effective network
connectivity for serial devices common in industrial automation applications, such as
Programmable Logic Controllers (PLC), CNC/DNC (Computerized Numerical Control/Direct
Numerical Control) equipment, process and quality control equipment, bar-code readers, operator
displays, scales and weighing stations, printers, vision systems, and many other types of
manufacturing equipment.
Features include:
An industrial-strength, ergonomic enclosure designed to mount on a standard DIN rail
EIA-232/422/485 switch select ability for use with virtually any device with a serial port, and
expanded supply voltage range of 9-30 VDC with screw terminal connections or the industry’s
first powered Ethernet option (802.3af) that eliminates the need for an external power supply.
RealPort® COM Port redirection technology
Easy web-based configuration
Multi-master capability
Easy management through SNMP.
Flexible Industrial Automation support
The Digi One IAP support for IA protocols is exceedingly flexible, providing connectivity solutions in a
wide variety of industrial automation environments. It supports the following:
Multi-mastering, which means that a slave using any supported serial port protocol can be
managed by multiple masters; the masters need not use the same network protocol to access
the device server.
A variety of serial-port protocols, including Modbus ASCII, Modbus RTU, DF1 Full-Duplex,
Compoway/F, FINS, and Hostlink. Support extends to what Digi calls the “user-defined” protocol,
which is any serial protocol that has fixed header and trailer strings that bound all message
packets and where each protocol request is followed by a single response.
Almost any other IA serial device, master or slave, as long as the device on the other side of the
network can communicate using TCP sockets, UDP sockets, or COM Port redirection (using
RealPort).
Several methods to encapsulate serial data across a network, including Modbus/TCP, Ethernet/
IP, Allen-Bradley Ethernet, TCP sockets, UDP sockets, and COM Port redirection (using RealPort).

Digi One IAP 9
About IA configuration profiles
Port profiles simplify serial port configuration by displaying only those items that are relevant to the
currently selected profile.
There are several port profile choices for the Digi One IAP, on the Serial Port Configuration page of
the web interface. If a port profile has already been selected, it appears at the top of the Serial Port
Configuration page in the web interface. Everything displayed on the Serial Port Configuration page
between Port Profile Settings and the links to the Basic Serial Settings and Advanced Serial
Settings depends on the port profile selected.
You can change the selected profile or modify individual settings of a selected profile.
Key terms in IA configuration profiles
IA configuration profiles involve the following key terms and concepts:
Com port redirection
A method of redirecting the serial data generated by a PC-based master to a slave connected to a
port on a network-based device server. In this scheme, the master “thinks” it is communicating with
a device connected to a serial port on the PC system when, in fact, the data is encapsulated in
network packets and transported across the network to a device connected to a serial port on the
Digi One IAP. Many applications, written to support serial communication only, require this service
in order to communicate over the Ethernet.
IA
Abbreviation for industrial automation.
master (or protocol master)
The host or IA device that initiates all communication with a protocol slave.
multi-master
Any configuration in which more than one master simultaneously communicates with a slave.
protocol request
A message generated by the master and sent to the slave that requests information or issues a
command protocol response a message generated by the slave in response to a protocol request
from the master.
slave (or protocol slave)
The device that responds to requests from the master.
TCP socket (or TCP socket service)
A type of network service that uses TCP to ensure reliability. When this guide discusses TCP sockets,
it means that IA protocol messages are encapsulated in network packets and transported across the
network using a standard network service. Many applications support connections to devices using
TCP socket.
TCP tunnel
A TCP socket connection in which a master is connected to the serial port of one device and a slave
to the serial port of another device.

Configure the Digi One IAP using IA profiles Serial bridge profile: master and slave connected to Digi ports
Digi One IAP 10
UDP sockets (or UDP socket service) similar to TCP socket service (discussed above) except that the
UDP protocol is used instead of TCP, which means that the reliability service TCP performs is not
provided. Advantages of UDP socket service are slightly less protocol overhead and support for
multicasting. Some applications support connections to devices using TCP socket.
UDP tunnel
A UDP socket configuration in which a master is connected to the serial port of one device and a
slave to the serial port of another device.
Serial bridge profile: master and slave connected to Digi ports
Use the Serial Bridge profile to connect a protocol master to the serial port of one device server and
the protocol slave (or slaves) to the serial port of another device server. This profile, which is often
called a serial bridge, is applicable to environments that use most IA serial port protocols and to
multi-master environments as well. The network is completely transparent to the serial devices,
which means they do not have to be reconfigured.
Configuration requirements
The serial port connections must be configured to meet the requirements of the attached device,
which can be one of the following:
Modbus ASCII
Modbus RTU
DF1 Full-Duplex
Omron Hostlink
Omron FINS
Omron CompoWay/F
A serial port protocol that meets Digi’s definition of a “user defined” protocol, that is, one that
has fixed header and trailer strings that bound all message packets and where each protocol
request is followed by a single response.
For the network connection, Digi recommends TCP sockets, which works regardless of the serial port
protocol specified and provides an efficient and reliable network service. Another option is UDP
sockets, which also works with all the serial port protocols, although it lacks TCP socket reliability.
For Modbus devices, Modbus/TCP is an option, and for DF1 Full-Duplex devices, Allen Bradley
Ethernet and Ethernet/IP are options.

Configure the Digi One IAP using IA profiles Modbus profile: serial-connected slave
Digi One IAP 11
Modbus profile: serial-connected slave
Use the Modbus profile to connect a slave device (or devices) using Modbus RTU or Modbus ASCII.
This profile is applicable to environments in which multiple masters control the slave or slaves.
Configuration requirements
The serial port connection must be configured for the protocol required by the slave, in this case
Modbus RTU or Modbus ASCII.
The network connection usually does not require configuration. The only exception is if the master
requires COM port redirection. In that case, the master is an application that resides on a PC, such as
a Microsoft Windows system, and communicates only with devices on COM ports.
Setup information
To configure the serial port for Modbus ASCII or Modbus RTU, see Configure a serial-connected
slave: generic procedure on page 14.
To set up a PC and the device server for COM port redirection using RealPort, see Set up COM port
redirection on page 16.
Modbus profile: serial-connected master
Use the Serial Connected Master profile to connect a master device using Modbus RTU or Modbus
ASCII to the serial port of the device server.
Configuration requirements
The serial port connection must be configured for the protocol required by the master, in this case
Modbus RTU or Modbus ASCII. If the remote slave supports TCP socket communication, which is the
case if the remote slave is connected to another device server, Digi recommends this option.
Modbus/TCP is the other supported network option. This master can be configured to control up to
8 slaves.
Setup information
To configure the port for Modbus ASCII or Modbus RTU and the network for TCP socket
communication, see Configure a serial-connected master: TCP/UDP sockets on page 15.

Configuration requirements
In this configuration, you do not set up the port of the device server for an IA protocol; instead:
If you will use RealPort for COM port redirection, you simply set up the port for RealPort.
If you will have the master access the device server using TCP or UDP sockets, configure the
standard serial port parameters required by the attached slave, such as line speed, number of
data bits, and parity scheme.
No special network configuration is required in either case.
Setup information
To set up the device server for RealPort, see Set up COM port redirection on page 16.
To set up the port for an “unsupported” IA protocol, see Configure a serial-connected slave: other
IA protocol on page 15.
