Section
1. Product Overview
The Ethernet to Serial Gateway is a
product that is a combination of hardware and software that enables Omron PLCs,
temperature controllers, panel meters and other serial devices that do not have
built in Ethernet capabilities to communicate on Ethernet Network. The protocols that can be used with this converter are
HostLink (both C and CV mode) and CompoWay F.
The Digi One IA RealPort gateway can be used for programming, monitoring,
data acquisition, etc.
The hardware component of the Gateway is a DIN Rail
mountable DC Powered Ethernet to Serial Converter.
This converter plugs into a plant Ethernet Network with a user defined IP
address. It also plugs into an
Omron PLC through an RS232, RS422, or RS485 serial port.
The software component of the Gateway is a Virtual COM Port that runs on
the computer that wishes to talk to the PLC, temperature controller, or other
serial device. This Virtual Com
Port allows the hardware Ethernet to Serial converter attached to the serial
device to appear as a standard Windows Com port to an application such as CX
Programmer, FINSGateway, SysConfig, Syswin, or other windows application.

Section
4. Software Setup
The software setup is divided into 2 parts, configuring the Digi One IA
RealPort hardware using Digi RealPort Remote tool, and installing the virtual
COM port on the computer(s) that will communicate with the Omron devices using
the Ethernet to Serial gateway.
Part 1. Configuring
