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 2.  Hardware Setup         

1.      Connect 12 or 24 VDC power to the Power connector on the Digi One IA RealPort.  The polarity is marked on the device. 

2.      Set the DIP Switches as shown for RS232, RS422, or RS485 connections to the Omron device.

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 the Digi One IA RealPort Device 

1.      Install the Digi RealPort Remote software by running Setup.exe on the supplied CD.

 

2.      From the above screen, select your computer Operating System (Currently only Windows NT, 2000, and XP are supported), Hardware (Digi One), and Software (Digi Port Authority - Remote).   Then click Install Software.

 3.      Select the installation location, and click Next. 
      

4.      Select the program folder and click Next.
 

 5.      When the installation is complete, click Finish (leave Launch Digi Port Authority - Remote checked)
      

6.      In the above configuration window, click Discover to allow the Digi Port Authority Remote software to search for the connected hardware. 

7.      The software should report that a device without an IP address has been detected.  Click OK.  If the software did not find the hardware, check the power connection and Ethernet connection to the Digi One RealPort IA device and try the Discover option again.  

8.      In the configuration software, click Configure.

9.      Enter the IP address, Subnet, and Gateway (if applicable) for the hardware.  If uncertain of these parameters, contact your network administrator.  Click OK.  

10.  Wait while the software applies the settings, and tests the device. 

11.  The configuration window will appear again, with the IP address that you entered above in the Device window.  Click Configure. 

         12.  You will be asked for the User Name and Password.  The default User Name is root and the default password is dbps.  Enter these and click OK. 

13.  Your default internet application will take you to a web based setup application that runs on the Digi One IA RealPort.  Select Setup Wizard. 

14.  Select Industrial Protocols

15.  Click Next

16.  Choose the baud rate, data bits, parity, and stop bits to match the Omron device.  Omron default settings for many products are 9600, 7,E,2.  Click Next.  

17.  Select the Omron protocol that you wish to use.  Choose Hostlink for C and CV mode Hostlink , and Compoway/F for the CompowayF protocol.  For Omron PLCs use Hostlink.  Click Next. 

18.   Select Slave.  Click Next. 

19.  Verify the settings that you have made, and click Finish

20.  Click on Admin, and then click Reboot.  Click Continue.  This will restart the module, and apply the configuration changes that you have made.  

This concludes the configuration process for the Digi One IA RealPort hardware.  You can modify any of these changes at any time by launching the Digi Port Authority - Remote software from the start menu, and starting at step 11 of this section.  Please proceed to Part 2.
