Is an Allen-Bradley / Rockwell Automation EDS (electronic data sheet) file required for a Digi product (specifically a Digi One IA RealPort)?

No, at least not in most cases.  When adding a driver for a Digi One IA RealPort in RSLinx, choose “Ethernet Devices” for the driver type.  It will show up as “AB_ETH-n”, where n is a number.  Enter the Digi’s IP address under station 0 and the Digi One IA RealPort will then convert Ethernet to DF-1.

 If RSLinx cannot “see” the device attached to the Digi IA RealPort’s serial port, make sure you have the correct serial port communication parameters. 
For Example, a MicroLogix PLC typically talks DF1 full-duplex CRC at 19200 bps, 8 data bits, 1 stop bit, no parity. 
If any of these parameters are incorrect, RSLinx will report an error (usually by showing an red X through the device’s icon). 

If an EDS file is required for the Digi One IA RealPort, one is available.  

1. Download the files DigiOne_IA_RP.eds and dorpia.ico (the icon file).
   NOTE: The contents of DigiOne_IA_RP.eds are listed below.
2. Place the two files in a temporary folder (i.e. C:\temp).
3. Install the EDS file for use with RSLinx:
1. Start -> Programs -> Software -> RSLinx Tools -> EDS Hardware Installation Tool
2. Select Add.
3. Select Register a Single File.  Browse to the folder where you downloaded the files.  Select DigiOne_IA_RP.eds.
4. Select Next.
5. Follow the prompts until finished.
4. The Digi One IA RealPort should now be available to RSLinx.
