You might could use the MODBUS RTU version of Terminator. The Ethernet version won't talk to the DL05 at this time.

I am using an 06 to communicate with a Terminator I/O system with the MODBUS RTU. I thought I was going to use the ethernet, But it requires a ERM module to command it. This is no D0-ERM. The ECOM doesn't work for the Terminator I/O.
The catalog says that the 05 can be used as a MODBUS master/slave. According to my version of DirectSoft, the MRX/MWX commands (MODBUS Read Network/MODBUS Write Network) are not in the 05 instruction set. I guess that means your ladder needs to load the stack. (The 405 manual talks about this in chap. 4.)

You can configure the serial Modbus protocol via the PLC->Setup Secondary Comm Port in DirectSoft for the 05. Modbus is one of the supported protocols, although only Port 2 is configurable on the 05.
You can now use the RX/WX instructions to talk with Modbus slaves, although there is some work to mapping a Modbus slave register address to an DL memory address (this is one of the reasons ADC came up with the MRX/MWX instructions, you simply can use Modbus addresses).
There is a link on ADCs site to show this mapping for RX/WX instructions, but I do not know off hand where it is. If you are interested, I'm sure someone else out there knows specifically how to get to it.

From pg 4-55 of the 06 User manual Vol1 2nd Ed. :
"2. For an automated MODBUS/Koyo address conversion utility, download the file
modbus_conversion.xls from the www.automationdirect.com website. "
The next few page tell you haow to use the RX/WX commands. I imagine the 05 manual has simlar info. ( .PDF available for download http://web4.automationdirect.com/static/manuals/d0user/d0user.html )

I 've addressed Modbus devices using the RX/WX commands and, on a DL06, the newer MWX/MRX commands. The latter set is a WHOLE lot easier and, in itself, is worth the cost difference between the 05 and the 06. Throw in the cost of an RS232 to RS422/RS485 convertor and you about come in even. The translation necessary between Modbus addresses and Koyo addresses leaves code that, without a whole lot of documentation, makes no sense whatsoever.
