How to Convert AB DeviceNet To RS232

Can any one tell me how to convert DeviceNet to RS232?

What happen in my place is we try to use AB RSLogix PLC to communicate with Baldor RPB SMCC communication module which is 16 year old technology. We try convert DeviceNet to RS232 using HyperTerminal to test the output, but we got no luck to get the link with the AB and the SMCC card. any one have done this before?
 
You cannot directly convert devicenet to RS232. I suggest you source out some serial converter to interface your devicenet to RS232. You must know also how to write an EDS file for you to configure your devicenet network. A lot of brands you can buy and interface with the said protocols.

Not sure how to do it with AB but it can be done with a WAGO DeviceNet Programmable Controller, a serial I/O module, and a function block created in WAGO's IEC 61131 programming tool.

On solution is to use a PC based protocol converter based on ISaGRAF, you need: 1- an inexpensive SBC (QNX4 compliant) that has a PC/104 connector, the SST 5136 DNET card, and the ISaGRAF runtime, which has both the SST DeviceNet driver and a generic serial communications package. You will be able to then R/W DeviceNet data and send appropriate messages to the Baldor using Send/Receive comm function. ISaGRAF has been used many times to do this kind of work.
