SLC 5/03 DH-485 and Ethernet

[glideratio]

Hi guys,
I have a SLC 5/03 with one free DH-485 port.
I need to transmit some data from the PLC to PC for monitoring.

There is only Ethernet/IP network available near the PLC.

Can I use a (DH-485 to Ethernet/IP) converter to transmit the data to the remote PC.

On the PC side I was going to use KEPServerEX as OPC driver.

There is also a converter abvailable on the market like Datalink DL4500
http://www.protocolconverter.com/products/dl4500EDH485.htm

But the problem I faced is I got a response from Kepware saying:

--------------------------------
We support DH-485, but only using these supported Allen Bradly cards.
Supported Network Cards
AB 1784-KT
AB 1784-KTX(D)
AB 1784-PKTX
AB-1784-PKTX(D)
AB 1784-PCMK/B
SST 5136-SD-ISA
SST 5136-SD-PCI and SST 5136-DHP-PCI

Best regards,
-----------------------------------

So I have 2 quiestions:

1) What's the point of those DH-485 / Ethetrnet converters then ?

2) Is there another solution?

I suspect that the following scheme will not work:

[PLC with DH485]----[DH485/Ethernet converter]---------ethernet-----------[PC with KEPServerEX]


But maybe this one works:

[PLC with DH485]----[DH485/Ethernet converter]---------ethernet--------[Ethernet/DH485 converter]------------[PC with KEPServerEX]


Thanks

Regards

Mike

I have used the Digi One IAP http://www.digi.com/products/serialservers/digioneiap.jsp in the past to connect serial devices to an Ethernet network.


The protocol converter was invisible to the PC on the other end, It was configured just as if it were talking to a Ethernet I/P PLC.

The more I think about it, I think that we had to switch the remote PLCs from DH-485 to DF1. (which I don't believe you can do with a SLC 5/03)

It may be worth a call to Digi to see if they can recommend a solution.
