Controllogix Data to DELTA-V DCS

Can someone please recommend a piece of hardware that can be used to acommplish this. This would be One way communication from LOGIX to DCS. There is no room available on Local rack so this interface would have to be plugged in either via ethernet or via serial. Customer prefers serial, but location of the DCS is over 1500 feet from the PLC rack. So RS-232 is out of the question.

Have anyone implemented something similar? Things to watch out for? etc. etc.

Any and all help and suggestions would be greatly appreciated.

Thanks

If they insist on serial, 1500 feet is a bit of a killer, huh?

Black Box makes a short haul modem (http://www.blackbox.com/Store/Detai...-SHM-8211-B-Async-4-Wire-Standalone/ME800AĂR3) that I've used in the past for similar apps, but not this specifically.

Delta-V can do any of the "regular" protocols -- ethernet, devicenet, profibus... What comm protocols do they already have available on the Delta-V?

DeltaV has their own serial module, with Modbus and DF1 among the protocols. They also integrate well with Mynah's EtherNet/IP module that can communicate directly with ControlLogix.

At least, they can communicate on paper. I've had some in-depth and very negative experiences with DeltaV/Mynah's A-B related modules and do not recommend them.

If it were my system, I'd use DeltaV's second-generation Modbus serial module , or a Modbus/TCP module, and a Prosoft module on the ControlLogix side. The amount of reliability and simplicity you'll gain from using a third protocol that's well documented and understood dwarfs the hardware cost.

I agree with Ken here..almost I would stay as far away from the serial as possible. I would use the Modbus/TCP module and the prosoft module on the Control Logic Side.
I have used Anybus in place of the Prosoft with good results as well. I will admit I am not a big fan of DeltaV's but some of my customers have them. Also not since you are using Modbus you want everything in word size. I always try to group my bits and I use a chuck of consecutive words for each direction. This will save you headaches later.

Thank You all for your help.

Since the local Rack has no room for an add on card, I need and external module to accomplish this.

I came across this from Realtime Automation "460ETCMRS"

Will this be ok to interface with an DELTA-V? I have no experience what so ever with DELAT-V's. Someone else will be doing the DELTA-V side(non Native English speakers), I simply have to provide them the Read only Data from the ControlLogix and nothing will be written back to the PLC.

Just downloaded the manual and will have a look at it tonight. I also need the capability to send floating point numbers.(STIRNG DATA would also be helpful but can live without it). I have had great success with their Serial to Ethernet Gateways to CompactLogix processors and wondering if anyone else here has used this particular Modbus module.

Thanks Again.

ProSoft has an EtherNet/IP to Modbus Serial gateway (PLX31-EIP-MBS). The gateway would use an I/O connection to the ControlLogix processor and Modbus Serial to the Delta V. The module will handle floating point data and string data both. Here is a link to the manual http://www.prosoft-technology.com/content/download/18704/225156/file
