Honeywell Experion DCS system and datasocket (dstp)

Hello

For a customer we need to set up datacommunication. The customer uses the Honeywell Experion DCS-system. Since the NI-OPC server doesn't support that device, is there another way of collecting/sending data to their system. 

Is there a possibility that another server (with support of the Experion DCS system) that will use the dstp?

I can use every suggestion!

Thanks!
