Anyone has acutal experience with installation and configuration of ABB DataLink?
Technically, it should be possible to be used to transfer data between different connectivities and OPC servers?
Any comments on its functionality, reliability and ease of configuration?

We used it a few years ago to link an ABB MOD300 DCS to an AC800M based QCS system.
It is a fairly simple OPC mirror, but it is reasonably easy to configure and it did work quite reliably. Most importantly the software was much more "gentle" on the MOD300 OPC servers, which would struggle to supply data reliably to any other non ABB OPC clients. We also found that the MOD300 opc server really could not handle Property Transfer aspects either.
So yes, based on that experience I would recommend it for older DCS systems like MOD300, DCI, Infi-90 etc where the OPC server performance is not good. For AC800M it is not required.
Most OPC transfer problems have very much in common with refuelling your lawnmover!
- Source has almost indefinite bandwidth (your petrol can)
- Destination has very often a small bandwidth (your lawnmover's fuel tank)
- Overfill protection does not exist
- Superstition in fuel funnel
99% of the problems boils down to that the destination OPC server can't cope with the speed of the source and that failed writes are either not handled, or re-write attempts makes the problem go even worse.
An AC800 or AC400 OPC server can serve thousands after thousands of items per second but only digest a few...
