Proprty transfer replacement
Is there any way to write 800xA data to another 3rd party OPC server other than property transfer ?
I have to transfer 2000 signals from 800xA to a 3rd party OPC server. Communication speed expected is 3second. Signals are not critical.
Also need to read 500 signals from 3rd party OPC server to ABB 800xA system.
I tried proprty transfer initially configuration working for a week then stops the data transfer but there is no failure in property transfer service.
Any suggestions appreciable.
I can not answer for any alternatives. The below could be checked to troubleshoot the Property Transfer service:
Check [Workplace Structure]Web System Workplace
- System Event List
- Operator Message List
If you see overruns or write failures, please have destination OPC server examined.
As far as I know, there is one single "write thread" in the Property Transfer service, if the thread become stuck on a write it will probably hang there for the full 30 seconds of COM timeout.
Throttle back on update rate and perhaps configure min time between writes to counter overruns and write failures.
I've seen cases where the Property Transfer service is successfully pushing 50 items per second steadily month after month. But then we are dealing with a destination OPC server with super powers; it will swallow more or less everything you throw at it within a couple of milliseconds. Most OPC servers are poor on writing.
The Pulp & Paper group have an "OPC Transporter" that can be used stand alone. We've used this on several paper mills for 3rd party comms. Its quite reliable and robust since the AC800M based QCS relies absolutely on it. (unfortunately it does not work very well on older DCS systems like MOD but this is due to generic issues with the DCS comms, not the OPC layer. )
However, Im not sure what the licensing status is when used in a system other than a QCS.
Otherwise, you're probably looking at 3rd party solutions Im afraid.
