Hello,

yes Property Transfer is the aspect you normally use, when you eg want to write values to or from controller with thirdparty OPC data.

Don't execute too often....

To setup the Property transfer, use the following procedure:
Log in as System Administrator.
Go to the Service Structure in Plant Explorer.
Create a Service Group under the Property Transfer service.
Enter the Service provider name and click on create.
Select the Service Group object and its Service Group Definition aspect
Select the Configuration tab.
Click the Add button to add a provider and enter a Name

• Select the following under “Property Definition Aspect”
• Select “Application” under Aspect Column.
• Select the corresponding variable which is defined in application level.
Write the Expression which corresponds to the Tag available
• Syntax : $’Object:Aspect:Property’
• Write Substitution Value also can be set to some value which is used to transfer the same value when the Source Expression results in “Bad Quality”
Select the “Verify” Option available in “Property Definition Aspect” for verifying whether the Expression mentioned has no Errors and also give the required update rate.

thanks for your detailed procedure.. This is already done and I able to read the values to controller, But I need to write to some spare variables created in third party opc system. these also I did in the same way. but the value writing is not updating to their system.
while writing through advdsopcclient it is updating in their system

Only good quality values will be transferred.

Turn on OPC Communicator Common applog to monitor what is received and transmitted by AfwPropertyTransfer.exe service.

OPC write performance is poor in most OPC servers

afwapplogviewer.exe
Select server node
Select afwpropertytransfer process
Select OPC Communicator Common log
Set level 3
Click Get Messages
Save output to text file
Examine ”input”, ”output” and ”write response”
Reduce number of active transfers to make logging less voluminous.
email me the entire log (and list of active transfers) and I will comment on it: stefan dot stromqvist at se dot abb dot com

Hello,
I'm also interesed in such solution using generic opc network . In this scenario 800xA acts as OPC client (OPC Connects service) and has possibility to wrtie live data to Third Party OPC Server. In my project we need to transfer values of 30 points to external system, so I believe that this is the best solution.
ABB manual https://library.e.abb.com/public/40dfb2533af14dbe8d7b4d3e8c3d2c87/3BDS011222-600_C_en_System_800xA_6.0_Configuration.pdf descibes this starting from page 509, section Integrating OPC Servers into 800xA, but there are some points that are not clear for me.
After configuring all DCOM settings (OPC Server on non-system node) and Generic OPC Server Netowrk object creation is Upload action needed? Manual describes Upload action as :
"By uploading you collect all the objects in the OPC Server and append them as aspect objects in Control Structure" but I don't think this is what I need.
My concern is how to map points/tags from 800xA to existing tags on Third Party OPC Server?

Thank you for your comments
