ABB OPC HDA client is not browsing the values more than 500 signals
I need the urgent help for this issue. We are having the Siemens SPPA-T3000 DCS as OPC Server and ABB as OPC client. It has observed that the ABB HDA client can not fetch the values more than 500 from the SPPA-T3000 system.
SPPA-T3000 expert team has checked and no such limitations are mentioned there as well as they have checked with other cient also and it can browse further. Do we have any other ABB OPC HDA client tool taht can run directly to check the signals more than 500.
Pleas help urgently.
There are a few questions that I would first ask.
1) Are they connected to the proper OPC server in the 800xA system to gather this data?
They should be utilizing the following connections.
2) What application are they utilizing for the connection?
3) DataDirect can be utilized to perform these tasks. However, the OPCHDA connection in DataDirect can only be utilized from a node within the 800xA system, but it would provide verification of the function. If you do use DataDirect, (Excel), be sure to alter the default returned values setting to greater than 500.
4) Another option is to test with Matrikons OPC Client, which can be downloaded from their website. I have attached a demo I did of this product.
Let me know if this helps.
