Hello, I have a Tani OPC server connected to a Siemes PLC, here is a screenshot of what I see from the Ignition’s OPC browser:
I need to list the tags inside the AcMotors folder using the system.opc.browse function. I tried with this statement:
system.opc.browse(opcServer=‘Tani_OPC’, opcItemPath=‘ns=1;s=MAIN_PLC.DataBlocks.AcMotors.*’)
but the call raises a timeout exception after a while. The string “ns=1;s=MAIN_PLC.DataBlocks.AcMotors” is what I get from the OPC browser opction “copy item path”.
The syntax should be correct, because a similar statement works on the Ignition OPC UA Server:
system.opc.browse(opcServer=“Ignition OPC UA Server”, opcItemPath=“ns=1;s=VendorServerInfo.*”)
so why it doesn’t work on the Tani OPC? I would try to use browseServer, but how to format the nodeId parameter in my specific case?
Many thanks in advance,
Francesco
