I would ask you a clarification about tags.
I’ve two gateways that realize an “Hub&Spoke” Cloud architecture. The first one is on the field (Plant GW) and has only the OPC-UA and SQL modules, while the second is fully licensed and it is on the Cloud (Cloud GW). The Plant GW collects data from the field, then push the historical data (Store&Forward) on the remote DB on the cloud. The Cloud GW read the field data from the plant GW (via OPC Connection) and provide all the main features (graphical pages, ecc).
The tags are configured as follow: on the Plant GW I’ve defined the required UDTs and instanciated all the SQL tags. In the UDT I configured also the tag properties (eng unit, etc.).
On the CLoud GW, in order to display the real time data, I opened the OPC browser, then drag&dropped the tag from the plant gateway.
On the cloud gw I noticed two main issues:
- The UDT structure is lost and then tags are grouped by folders
- Also the properties, defined in the UDT on the plant gw, are lost
The two issues above imply that I’ve to manually reconfigure every tag of every instance since UDT are no more present… about 8000 tags… I know that I can select multiples tags and reconfigure them in “one shot”, but the structure is quite nested and it is very difficult to do this for every “family”… Another way could be to export the tags and modify the csv/xml file, but I’m afraid that it will be a pain anyway…
Since this is a nightmare, I would ask you how I could reconfigure the (cloud) tags properties in a smarter way (or if I have to modify my approach)…
I hope that my explanation is clear… If not, don’t hesitate to let me know.
