Issue Importing Structs/UDTs from Siemens TIA S7-1500 into Ignition 8.3 via OPC UA

Hi everyone,

I’m trying to connect my Siemens S7-1500 PLC to Ignition 8.3 via OPC UA.

When I browse the PLC’s DBs, I can see the Structs and any UDTs present.

The problem occurs when I try to import them: If I select the entire DB to import, Ignition only creates the macro area and generates a JSON that I cannot interpret/use properly.

In other words, I cannot correctly map the Structs and UDTs inside Ignition.

Does anyone know if there’s a proper way to:

  • Fully view Structs and UDTs from the PLC in Ignition?

  • Import them correctly without losing the internal - data structure?

Thanks in advance!

I'm not sure I fully understand what you're describing, could you provide screenshots?

Otherwise, you could try enabling "Deprecated Data Type Dictionary Support" for the OPC UA connection to the PLC. OPC UA Connections | Ignition User Manual
