OPC Connection to Siemens

Hello everyone,

I want to read data from a Siemens S7-1512 PLC using an OPC-UA connection directly to the PLC.

The connection in Ignition is working:

I can browse inside the server. I can read data like the serial number of the CPU. But I cannot find a way to browse inside the tags...

Can anyone help?

Thanks.

Hi @vrautomation,
You should have something like that


Verify that those two options are enabled in your hardware configuration

We enabled the options you shown but can't find any relevant data in the server.

Can you tell me where to find the data? I feel like I expant everything...

Make sure you compile and download software/hardware changes. I haven't had much luck making OPC UA configuration changes online.

We did it. No luck...

You should see it under here


Make sure of the following also:

Ok we will try this tomorrow.
Thanks a lot :slight_smile:
