Hello,

I use Siemens PLC S-1500 with firmware version 1.8 (which doesn’t support OPC UA server feature with this firmware version) and tried to connect it with Ignition.

The Ignition could connect to the port 102 of IP address for S-1500. ( Enable the port 102 by setting the Win10 firewall)

I use the instruction as shown in below link to set the PLC project to enable the remote connect and un-check the optimization of global DB.  
[https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/29/0/connecting-to-siemens-s7-1200-and-s7-1500](https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/29/0/connecting-to-siemens-s7-1200-and-s7-1500).

But it only display the diagnostics info of PLC as shown in below snapshot. None of PLC tags could be displayed.

I also found some error log info

Anyone could help about it?

Thanks in advance.

You have to manually specify the tags…

For anyone stumbling upon this post in their search like I did, the relevant link in the new documentation is [here.](https://www.docs.inductiveautomation.com/docs/8.1/ignition-modules/opc-ua/opc-ua-drivers/siemens)

And for completion's sake; if you're working with S7-1200 or S7-1500, make sure 'optimized block access' in the properties of the Siemens DB you're trying to acces is **disabled** , and 'permit access with PUT/GET communication from remote partner' in the PLC's hardware configuration is **enabled**. You can find this last one under 'Protection and Security'.
