Siemens S7-1200 OPC Help

Hey everyone, first post, so thanks for the help. I am following the manual for adding a Siemens OPC driver and cannot get the tags to communicate. The PLC OPC driver is connected. I have double-checked the address string. I did the most recent firmware update for the PLC. The tag is OPC enabled. Below are screenshots. Please let me know anything I am missing or if the OPC driver just isn’t working. Thanks.

Just guessing, but your tag name is TestInt and in Ignition you used IW0 instead.

What does the diagnostics tab for the Ignition tag say, if anything?

You may want to check

General>Protection & Security>Connection mechanisms

Are there any errors in your logs on the gateway?

This was the correct answer. Thanks everyone!

No, it was the checkbox in TIA Portal. Thanks for your help.

There’s a couple other limitations to be aware of: https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/29/0/connecting-to-siemens-s7-1200-and-s7-1500

Very good to know. Thanks.
