Hello! PLC transmits tags via CoDeSysOPCDA, getway ignition sees them, but the project stopped working and returns the main COMSubscrition error. OPC server returns an error code. I configured DCOM on Windows according to your instructions, but it didn't help. Maybe the problem is in the project tags? I'm a newbie and I don't understand, if I drag them from the tag browser to the project, where should I drag them and what should I do to make them work? How can I check that they work? Everything worked fine before. OPC Tunneler doesn't help. Please help me start the project. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/a/3ace1b073b2797a355f60452f4bd481f53502e19.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/b/eba7cdbe8900b7ecb1b0af52cbb7143b629a834e.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/e/8eff17df78f94c59e22c18f38c2efaaa653a61e1.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/4/e48f22e7a1991b33acdcb536109f2a22e4981ec5.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/4/448b5d74511730dee6806fa04623d78c3378fb0b.jpeg) ---

Your post and images don't mention MySQL. Why have you mentioned it in the question title? ---

The control program gives an error in SQL. The MySQL database is connected, works and accepts requests from Ignition SCADA. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/f/cf2649cc7752c2350f97106155ab48834b5d7255.jpeg) ---

Can you check the Gateway logs (under the Status tab) to see if there are any issues mentioned there? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/f/3f8a45298b7a16dd982bde967f4d197686a4eefa.png) ---

I have Ignition SCADA 7.4.7 There is a log from the console. When I click on the controls, errors with different numbers appear. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/3/e3cacd6990527d60462367f8a34b0ca3fd7d4320.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/3/138eaaa6e4e23676c9701ad056c8eab6b293b22b.jpeg) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/6/c6577053e1621d98afd5c35bbb3dea01cb9a5804.jpeg) ---

When you post errors and code, copy/type them in text to make it easier to read on the forum. Screenshots are helpful at times, but often make things harder. Also, format the errors with the formatting button. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/a/1a95621a03d3445bca4a44494a8d5c4da9c3f287.png) ---

And rotate the images the right way. Screenshots taken on the computer would be better. Make it easy to help you. ---

Thank you, I will definitely take screenshots. I am not at work now, I only have these photos.
