Hi everyone, I'm facing an issue while connecting a Siemens S7-1500 PLC to Ignition SCADA, and I could really use some help from the community. After successfully connecting the PLC to Ignition using the Siemens S7 driver, manually created tag and its show a "Bad" quality status. Has anyone encountered a similar issue? Are there any specific settings or troubleshooting steps that might help resolve the "Bad" tag quality problem? I’ve attached some screenshots of my current configuration for better clarity. Thanks in advance for your suggestions and support! ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/c/4ce372115f7769e4f1a7cc0eb73e202f7266239b.png) gateway communication was successful ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/a/aa057a23de01c2863dbe144206bf1526fb4092fe.png) PLC Protection settings were already done ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/f/ef2d6fb8feae945c971867290d785101aaaf5deb.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/5/35baac7f1a30f1d8ca13ec6bc11608d5de6582fb.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/e/fe9bc7b74d19f29fbc2181526e5d7a27fde8126b.png) dear experts how to solve this? ---

`MI2.0` isn't valid Siemens address syntax. Try `MX2.0` - `X` is used for the datatype when you are trying to address a bit. You've also got a screenshot of a DB and its properties there but you aren't addressing anything in the DB. The tag in your screenshot would be something like `DB52,I2` or `DB52,X2.0` for the bit. Make sure that you have compiled and downloaded both software and hardware configuration for the protection and optimized block settings. > **[Siemens | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/opc-ua/opc-ua-drivers/siemens#address-syntax)** > > The Siemens drivers in Ignition support basic connections to S7 devices. Ignition connects to these PLCs via TCP/IP using the S7 protocol. Similar to Modbus and some Allen Bradley connections, the Siemens S7 devices do not support tag browsing. You... ---
