Hello, Please I’m Trying to add ABB 266AST DTM to x20CP0483 with x20AI2438. I’m using automation studio V4.12.2.93 I’ve installed the DTM and when I add it it gives me the below error: Error Connecting DTM device ‘ABB\_266\_PdP\_HART’. (The Persistency operation InvokePersistSave() failed!) A photo from automation studio is attached Thanks ![HARTProblem](https://europe1.discourse-cdn.com/brcommunity/original/2X/b/bd9568c01a530e6e10c9b366732ad367aa4d52dc.png) ---

Hello Kareem, I’ve seen a similar error from another customer. Please try upgrading to the latest version of Automation Studio v4.12. For a quick test, you can install the AS Service Pack for v4.12. **5**. To upgrade to the latest service pack of AS v4.12. **6** , you will need to uninstall your current Automation Studio version and perform the full reinstallation. AS v4.12.6: [Automation Studio V4.12 | B&R Industrial Automation](https://www.br-automation.com/en/downloads/software/automation-studio/automation-studio-412/automation-studio-v412/) AS v4.12.5 SP: [V4.12 AS Upgrade (4.12.5.95\_SP) | B&R Industrial Automation](https://www.br-automation.com/en/downloads/software/automation-studio/automation-studio-412/v412-as-upgrade-412595-sp/) (Also available through Tools \> Downloads) If the issue persists, please provide an updated full screen screenshot of Automation Studio when the error occurs. -Austin ---

Hello Austin, Thanks for your response. I’ve tried to both AS v4.12.5 SP and AS 4.12.6, but unfortunately the error still the same. I can’t add the DTM file of ABB to the x20AI2438 module. Below is a full screen shots of the automation studio. Note: The DTM file is downloaded form ABB official website. ![HART Error](https://europe1.discourse-cdn.com/brcommunity/original/2X/4/478456a489ba80268321d59056ad8b3a2e9af261.png) ![HART Error2](https://europe1.discourse-cdn.com/brcommunity/original/2X/1/1b38d3f9ae29169eaaf479791bdedf5a5d10d269.png) Kareem ---

Hello Kareem, It looks like a different cause than what I have seen earlier. I don’t believe the HART files from ABB are the issue, and I’m leaning more towards an Automation Studio issue. The next step is to contact your local B&R support office and start a support ticket with the information provided in this post.
