My problem is that I receive integers via OPC UA and I would like to display these integers with a decimal part in MappView. Example: I receive the position 156964 and I would like to display 1569.64. Is there a trick for this? ---

HI Romain, you could use unit conversion. How it works is descriped in here: [B&R Online Help (br-automation.com)](https://help.br-automation.com/#/en/4/unitsystem%2Ftranslationformulas.html) Define an own unit for your output and assign it to the NumericOutput widget. Don’t forget to use NodeBinding. 🙂 ---

Hi Simon, Thank you very much for your response! Unfortunately, this solution does not work. I tried to implement it this afternoon. I can subtract 10 from my variable by setting 10 for the variable n, but I must admit that I don’t quite understand. Which formula is used? The normal or the inverted one? ^^ In my case, I want to divide by 10, but none of the attempts were successful. For your information, the OPC UA variables come from a SIEMENS PLC that I have declared in OpcUaServer. And if I understand correctly, this method will only work for a display, right? Because I also have numeric inputs to process. I need to type 15.6 on the keyboard, and the OPC UA value should be equal to 156. Thank you for your time. ---

Salut Romain, first of all you have to define a unit translation: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/7/71541bd44ef52844f258fbcf315471d845a7a079.png) I used some fake units. You can also define your own units. In next step you have to set input unit to your OpcUa value. I did this in Automation Studio. Don’t know how to do this for Siemens OpcUaServer: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/0/08343c29038fd14dc0a8635a963554ecfda7acc1.png) Last step is to do a node binding in mappView and select right output unit and translation formula: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/8/8a11c679127cd6b9321db31e2f5437b7db4e1724.png) As result I got this: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/2/28702324e67e721313c0e826af0d6dbc3214095c.png) Maybe there is a possibility to do this without any (fake) units. But I don’t know how to do this. Hope, this is a solution for you and also works with Siemens OpcUaServer. ---

I marked reply from @Simon_Stoll as a solution.
