Hi, I’ve been working for a few weeks on an application that connects via socket through the primary interface with a CB3 robot (currently, i am using ursim 3.14). Now I am trying to receive “PopUpMessages”: int messageSize unsigned char messageType=MESSAGE\_TYPE\_ROBOT\_MESSAGE=20 uint64\_t timestamp char source char robotMessageType=ROBOT\_MESSAGE\_TYPE\_POPUP=2 unsigned int requestId unsigned int requestedType bool warning bool error bool blocking uint8\_t popupMessageTitleSize charArray popupMessageTitle charArray popupTextMessage I use the attached documents on [Remote Control Via TCP/IP - 16496](https://www.universal-robots.com/articles/ur/interface-communication/remote-control-via-tcpip/) to know the structure of each package. While trying to receive this type of package, I noticed that robotMessageType value of PopupMessage is 9 instead of 2. Is that possible? I know that there is another type of MESSAGE\_TYPE\_ROBOT\_MESSAGE that has robotMessageType = 9 (RequestValueMessage), but it isn’t this one, it is a PopupMessage, because i can get all the information of PopupMessages showed above. Maybe I am misunderstanding something related with the documentation, correct me if it is the case. Also, I would like to point that the ValueTypes in excel are not updated, while in the pdf file they are. Thank you for your time!
