Hi, Yes, it is possible to register methods in the Data Layer. You can see a example, if you go to "diagnosis/confirm/error" in the Data Layer. That this node is a method is defined in its metadata (Node Class = Method). If you click the button "Write" of a method, the code at your onWrite() function gets called. But I don't know if methods in the Data Layer suits your task. Could you please go into a little more detail on what you want to do in your Python App and what you want to do from the PLC? Best regards Nick

Hello Daniel, thank you for your answer! Code examples would be great to understand and recreate the issues as a whole. Best regards Nick

Hello Daniel, What do you mean by "the python SDK keeps crashing"? Could you give us some details on your troubles? Regards Nick

Please have a look at the variable "_connectionClient" (line 22 of datalayerclient.h) This connection string defines a tcp connection to the Data Layer of the localhost of the control. It contains the username and the password of the control (both "boschrexroth"). This connection only works at your control without any changes, if you use the same password and username. If you have a different username or password, you can either change the default "boschrexroth:boschrexroth" of the tcp string to your username and password. Or you can use the connection with DL_IPC_AUTO, then you don't have to worry about usernames or passwords. std::string _connectionClient = DL_IPC_AUTO; Here you can access further information about the connection types of clients (and providers).

Hello, the samples work fine for me, on ctrlX CORE and ctrlX COREvirtual. Have you installed the sdk-cpp-alldata sample first? And are you sure your CORE is in operation mode? Please have a look at Apps and check if you can switch to Operation mode. If you can see the possibility to switch to service mode, your CORE is in Operation mode. On the other hand, if the button says "Operation mode" your control is in service mode. Best regards, Nick
