Thanks for your reply 🙂 Your IndraDrive is connected to a ctrlX CORE via Ethercat and EoE is active? -- Yes, IndraDrive is connected to a CtrlX Core via Ethernet. The communication is working well. You are using the EAL library to talk to the drive? -- Exactly. In detail, i want to use the drives Oscilloscope function to read data. To activate it, a few parameters must be set before reading the data. The IParameter.WriteData() Method works fine when it comes to setting integer values, like for P-0-0020. I used the Method multiple times and it worked. The only problem is: I don't know how to use the Method to set an IDN (for example for P-0-0023). Which data format must be used? Where is the EAL running? is it on your PC or did you pack it in a snap? -- The C# program is packed in a snap and running on the CtrlX Core. Summary: The whole setup is working well. Using IParameter.WriteData and IParameter.ReadData are working well with binary or decimal variables. The only thing I can't do is to use the IParameter.WriteData Method() to set an IDN, for example for P-0-0023. The documentation says, the input is of type "IDN" with a length of "4Byte". How does a format of 'IDN' looks like in C#? Here are the documentations: Thanks a lot for your help!
