Edwin,

Thank you for respond. I know about this example and I used it to get access to AssemblyObject class to read IO status of my drive. May be I am missing a point, but it looks for me that example is for common services (like setAttribute, getAttribute, Start, Stop, etc). In my case I have vendor specific profile with service code 0x3C and the class code is 0x64. I can enter class code in the function block even if it is not standard, but I don't understand how to use service code.
IIoDrvEIPAcyclicServicesLibrary with IoDrvOpenClass3Connection and IoDrvSendClass3ConnectedMessage methods is exactly what I needed (it has structure with service code, class code, Instance and Attribute), but yesterday I found out that that library is for Hilscher card only.

Thank you!

Hello,

I am using stepper drive that "supports Explicit Messaging using either a Class 3 connection or the Unconnected Message Manager (UCMM)". I had success to communicate with this drive using UDP, but can't figure out how to send and receive messages over Ethernet/IP using class 3 connection.
I found IIoDrvEIPAcyclicServicesLibrary in Library Manager that has IoDrvOpenClass3Connection and IoDrvSendClass3ConnectedMessage methods, but it is part of interface and I don't know how I can implement it and use it.

Do you have any suggestions?

Thank you!
