I am trying to setup communications between an m580 and a compactlogix plc. I have confirmed my set up on schneider side is correct and now I am trying to troubleshoot the Allen Bradley side. The error I am getting is Configuration data size is too short. This is on a message block, CIP generic, Service type Get Attribute single, instance 101, class 4, attribute 3. I have added the 4 extra bytes required to my destination structure, and I have also tried using a significantly oversized array of 50bytes (I am reading 18) always getting this error.
