Hello, As the subject says, I'm trying to connect and 'talk' with a motor controller from festo (CMMO-ST-C5-1-DIOP). I'm using the TCP protocol, and am supposed to send bytes to the controller. While I'm sure the connection to the controller is established, I'm completely at a loss if I'm sending instructions in the right format. This document show examples on how to issue commands to the controller and read responses, but I don't understand what format to use. For example, the document states: So the following bytes have to be sent to the CMMO via Ethernet (in Hex): 10 04 00 00 00 04 00 00 00 00 00 00 00 00 06 00 03 00 The connection is obtained, but however I format the above bytes, I get no response from the controller. I have included the simple VI I'm using to send/receive the TCP instructions, and would greatly appreciate any suggestions on how to format my message. Any other ideas or suggestions are welcome as well - I need all the help I can get 😉 All I really want, is to get some kind of response from the controller - even an error would be great. Thanks, Tobias
