[closed] IEC 61850 MMS simulation

I've been studying the MMS protocol as a planning to implement a very simple write mms value function. In order to help my understanding I have tried to emulate to do the following: I am trying to simulate a write command using Hercules (TCP Client) and the SystemCorp MMS Server. I captured the packet between SystemCorp Client and Server connection using Wireshark, from TPKT up to the MMS, and used the packet in Hercules TCP Client to carry out the same action as I did while using SystemCorp Client, but the SystemCorp doesn't react in the same way. What should I change in this packet to emulate the SC Client using Hercules TCP Client. Thanks

Following is the packet I've been trying to send over Hercules TCP Client in order to change a item on the System Corp MM Server:
