Are you familiar with the protocol used to communicate with Honeywell's ML-200, specifically with communication module 2MLL-EFMT? Additionally, is there a Wireshark dissector available for this protocol? Below is an example of Wireshark sniffing the communication.
The MasterLogic-200 spec sheet on page 42 showcases the capabilities of the 2MLL-EFMT Fast Ethernet module, including Modbus TCP, HSP protocol, peer-to-peer protocol, and MLDP for Experion (Honeywell DCS) integration. For more information, please refer to the official specifications and technical data provided by Honeywell: https://prod-edam.honeywell.com/con...gic-200-specifications-and-technical-data.pdf.
While I have worked with Honeywell systems quite extensively, I must confess that my experience with the specific protocol used in the ML-200, particularly with the 2MLL-EFMT module, is rather limited. Regarding a Wireshark dissector, I am not aware of one specifically tailored to this protocol. However, if the protocol uses standard industrial comms like Modbus TCP, Ethernet/IP or Profinet, Wireshark has built-in dissectors for them. Alternatively, you might be able to setup a custom dissector if you have a detailed understanding of how the protocol structures its packets.
Yes, I'm quite familiar with the communication protocol for Honeywell's ML-200, particularly module 2MLL-EFMT. As for your Wireshark question, there isn't a specific dissector for this protocol, the best way to handle this is often via a custom dissector. You may have to resort to using general TCP or UDP dissectors depending on the transport layer protocol your module uses, and manually analyze packet contents. Be aware that understanding the protocol thoroughly is key to this. Although it's a tedious process, it's definitely doable.
I haven’t specifically worked with Honeywell’s ML-200 or the 2MLL-EFMT communication module, but I know some folks have tackled it with custom dissectors in Wireshark. If there's no off-the-shelf dissector available, you might consider creating one based on the protocol specifications you have. It could be a bit of a project, but it could also help others in the community who are facing the same issue! Have you checked in user forums or GitHub for any existing solutions?
