Machine to Machine Communication
The Machine to Machine (M2M) communication feature allows communication and data exchange between devices or machines without the need for human intervention. This means that machines can communicate with each other, share information, and make decisions based on that information without human assistance.
The secure M2M communication feature available in the IFE interface enables the protection of Modbus TCP communication by ensuring its confidentiality. When this feature is activated through the IFE webpages, the communication between a Modbus TCP client and the IFE interface is encrypted using the TLS protocol on port number 802. For information about enabling secure Modbus for M2M on the IFE webpages, refer to IP Network Services Parameter .
