Machine to Machine Communication

M2M Definition

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 server 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 server 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.

NOTE: For secure M2M communication to work, the Modbus TCP client must also support the Modbus TCP over TLS. If the client does not support this, then the standard Modbus TCP on port 502 must be used instead.
