Digital networking in a welding system

A method for handling a data packet in a welding system, comprising:

• receiving the data packet at a network device of a welding-related device;
• separating, by the network device, network layer data of the data packet from message data of the data packet, wherein the message data of the data packet comprises a message header and a message payload, the message header comprising:
• a source address represented by less than four bytes;
• a destination address represented by less than four bytes;
• and
• a format identifier indicative of a format of payload data of the message data;
• determining whether the destination address of the message data matches an address of the network device or whether the message data indicates a broadcast message;
• and
• handling the message data based on the determination.

A network device of a welding system comprising:

• a processor configured to form message data, the message data comprising a source address represented by less than four bytes, a destination address represented by less than four bytes, and a format identifier;
• and
• a network interface configured to:
• receive the message data from the processing device,
• combine the message data with network layer data to form a data packet, and
• provide the data packet to a second network device.

A welding system comprising:

• a first welding-related device having a first network device, the first network device configured to:
• combine message data with network layer data to form a data packet, the message data comprising a message payload and a message header, the message header comprising a source address represented by less than four bytes, a destination address represented by less than four bytes, and a format identifier, and
• transmit the data packet over a network medium;
• and
• a second welding-related device having a second network device, the second network device configured to:
• receive the data packet from the first network device;
• separate the network layer data from the message data,
• determine whether the destination address of the message header matches an address of the second network device or whether the message header indicates a broadcast message, and
• handle the message data based on the determination.
