Claim 8:
9. A method for communicating data over an industrial control network, the method comprising the steps of:
generating a first data packet for transmission over a connection in the industrial control network with a first producer, wherein the first data packet includes safety data and a connection identifier defining the connection for communication over the industrial control network;
generating a second data packet for transmission over the connection in the industrial control network with a second producer, wherein the second data packet includes the safety data and the connection identifier and wherein the connection identifier is generated by either the first producer or the second producer and the connection identifier is used by both the first producer and the second producer;
receiving at least one of the first data packet and the second data packet with a first consumer via the industrial control network;
extracting first safety data from either the first data packet or the second data packet received at the first consumer;
receiving at least one of the first data packet and the second data packet with a second consumer via the industrial control network,
extracting second safety data from either the first data packet or the second data packet received at the second consumer, wherein the first safety data and the second safety data are identical during a successful transmission; and
when the first safety data and the second safety data are different, entering a safe operating state with either the first consumer or the second consumer.
