Claim 16:
17. A method for communicating data over an industrial control network, the method comprising the steps of:
generating a safety data packet for transmission over a connection in the industrial control network with a first producer and a second producer at a first time interval, wherein the safety data packet includes a connection identifier and safety data, the connection identifier defines the connection for communication over the industrial control network, and 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;
generating a time coordination data packet for transmission over the connection in the industrial control network with the first producer and the second producer at a second time interval, wherein the second time interval is greater than the first time interval and wherein the time coordination data packet includes the connection identifier and a time update request;
receiving the safety data packet with a first consumer and a second consumer via the industrial control network at the first time interval;
extracting the safety data from the safety data packet with the first consumer and the second consumer at the first time interval;
receiving the time update request with the first consumer and the second consumer via the industrial control network at the second time interval;
generating a time coordination response data packet for transmission over the connection in the industrial control network with the first consumer and the second consumer at the second time interval; and
transmitting the time coordination response data packet from the first consumer and the second consumer to the first producer and the second producer.
