1. A system of communicating data over an industrial control network, the system comprising:
a first producer configured to generate a first data packet for transmission over a connection in the industrial control network, wherein the first data packet includes safety data and a connection identifier defining the connection for communication in the system;
a second producer configured to generate a second data packet for transmission over the connection in the industrial control network, 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;
a first consumer configured to receive the first data packet and the second data packet via the industrial control network; and
a second consumer configured to receive the first data packet and the second data packet via the industrial control network, wherein:
the first consumer and the second consumer both receive one of the first data packet and the second data packet,
the first consumer extracts first safety data from either the first data packet or the second data packet which was received,
the second consumer extracts second safety data from either the first data packet or the second data packet which was received,
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, at least one of the first consumer and the second consumer cause the system to enter a safe operating state.
