Example 1: EGD Configuration Using IP Addresses to Identify Consumers
There are two PLCs in this simple EGD system. PLC1 is the producer and PLC2 is the consumer
of a single Ethernet Global Data exchange. The consumer in this example is identified by IP
address. Network-synchronized time stamping is not used. The identification of the PLCs and
the details of the exchange are shown in the tables below.
