Example 2: EGD Configuration Using a Group ID to Identify Consumers
There are three PLCs in this EGD system using the Group ID feature. PLC1 is the producer and
PLC2 and PLC3 are the consumers of a single Ethernet Global Data exchange. The consumers
in this example are identified by Group ID. Network-synchronized time stamping is not used.
The identification of the PLCs and the details of the exchange are shown in the tables below.
