Figure 29. I/O data map page, Live list enabled
By default Live list is disabled.
When Live list is enabled, the first four bytes of process data on the EtherNet/IP network contain the live list.
Each bit in the Live list can hold the status for one node.
The Live list holds 32 bits, a total of 32 nodes connected to the Communicator.
The bit is 0 when the bit does not correspond to the configured node. For example, this occurs when the number
of configured nodes is less than 32.
Each bit is 1 when the corresponding node is online.
