By default is disabled.
When is enabled, the first four bytes of process data on the EtherNet/IP network contain the data exchange control.
The holds 32 bits.
Each bit in the can be used to enable/disable data exchange for individual nodes on the subnetwork.
If control bit does not correspond to a configured node, the control bit is ignored. For example, this occurs when the number of configured nodes is less than 32.
The node order in the 32 bit array always matches the Live List.
When the data exchange is enabled for the corresponding node, the control bit is 1.
