6-32 Communicating with Devices on an EtherNet/IP Link
Example 2: Controller to
Controller
In the following example, one EtherNet/IP DriveLogix5730 controller
communicates with another EtherNet/IP DriveLogix5730 controller over
EtherNet/IP. Each controller has its own local I/O.
Producing and Consuming Tags
Produced data must be of DINT or REAL data type or an array or structure.
You can use a user-defined structure to group BOOL, SINT, and INT data to
be produced. You can produce a base, alias, or consumed tag.
The consumed tag must have the same data type as the produced tag in the
originating controller. The controller performs type checking to ensure
proper data is being received.
