A system, apparatuses, and methods support simultaneous connectivity between devices in an industrial control and automation or other system. For example, a data publisher can publish or provide data to multiple data subscribers. This can be done using a multicast group associated with the multiple data subscribers. The data publisher transmits a data message using a network address associated with the multicast group. Each data subscriber associated with the multicast group receives a copy of the data message. As a particular example, the data publisher could represent a wireless sensor or wireless actuator in the industrial control and automation or other system. Also, the data subscribers could represent multiple controllers or actuators in the industrial control and automation or other system. In this way, the multicasting functionality allows for simpler connectivity or interaction between devices in the industrial control and automation or other system.
