US 2023/0361980 A1 · EVENT DEVICE SYSTEM OPERATION

Abstract

Devices, systems, and methods for event device system operation are described herein. In some examples, one or more embodiments include a controller comprising a memory and a processor to execute instructions stored in the memory to transmit, to a plurality of event devices via a power line communications (PLC) protocol, a synchronization message according to a predetermined schedule to cause the plurality of event devices to synchronize timing of the plurality of event devices with the controller, transmit, to the plurality of event devices via the PLC protocol, a command according to the predetermined schedule, and receive, from the plurality of event devices via the PLC protocol, a response to the command according to the predetermined schedule.
