摘要 |
A system for wirelessly communicating between multiple devices of a process control system is disclosed. The system includes a basestation that communicates with multiple field units via a wireless signal and in accordance with a wireless protocol. The wireless protocol is made up of frames that are defined by multiple time slots, an initial one of which is reserved for a wireless start-frame message from the basestation to multiple field units. The base station utilizes the start-frame message to assign the remaining time slots to field units and to provide information to synchronizing the field units to the basestation.
