1. A method comprising:
- receiving first data from different ones of multiple wireless field devices at a remote terminal unit, the first data received using different ones of multiple wireless communication protocols that are supported by a common transceiver;
executing control logic at the remote terminal unit to generate control signals for one or more actuator field devices using data from one or more sensor field devices in order to control at least part of an industrial process;
communicating second data to the wireless field devices from the remote terminal unit using the common transceiver, the second data transmitted using the different ones of the multiple wireless communication protocols; and
communicating at the remote terminal unit with a control system, the remote terminal unit at least partially controlled by the control system.

Abstract
A method includes receiving first data from multiple wireless field devices at a remote terminal unit. The first data is received using multiple wireless communication protocols. The method also includes executing control logic at the remote terminal unit in order to control at least part of an industrial process. The method further includes communicating second data to the wireless field devices from the remote terminal unit. The second data is transmitted using the multiple wireless communication protocols. In addition, the method includes communicating at the remote terminal unit with a control system, where the remote terminal unit is at least partially controlled by the control system.
