Abstract: In aspects, the present invention discloses a method for communicating with a plurality of field devices using a remote terminal unit. The plurality of field devices includes a first set of field devices and a second set of field devices capable of communicating using a first and second wireless communication protocols respectively. The method comprises scanning for a beacon message from a first field device, determining a corresponding wireless communication protocol associated from the first field device, identifying a first set of configuration blocks for communicating with the first field device based on a configuration schema file and the corresponding wireless communication protocol of the first field device, and building a protocol stack for use with a radio front end from the one or more radio front ends using the first set of configuration blocks, for communicating with the first field device from the plurality of field devices.

Abstract: The present invention provides a method for time synchronizing one or more devices in a control network using a first device. The method comprises selecting a first device from information of the topology of the control network. The method further comprises sending a first set of packets to the second device, receiving a first set of delay requests in response to the first set of packets, and sending a first set of delay responses in response to the first set of delay requests. The method further comprises, determining a first set of forward times and first set of backward times. The method further comprises, determining a first minimum forward time and a first minimum backward time. Further the method comprises determining a first correction factor. The method also comprises, applying the first correction factor to a clock provided at the second device and storing the first correction factor.
