Abstract: A system includes a control system and a Remote Terminal Unit (RTU). The control system is configured to communicate data with one or more field devices via the RTU. The RTU is configured to transmit received data from the one or more field devices and the control system. The RTU is also configured to activate a power saving mode that selectively provides power to transmit the received data. The RTU is further configured to, while the power saving mode is activated, prevent power from being provided to transmit the received data, and store the received data in a memory of the RTU when the power is not provided to transmit the received data. The RTU is configured to, while the power saving mode is activated, provide power to transmit the received data after storing the received data in the memory of the RTU.

Abstract: A method includes receiving inputs including a serial communication protocol specification and serial port settings associated with a serial communication channel. The method includes determining a transmission speed, a request size, and a response size of the serial communication channel based on the inputs. The method includes determining a timeout value corresponding to the serial communication channel based on the transmission speed, the request size, and the response size. The method includes automatically setting a timeout parameter for the serial communication using the determined timeout value. The timeout parameter defines a length of time between a start time of a transmission of a request through the serial communication channel and an end time of waiting to receive a response. The method includes in response to not receiving the response before the end time, determining that a first device is not connected to a second device through the serial communication channel.
