FIELD: physics, computer engineering.
SUBSTANCE: group of inventions relates to controlling a technological process using a handheld communicator. Disclosed is a handheld communicator for use in a technological process control system which comprises a controller connected to a field device having a processor; computer-readable memory having instructions read by a computer and executed in the processor; a touch screen and software stored in the computer-readable memory and configured to provide in the processor a user interface on the touch screen, having a portion for data transfer and placement, including a set of input fields scrolled by a mechanism for data transfer and placement; and a selection portion which includes at least one value associated with a corresponding input field from the set of input fields and displayed simultaneously with the data transfer and placement portion, wherein the selection portion is capable of scrolling through the data transfer and placement portion and is configured to receive from a user a selected separate value for a separate input field from the set of input fields in the data transfer and placement portion, and a scrolling operation associated with the data transfer and placement portion, is separated from a selection operation associated with the selection portion.
EFFECT: designing a handheld communicator with a sensor control interface with broad functional capabilities.
