Abstract

A method and interface for automated loop checking of an industrial process control and automation system comprises importing wiring diagrams and alarm setpoints to operating software executing on a hand-held device from a database. The operating software uses the wiring diagrams and alarm setpoints to build an I/O loop check file. The method further includes, installing a dongle adapted to simulate I/O signals on a first terminal block. The dongle making an electrical connection to at least one I/O loop. The method further includes transmitting via a communication link the I/O loop check file to the dongle and instructing the dongle to perform an I/O loop test on the at least one I/O loop by simulating I/O signals based on the I/O loop check file. The results of the I/O loop test is transmitted via the communication link the results to the operating software.
