Abstract

A method for conducting a partial stroke test of an emergency shutdown valve includes receiving a request to initiate the partial stroke test from a user interface or another source, establishing a direct or an indirect wireless communication link with the emergency shutdown valve, and generating one or more commands of a digital industrial automation protocol to be transmitted to the emergency shutdown valve via the wireless communication link, so that a partial stroke test of the emergency shutdown valve is initiated in response to these commands.
