This feature enables the NRIO (Niagara Remote Input Output) driver, required to configure and use a JACE controller's Nrio-type I/O modules and/or any onboard I/O of a controller. All N4 JACE controllers support NRIO modules (which communicate via RS-485). Note that in the nrio features line (below), a “device” equates to an “Nrio16Module”, and that history and schedule limits have no practical application.
