This feature enables the NRIO ( Niagara Remote Input Output) driver, required to configure and use the JACE controller's Nrio-type I/O modules and/or any onboard I/O of a controller. Most QNX-based 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.
