The Nrio Device Manager has an Upgrade Firmware button. It is available when you select one or more NrioModules that have older IO processor firmware (than what is inside the JACE’s nrio module).

Control may be briefly affected during an IO firmware upgrade. Before starting a firmware upgrade, it is recommended to put associated controlled loads in a manually-controlled state. A firmware upgrade typically takes less than one minute for each NrioModule. After the firmware upgrade, controlled loads may be safely returned to system control.Also, ensure that power (and communications) to the JACE and IO is uninterrupted during the upgrade.

When you click Upgrade Firmware, an associated job is sent to the station’s JobService, where upon job competition you can see the step results. An NrioModule upgrade firmware job typically takes less than 1 minute, during which time the NrioModule briefly goes offline and the IO firmware file is downloaded from the JACE.

Following the upgrade, notice that the “installed version” and “available version” numbers match, and the Upgrade Firmware button is no longer available when the NrioModule is selected (Figure 12).

Note also that device “Ping” alarms typically result from an IO firmware upgrade—from when the NrioModule(s) toggled offline and back online.
