In order to convert the N4 controller to AX you must run a conversion distribution file that leaves the controller in an AX 'clean' state. At that point, you commission the unit via AX-3.8U1Workbench. This procedure describes the steps to convert the controller.
Prerequisites:
JACE-8000-AX feature added to a JACE-8000 license
N4.2 (or N4.1) and AX-3.8U1 releases licensed and installed on your PC Note, that you can use N4.1 but you must obtain the clean.dist file and manually copy it into the !conversion directory.
Perform the following steps:
In the N4Workbench, open a platform connection to the controller and click Distribution file Installer.
In the Distribution File Installer view, click Conversion.
A table displays a list of .dist files located in the !conversion directory.
Select the file: N4toAx-qnx-jace-titan-am335x-clean.dist, (as shown) and click Install:
CAUTION: If converting a JACE-8000 that has an existing Niagara 4 configuration, this data will be lost. This includes configuration, alarm and history information, server certificates, licenses,
and files.
On successful completion of the conversion, the controller is returned to a AX ‘clean’ state.
In AX-3.8U1Workbench, open a platform connection to the controller and click Platform Administration.
In the Platform Administration view, click Commissioning.
NOTE: For more information refer to the “Run the Commissioning Wizard” procedure in either the JACE NiagaraAX Install & Startup Guide or the NiagaraAX Platform Guide.
On commissioning completion, the controller reboots. At this point, you can reconnect to the platform using AX-3.8U1 and in the Platform Administration view confirm that the Baja Version is 3.8.xxx, as shown here.
