Driver and application support

The initial release of Niagara 4 supports most of the commonly used NiagaraAX drivers, including BACnet, LonWorks, Modbus, SNMP, and some legacy serial-based drivers. Support was dropped for a few drivers.

The following table lists a few drivers and applications that are no longer supported.

Unsupported driver / application

Removed modules / notes

802.1x wired authentication support for QNX-based JACE controllers

Module “platIEEE8021X”

OpenADR client drivers (simple, smart)

Modules “adr” and “dras”

Alarms to relational database support

Module “alarmRdb”. Superseded by module “alarmOrion”.
Note if a third-party application accesses alarms, it will be affected by this (change in the exported schema).

Original crypto/security module, using “CryptoService” in station

Module “crypto”—replaced by “platCrypto” since AX-3.7 (should only be used by non-Hotspot JACEs, for example,. JACE-2).

Dust wireless mesh network

Module “dust”

Energy Application System (EAS), also known by the branded name VES

Module “eas”

Support for FIPS 140-2 (Federal Information Processing Standard)

Special FIPS distribution (.dist) file

Floating license repository

Module “flr”

Fox tunneling, HTTP tunneling, and platform tunneling

Improved security in N4 prohibits most tunneling. Only serial tunneling is supported in Niagara 4, via the “tunnel” module on the station (server) side and a separate client-side tunnel application.

IBM DB2 relational database support

Module “rdbDb2”

Lon tunneling

Module “lontunnel”. Improved security in N4 prohibits this tunneling.

Sedona (SedonaNetwork, SedonaJen6lpNetwork)

Module “sedonaInstaller” in AX builds, which, from a downloaded Sedona “bundle,” would install Sedona-specific modules for integration. These are not supported.

Older video drivers based on the “devDriver”, superseded in AX by “nDriver” based videoDriver framework

Modules “video” (base), “axis”, “dedicatedMicros”, “milestone”, and “rapideye”, superseded in AX by modules “nvideo”, “naxisVideo”, “ndedicatedMicros”, “nmilestone”, and “nrapideye”.

Platform support for Niagara R2 on any QNX-based JACE controller

Niagara R2 platform support on JACE-603/JACE-645 controllers requires Workbench (3.6, 3.7, or 3.8).

 NOTE: This is a partial list. Other rarely-used or limited-distribution software modules were not brought forward to the new version. For more information, check with your support channel to verify availability. 

Additionally, any OEM-specific or custom (non- Tridium) software modules used on any platform to be migrated must be refactored for use in Niagara 4. This is a separate process from using the migration tool on a saved AX station, and must be completed by the custom module developer before you migrate the station.
