Issue
The user of OpenLDV and Echelon U10 USB adapters with their Engineering Laptops are concerned that Niagara 4.9 does not have a 32-bit installation option.
Product Line
TAC IA Series
Environment
- I/A Series N4 4.9 and later
- Windows 10 64 bit
Cause
OpenLDV 5 runs as a 32-bit application on both 64-bit and 32-bit versions of Windows. It cannot be called from a 64-bit client application. In order to use OpenLDV on 64-bit Windows, the OpenLDV client application must be compiled and run as a 32-bit application. Prior to Niagara 4.9, some customers used the Niagara 32-bit installer exclusively, which no longer exists, so that they could use OpenLDV.
Resolution
The 64-bit Niagara 4.9 Windows install includes a 32-bit daemon application that, without any extra configuration, provides a bridge between 64-bit Niagara and 32-bit OpenLDV. This means that technically, the Echelon U10 USB adapter should work in 64-bit Niagara version 4.9 and newer, on a Windows host (Tridium cannot guarantee operation). There is no longer a need to install 32-bit Niagara, and in fact, it is no longer available.
