Node-RED Obix Niagara Connector:

ENSURE README IS FOR CORRECT VERSION OF INSTALLED PACKAGE

Links Node-RED to a Niagara Station through the Obix Protocol.

• Can read and write ('out' and 'set' slots) to control points under Drivers (in the Niagara Tree)
• Can GET or POST in the Niagara Tree and return as JSON
• Can read histories
• Can setup watchers which poll several points at a time on an interval

Obix - Niagara Setup:

To set up Obix in Niagara...

1. Open the obixDriver module from the palette.
2. Drag in the Obix Network (from the palette) into the station's driver folder.
3. Open the baja module from the palette.
4. Insert the HTTPBasicScheme (baja -> AuthenticationSchemes -> WebServicesSchemes) into the Authentication Service in the Services folder (Config -> Services -> AuthenticationService -> Authentication Schemes).
5. Create a new user with an assigned role (role must have correct permissions to read/write to any points or histories), and select the HTTPBasicScheme for the Authentication Scheme Name.
   • It is recommended to enable Auto Logoff with a short time period, or disabling Allow Concurrent Sessions, to reduce the amount of obix sessions Niagara has to manage.
