ABB continually reviews all Harmony Rack modules to ensure module manufacturability to sustain control functions in installed systems. This program has resulted in the redesign of most of the Harmony rack modules over the past several years to include modern technology and updated surface mounts for increased reliability. It includes the following Harmony Rack control network modules:
- NIS/NPM
Supports Plantloop or INFI-Net
Allows users to incrementally upgrade from Plantloop to INFI-NET one PCU at a time.
- INFI-Net to INFI-Net Gateways
Local and remote versions available.
- INFI-Net to Plantloop Gateways
All have fit, form and functional equivalent to Network 90, INFI 90, INFI 90 OPEN and previous discrete component versions of Harmony communication modules, racks and gateways.
