• The Human Machine Interface (HMI) is connected to the PLC and the Internet via the building’s Internet or if not available at the HMI location, through a dedicated cellular modem. The HMI has a 7” high‑resolution color touch-screen that allows viewing and limited control of the entire CW system operation.
• The Notification feature alerts the appropriate responders depending upon the problem at hand. A ‘Notification Matrix’ spreadsheet will be developed for management to determine who should be automatically notified by the HMI for each different kind of problem or equipment failure so that the correct persons are notified and others are not bothered with nuisance notifications.
• The HMI screen is remotely viewable and accessible from off-site through both a free smart phone app and a free viewing program for computers.
