The BEMS (Building Energy Management System) is sold as an option to a WebAccess HMI & SCADA software package. It uses an additional Hardkey (a second Hardkey) installed on the Project Node. The hard key is a Sentinel SuperPro manufactured by Rainbow Technologies. The hard keys connect to the Project Node computer’s parallel or USB port.
The Hardkey serial number must match the serial number in the software license control file. The software license control file describes how many tags are in the license. You will need the Software License Control file during Installation of the SCADA node. The 'Control File" is usually distributed on a Floppy Diskette with your package. The "Control File" must match your Hardkey.
If user moves his Hardkey to another computer and does not move his license file, then BEMS will not run.
If the user wants to upgrade his WebAccess to include BEMS, he would purchase a new Hardkey and license file.
