BACS and communication via the Webmanager
Software and functional scope:
As a rule the CS121 chip takes precedent over the entire
functionality of the core GX module. The CS121 chip
essentially handles administration in the same way as the
classic USV CS121 SNMP web adapter, the difference
being that a BACS system is monitored in this case.
The web browser displays a warning (yellow) for
batteries that are weak or about to fail. As soon as a
certain threshold value is crossed, the symbol turns red
and a system alarm is activated (acoustically and via the
network, e.g. as an e-mail).
The web browser is also used to set the battery
parameters to adapt each module to the specics of the
battery manufacturer.
For the graphical evaluation of the data, either a custom
EXCEL le can be created or the user can use the
BACS VIEWER, an external Windows program that can
read the data across the network and display them gra-
phically. BACS VIEWER is available as freeware.
