Building Technologies "Energy indicator" function 28.08.2012
5.3.3 Estimated processing time
After starting the "Energy indicator" function, the "Plant" web page contains the fol-
lowing:
•
Summary display "Energy indicator"; see Section 5.2.6.
•
Number of monitored data points; see Section 5.2.4.
•
"Estimated processing time"; see below.
The "Estimated processing time" is displayed in hours and minutes.
When monitoring is active, the web server first reads each data point from the bus
devices and then compares the values to its "Green limit".
Processing time at base load per data point is 12 seconds (longer if the bus carries
a heavy load).
Thus, updating the "Energy indicator" (leaf color) display may take up to 40 min-
utes. Therefore:
• "Green leaf" (start-up mode)
The "Green leaf" display does not necessarily reflect the current plant state
prior to completion of the "Estimated processing time".
•
The updated display of "Energy indicator" can be postponed by max. the "Esti-
mated processing time".
Note the restriction from the "updated "Energy indicator" display" also when navi-
gating to other web pages.
5.3.4 Deactivating "Data point monitoring"
Monitoring "Energy indicator" data points is activated automatically following device
list creation.
Thus, data point monitoring can only be deactivated as a first step.
•
Deactivation for "Data point monitoring" requires "Administrator" access rights.
The checkbox in the "Energy indicator" column allows for deactivating monitoring
of one or multiple data points e.g. for operational reasons.
