9.2.2 Restriction to bus load
Bus load by the trend function is restricted to 1 data point per second
(corresponding to 100 %). The sum of the loads of all 5 trend channels cannot
exceed this value.
No new trends can be started once the value is reached.
In the example below, the query interval of the outside temperature of 1 second
already results in a bus load of 100 %. As a consequence, an additional query of
the room temperature at 50 % load can no longer be started.
Any attempt to start this trend results in a warning.
9.2.3 Reset trend definition
Trends can be reset to the default settings.
The default settings for the values are as follows:
– Interval = 15 Min
– Number of data points = 0
– Status = Invalid
– History window = ? days
– Bus load = 0 %
– Trend name = ""
Any associated trend data is deleted when the trend definition is reset.
1. Click the red waste can symbol
The confirmation window Delete of the trend data opens.
2.
Confirm delete of trend data with OK.
The trend settings and data is deleted.
