In Triggered Sampling an application (e.g., via data flow interconnection)
determines when values are acquired/logged and saved. Triggered Sampling is
supported by the Trendlog object and the Trendlog Multiple object.
11.2 Editing parameters
Many of the parameters in the trend log object are definable only if:
● Enable for logging (Enable logging) [EnLog] is
inactive
● The log buffer is empty (Record count = 1)
In this state, the following variables can be modified:
– Start time [TiStt] and stop time [TiStp]
– Interval [Ivl]
– Buffer size [BufSize]
– Record count [RecCnt] (can only be overwritten with 0: delete log
buffer)
– Notification threshold [NotifThd]
– Input/Output address [IOAddr] (if an unavailable BACnet address is
entered, an alarm is initiated)
● [EnLog] is
inactive or active
● The log buffer is not empty (log count > 1)
