Description Definition of the logging interval t
log
for data logging. This defines the interval between
the individual data points in the data log, and thus the maximum loggable process time
T
log
.
• If 1 logging channel is used: T
log
= 500 ⋅ t
log
• If 2 logging channels are used: T
log
= 250 ⋅ t
log
• If 3 logging channels are used: T
log
= 166 ⋅ t
log
• If 4 logging channels are used: T
log
= 125 ⋅ t
log
Once this time elapses, the oldest data points in the data log are cyclically overwritten such
that a time of T
log
always remains in the meory (ring memory principle).
Nach Ablauf dieser Zeit werden die ältesten im Speicher vorhandenen Datenpunkte
zyklisch überschrieben, so dass immer eine Zeit von T
log
im Speicher bleibt (Ringspeicher-
Prinzip).
The log contents are cleared if the length of the logging interval is changed.
Input range 1 to 3600 s
Factory setting 10 s
Additional information Example
If 1 logging channel is used:
• T
log
= 500 ⋅ 1 s = 500 s ≈ 8.5 min
• T
log
= 500 ⋅ 10 s = 5 000 s ≈ 1.5 h
• T
log
= 500 ⋅ 80 s = 40 000 s ≈ 11 h
• T
log
= 500 ⋅ 3 600 s = 1 800 000 s ≈ 20 d
