 Diagnostics → Data logging → Logging interval
Define logging interval t
log
1.0 to 3 600.0 s
30.0 s
This parameter defines the interval between the individual data points in the data log, and
thus the maximum loggable process time T
• If 1 logging channel is used: T
• If 2 logging channels are used: T
• If 3 logging channels are used: T
• If 4 logging channels are used: T
Once this time elapses, the oldest data points in the data log are cyclically overwritten such
that a time of T always remains in the memory (ring memory principle).
log
The logged data are deleted if this parameter is changed.
Example
When using 1 logging channel
• T = 1000 ⋅ 1 s = 1 000 s ≈ 16.5 min
log
• T = 1000 ⋅ 10 s = 1 000 s ≈ 2.75 h
log
• T = 1000 ⋅ 80 s = 80 000 s ≈ 22 h
log
• T = 1000 ⋅ 3 600 s = 3 600 000 s ≈ 41 d
