Logging interval
Description Define logging interval t
log
.
User entry 1.0 to 3600.0 s
Factory setting 30.0 s
Additional information This parameter 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 x t
log
• If 2 logging channels are used: T
log
= 250 x t
log
• If 3 logging channels are used: T
log
= 166 x t
log
• If 4 logging channels are used: T
log
= 125 x 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 memory (ring memory
principle).
Note: The logged data are deleted if this parameter is changed.
Example
When using 1 logging channel
• T
log
= 500 x 1 s = 500 s

8.5 min
• T
log
= 500 x 10 s = 5000 s  1.5 h
• T
log
= 500 x 80 s = 40000 s

11 h
• T
log
= 500 x 3600 s = 1800000 s

20 d
