parameter (→  45).
Description Use this function to enter the logging interval T
log
for data logging.
User entry 0.1 to 3 600.0 s
Factory setting 1.0 s
Additional information Description
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
= 1000 × t
log
• If 2 logging channels are used: T
log
= 500 × t
log
• If 3 logging channels are used: T
log
= 333 × t
log
• If 4 logging channels are used: T
log
= 250 × 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).
The log contents are cleared if the length of the logging interval is changed.
Example
If 1 logging channel is used:
• T
log
= 1000 × 1 s = 1 000 s ≈15 min
• T
log
= 1000 × 10 s = 10 000 s ≈ 3 h
• T
log
= 1000 × 80 s = 80 000 s ≈ 1 d
• T
log
= 1000 × 3 600 s = 3 600 000 s ≈ 41 d
