Description
Allocate a process variable to the respective data logging channel.
Selection
• Off
• Level linearized
• Distance
• Terminal voltage
• Electronic temperature
• Absolute echo amplitude
• Relative echo amplitude
• Analog output adv. diagnostics 1
• Analog output adv. diagnostics 2
Factory setting
Off
Additional information
A total of 1000 measured values can be logged. This means:
• 1000 data points if 1 logging channel is used
• 500 data points if 2 logging channels are used
• 333 data points if 3 logging channels are used
• 250 data points if 4 logging channels are used
If the maximum number of data points is reached, the oldest data points in the data log
are cyclically overwritten in such a way that the last 1000, 500, 333 or 250 measured
values are always in the log (ring memory principle).
The logged data are deleted if a new option is selected in this parameter.
Logging interval
Navigation
Diagnostics → Data logging → Logging interval
Description
Define logging interval t
log
.
User entry
1.0 to 3
600.0 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
= 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
