Permanent data logging
The variables w, x, y, and e are logged ac-
cording to the adjusted scan rate and saved
in the FIFO memory which always stores the
last 100 measured data points of each vari-
able.
Triggered data logging
On selecting
Trigger
in the
Selection
param-
eter, the data logger records the measured
data permanently in the background. A trig-
gering event leads to the last 100 measured
data points being stored together with the
pretrigger time and leads to the data log-
ging of the triggering condition.
The following parameters can be changed
for this function:

Triggered by the travel condition
(setpoint) and/or solenoid valve condi-
tion (forced venting)

tion (setpoint) the data logger should be

start when the travel condition (setpoint)
exceeds or falls below the start value.
