Note:
The rapid digital inputs have to be assigned to the parameters
S-0-0401 and S-0-0402 (default setting of
P-0-0300, Digital
I/Os, assignment list
etc.)!
See "Digital Inputs/Outputs" in the same chapter
A switching edge at the probe input can trigger the detection of a
measured value. Switching edges, however, only cause a measured
value to be detected when the following requirements have been fulfilled:
•
The presetting for measured value detection with positive and/or
negative switching edge at the respective probe input was activated in
S-0-0169, Probe control parameter
.
•
The measured value detection was started via
S-0-0170, Probing
cycle procedure command
.
•
The respective probe input for measured value detection was enabled
(
S-0-0405, Probe 1 enable
or
S-0-0405, Probe 2 enable
).

it is possible to set,
separately for probe 1 and 2, in which mode the measurement is to take
place. The measured value detection must have been activated.
The following enable modes are possible:
•
Single measurement
After the respective probe has been enabled (S-0-0405 or S-0-0406) a
value is only detected at the first measured value trigger. Before every
other measurement a repeated probe enable is required!
•
Continuous measurement
After the respective probe has been enabled (S-0-0405 or S-0-0406) a
new measured value is detected at each measured value trigger.
