7.4.4 Remote Calibrations
Fig. 7-7: Digital Inputs - Initializing Calibrations
Example 1:
Signal A starts a ZeroAll calibration
Signal B is applied during the ongoing ZeroAll calibration. It ends more than 1 sec after the calibration is nished,
so the related SpanAll calibration is initialized.
Example 2:
Signal C initializes a SpanAll calibration.
Signal F is applied during the ongoing procedure and cancels it after the minimum 2 seconds duration.
In the following conguration input IN1 starts
a ZeroAll calibration, IN2 a SpanAll calibration
and IN3 is assigned "Cancel Calibration".
The related procedure is initialized by a rising
edge, subsequently followed by a signal with
a duration of at minimum 2 seconds.
Additional triggers applied to any inputs du-
ring an ongoing calibration are considered
only, if the subsequent signal is still applied
for at minimum 1 second, after the ongoing
procedure has nished.
Multiple triggers applied to several calibration
related inputs at the same time are evaluated
in relation to their order of application: The
rst signal applied is the rst one evaluated.
