For this, connect the
Signal for process access
to a binary input of the "DIO" module and
set the starting time of the measurements to
Continuous
. A measurement starts
immediately as soon as the signal at the binary input is active. The only exception is if a
calibration or cleaning is due on the basis of the set time intervals: in this case, these
activities are performed first of all and then the measurement follows immediately
afterwards. If necessary, connect the signal
Measurement active
to a binary output to
identify when the measurement actually begins. If you do not want any more
measurements after the end of the first measurement, you have to deactivate the
Signal
for process access
while the measurement is still running.
The following information is processed at the binary inputs or output at the binary
outputs:
• Binary inputs:
Signal for process access
: The analyzer can only perform activities that require sample
(measurement, calibration, cleaning) when the signal is active. The time and the
sequence of activities correspond to the settings in the setup. All activities that require
sample are delayed as long as the signal is inactive.
• Binary outputs:
• Signal
Measurement active
: Indicates that a measurement is currently running. The
signal is not active in the event of a calibration or cleaning.
• Signal
Sample required
: The signal is active for a configurable time before every
activity that requires sample. This makes it possible to activate an external pump or a
dilution module, for example.
