External Triggering, In0 - MICRO-EPSILON optoCONTROL 1202 Instruction Manual

6.5
When a HIGH-pulse at digital input INO is applied the external triggering at the hardware is activated.
i
Depending on the adjusted analog output mode the analog outputs and digital outputs are updated only, if
the trigger requirement is performed.
The receiver electronics resets the MAX/MIN value on INO with the new LOW/HIGH edge. During the HIGH-
pulse at IN0 (window) the MAX-MIN search to the drag indicator principle is active. The respectively actual
MAX/MIN value is inside this window output at pin 8/red. If the HIGH-pulse is reset on IN0, the during the
window detected MAX/MIN value persists on the analog output. First the next LOW/HIGH edge of the thereon
following window resets the analog value.
Fig. 13 Function of external triggering
The example in Fig. 13 requires a TRIG-MODE „EXT. INO HIGH" (Trigger Mode) and a ANA-OUT „MAXIMA"
(Analog Output Mode).
The trigger mode EXT IN0 L/H provides the actual measuring value with the rising edge at analog output.

External Triggering, IN0

The trigger mode is only possible in the both trigger modes „EXT. IN0 L/H" and „EXT. IN0 HIGH", see
the software description.
