Setting RS-232C and Discrete I/O Communication Conditions
The default settings are indicated with an asterisk (*).
Setting item Settings Details
Trigger Mode Select how to use the trigger signal for discrete I/O.
One Shot* Reading is performed once at the rise of trigger signal (OFF →
ON). If reading is successful, it will be exited and the reading
results will be output.
Since the trigger signal is synchronized with the camera shutter
input, shooting of moving workpieces can be performed at
accurate positions.
Level Reading is repeated while the trigger signal is ON, until reading
is successful. If reading is not successful, “NG” will be output
when the trigger signal is turned OFF.
Continuous Reading is performed continuously while the trigger signal is
ON.
Trigger Error Select whether to output a discrete I/O error when a trigger is received during BUSY.
ON* A discrete I/O error will be output when a trigger is received
during BUSY.
OFF No discrete I/O error will be output even if a trigger is received
during BUSY.
Polarity Set the trigger signal active polarity.
Low Active* The trigger signal is active when it is low.
High Active The trigger signal is active when it is high.
OK/NG Output Select the OK/NG signal output method.
OK Pulse* A pulse signal will be output when reading is successful.
NG Pulse A pulse signal will be output when reading fails.
Level Output Outputs OK/NG at low/high levels.
Pulse Width 10 to 100 (10*) Specify the width (msec) of the pulse signal if a pulse signal is
to be output.
