Communication with the Host
Output signal
Output signal
Function
RUN
Turns ON during
RUN
mode.
BUSY
Shows that the V530-R160 is reading an image, changing settings, etc. Do not input the
next command while the BUSY signal is ON. Otherwise, the commands input during com-
mand execution or processing may not be properly executed.
OK/NG
Outputs the judgement under the set reading conditions. (Can be set to turn ON for either
OK or NG judgement.)
GATE
Used to control the timing with which the reading judgement is read at the host device.
The duration for which the GATE terminal is turned ON can be set as required for the host
device to correctly read the reading judgement.
Make the output cycle longer than the gate ON delay plus the gate ON time, but shorter
than the duration of the reading (TRIG A input). If the cycle is longer than the duration of
the reading, the input timing falls behind as readings are repeated. Gate ON delay, Gate
ON time and Output period are set under the set communications conditions.
Refer to page 192.
Input signal
Signal
Function
TRIG A
The reading trigger is input from a device such as a photoelectric switch. One reading is
performed on the rising edge (OFF to ON) of the TRIG A signal.
Turn ON for at least 0.5 ms.
The duration of TRIG A signal input depends on reading time. While reading is being per-
formed, the BUSY signal turns ON and input signals are not accepted. Refer to System
Examination for the standard reading time.
Refer to page 200.
