no data out-
422
put.
Ethernet
Data is
sometimes
output, but
sometimes
not.
RS-232C/
422
The read/Verification string
is not output.
There is more than one
Data Output Item, but data
is received from only the
last Data Output Unit in the
list.
A Timeout Error Occurred
Problem
A handshaking timeout
error occurred.
Vision System FH/FZ5 Series User's Manual
for Communications Settings (Z342)
Cause
The output IP address is incorrect.
There is a problem with the wiring or a cable
has been disconnected.
A connector has been disconnected.
You have not added any Data Output pro-
cessing items in the measurement flow.
The [Output] option is not selected in the
Adjustment Window.
The measurement commands are not being
received.
A cable has been disconnected.
The [Output] option is not selected in the
Adjustment Window.
The measurement commands are not being
received.
Character output have not been set.
The data output by the first Data Output Unit
is being overwritten by the data output by a
Data Output Unit executed afterwards.
Cause
The DSA signal is being turned ON and OFF
too slowly. The following patterns are possi-
ble.
• The DSA signal does not turn ON after a
measurement is completed.
• The DSA signal does not turn OFF after
the GATE signal turns ON.
• The DSA signal does not turn ON after the
GATE signal turns OFF.
The DSA signal is not being output or the
Sensor Controller is slow in recognizing that
the DSA signal has turned ON.
Action
Set the output IP address correctly.
Check the wiring.
Check the cable connections.
Check the connector connections.
You have not added any Data Output pro-
cessing items in the measurement flow.
Select the [Output] option in the Adjustment
Window.
If the BUSY signal stays OFF after sending a
measurement command, the measurement
command may not have been received.
Send measurement commands only when
the BUSY and FLG signals are both OFF.
Check the cable connections.
Select the [Output] option in the Adjustment
Window.
If the BUSY signal stays OFF after sending a
measurement command, the measurement
command may not have been received.
Send measurement commands only when
the BUSY and FLG signals are both OFF.
Set character output in the output parame-
ters for the character output processing items
(Character Inspection, Barcode, 2DCode,
etc.).
(Output for read/target strings is set up in the
above processing items, not in the Data Out-
put processing items.)
Use handshaking to control the data output
or use an offset to prevent this from happen-
ing.
Action
Turn the DSA signal ON or OFF within the
time interval set for the timeout time.
Check the timing of the DSA signal output in
the PLC program.
The signal may not be received correctly due
to noise.
