Set value
Data registers are always used for the Command Area.
Set the first word address in the Command Area.
Data registers are always used for the Response Area.
Set the first word address in the Response Area.
Data registers are always used for the Data Output Area.
Set the first word address in the Data Output Area.
Sets whether to establish an interlock with the PLC when data is output.
None: Data is output regardless of the status of signals from the PLC. GATE is
always OFF.
Handshaking: Data is output after confirming DSA from the PLC.
Selected:
IMPORTANT
Always set the output control to [Handshaking] for asynchronous output. If
you set the output control to [None], operation will be fixed at the following
values: Output time: 100 ms, Output period: 200 ms.
If you need a shorter output time and output period when the output control
is set to [None], do not select asynchronous output.
Not selected: Measurement processing and data output processing are syn-
Note
This is the same as the PLC Link operation of the FZ4 Vision Sensor.
Reference:
Set the time after which a timeout error will occur due to failing in establishing
PLC link communications.
The error is caused by making incorrect communication settings or disconnec-
tion of communication cables, and similar causes.
After a timeout error occurs, communications with the destination device will
be attempted at the interval time that is set as the retry interval.
Reference:
*1: If handshaking is enabled, a timeout error will also occur if any of the
following operations are not performed during the [Retry interval].
• If the DSA signal is not turned ON after a certain time elapses from
when measurements are finished
• If the DSA signal is not turned OFF after a certain time elapses from
when the GATE signal turns ON
• If the DSA signal is not turned ON after a certain time elapses from
when the GATE signal turns OFF.
Description
Measurement processing and data output processing are per-
formed in parallel. The data output processing does not affect
the processing time of the measurement flow.
chronized so that all data output processing is finished when
measurements are finished. This increases the overall process-
ing time of the measurement flow.
