for Communications Settings (Z342)
Function
This signal tells when com-
mands and other external
inputs cannot be acknowl-
edged.
Make sure this signal is OFF
before you request a com-
mand.
*1: During continuous
measurement, the BUSY
signal remains ON. The FH
accepts the Command
Request signal only after
receiving the End
Continuous Measurement
command.
Note:
• The execution of commands
or other processing
received through any other
protocol cannot be
detected. (Example: This
signal remains OFF during
measurements for a parallel
communications Trigger
signal.)
If you use more than one
protocol and need to detect
command execution, use
the parallel communications
BUSY signal.
• ON of this signal does not
indicate that the command
is being executed. To check
whether the command is
being executed, check the
status of the Command
Completion signal.
The Vision Sensor uses this
signal to tell the user (PLC)
that command execution has
been completed.
ON/OFF timing

this signal when it receives a

(The signal turns ON after the
Command Request signal

cution of a received command.
