BUSY Busy Signal This signal tells when new com-
mands and other external inputs
cannot be acknowledged during pro-
cessing of other external inputs.

Just because this signal is ON
does not necessarily mean that a
command is being executed. To
check whether a command is
being executed, access the Com-

ERR Error Signal The FQ2-S/CH series provides
notification with this signal when
it detects the following errors.
Refer to Section 8 Trouble-
shooting in Vision Sensor FQ2-
S/CH User's Manual (Cat. No.

• Communication timeout
• TRIG Input while measure-
ment
The ERR signal does not turn
OFF even after the error is elimi-
nated. The signal turns OFF only
when the error status is cleared
by a control command.
