Conveyor work area signals
DescriptionSignal
Digital output signal. This signal is used if an overflow shall be
avoided by letting the conveyor movement be controlled by
the work area. The signal goes high when the conveyor shall
start moving and goes low when the conveyor shall stop to
avoid an overflow.
Conveyor start/stop
Digital output signal. This signal is high when the queue for
this work area is empty. The signal goes high when the last
item is retrieved from the queue.
Queue idle
Digital output signal. This signal is high when there is one or
more items between the enter and exit limits for the work area.
Position available
Digital input signal that tells that it is time to generate a new
vision image or generate new predefined positions. This signal
is ignored if a distance triggered conveyor is used.
Position generator
If vision is used this digital output signal must be connected
to the trigger input on the I/O port on the camera. If predefined
positions are used this output signal must be connected directly
to the start input on the conveyor encoder board. This is best
done using the doManSyncX signal. If predefined positions are
distributed only to this work area (For instance, Runtime with
a single robot),the encoder signal cXSoftSyncSig can be used
instead of doManSyncX, that is, without the need of connecting
a signal to the start input of the encoder board.
Trig
This is the input signal name for the strobe signal and is the
start signal for the encoder board for the conveyor. The signal
name is set to cXNewObjStrobe. If vision is used the signal
must be generated from the strobe output on the I/O port of
the camera. When predefined positions are used, the strobe
may be generated directly from the doManSyncX signal, which
is directly connected to the start signal on the encoder board.
