17 Programmable Logic Controller (PLC)
Functional Blocks
This section provides descriptions of the PLC functional blocks.
GPIO Blocks
The GPIO blocks allow the video interface to communicate with exterior objects in your vision system
through the 12-pin circular connector of the video interface.
Camera/Pixel Bus Block
The Camera/Pixel Bus block allows the communication between the camera and the video interface. The
block receives a video signal and provides the video with discrete frame valid (FVAL), line valid (LVAL),
and similar signals. Some cameras allow you to send control signals back to the camera through the
Pb0CC[3:0] or Pb1CC[3:0] for the second video source.
