MACHINE INTERFACE
153
The machine operator’s panel interface unit (A16B–2201–0110) is
connected to the control unit through the I/O Link and is used for
interfacing with the machine operator’s panel.
It features interfaces with matrix key switches, LEDs and manual pulse
generators.

D Matrix key switch inputs (matrix DI)
Ninety–six DI points are provided by a matrix of twelve common
signals times eight data signals. Note that I/O Link allocation may
limit the number of usable key switch inputs.
D Matrix LED data outputs (matrix DO)
Sixty–four DO points are provided by a matrix of eight common
signals times eight data signals.
D General–purpose switch inputs (general–purpose DI)
Each general–purpose DI point has an individual interface.
D General–purpose LED data outputs (general–purpose DO)
Each general–purpose DO point has an individual interface.
