(a) Scan input
An example is shown of a scan input circuit manufactured by the machine manufacturer.
(Note)
To scan input, connect a sneak path prevention diode as shown in the following drawing. The
unit may not be able to read the correct input signals without a sneak path prevention diode
installed.
The common signals are changed over with scan input as shown in the following drawing. Key input data
can be received when the common signal is LOW. The common signal changeover cycle is 11.68ms, but
the input signal will not be recognized unless it is held for the ladder processing cycle time or longer. The
scan input is a 5V system.
