This register reflects the current input signal status.
When the interrupt enable flag is set to ON (DE='1') and the rising edge detection is
selected (UE='1'), the CD633 sets corresponding bit of the change detection status
register (US) and generates interrupt to the controller at the time of input signal change
from OFF to ON.

As same manner, when the falling edge detection is selected (LE='1'), the CD633
generates interrupt at the time of input signal change from ON to OFF.

Overview
The change detect DC input module CD633 is an 16 points 12-24 Vdc input module with
interrupt generation function. When the input signal status of the CD633 is changed, the
CD633 generates an interrupt for the controller (S2T/S2).

Precautions
(1) I/O interrupt function is available only in the main unit. Mount the CD633 on the
basic unit.
(2) If input wiring is long, take measures to prevent erroneous input caused by noise,
as follows.
a) Wiring length must be minimized. Do not make unnecessary loops.
b) Keep the input wires away, at least 200 mm, from power cables and high
b) Keep the input wires away, at least 200 mm, from power cables and high
frequency lines, or shield the input cables with a metal plate.
c) To improve noise immunity, use a shielded cable and/or twisted-pair cable.
d) Install a bleeder resistor to reduce input impedance.
d) Install a bleeder resistor to reduce input impedance.
(3) Because the input filter time constant of CD633 is set to small, CD633 may read the
wrong input due to chattering of mechanical-contact. Use solid-state device for the
CD633. Also, take measures to suppress noise.
CD633. Also, take measures to suppress noise.
(4) Check the leakage current and the voltage drop of the connected solid-state
devices. It must be within the CD633 specification.
(5) The change detection status of CD633 is cleared to '0', when the controller read the
change detection status and input data. Therefore make the application program to
read the change detection status and input data (3 words) at the same time by the
direct I/O instruction, in the I/O interrupt program.
read the change detection status and input data (3 words) at the same time by the
direct I/O instruction, in the I/O interrupt program.
(6) CD633 is executing the change detection operation even in the controller is HALT.
In order to clear the change detection status at the beginning of RUN mode, make
the application program to read the change detection status and input data (3
words) at the first scan.
