Double Coil Designation
If this is NOT ON then the second Y3 coil does NOT activate. Therefore the status of the Y3
coil updates to reflect this new situation, i.e. it turns OFF. The final outputs are then Y3 = OFF
and Y4 = ON.

program shown opposite identifies a double
coil situation; there are two Y3 outputs. The
following sequence of events will occur when
inputs X1 = ON and X2 = OFF;
1.The first Y3 tuns ON because X1 is ON. The
contacts associated with Y3 also energize
when the coil of output Y3 energizes. Hence,
output Y4 turns ON.

program looks at the status of input X2.
handle such high speed input requests.
Input durations:
The ON or OFF duration of the PLC inputs
must be longer than the operation cycle
time of the PLC.
Taking a 10 msec (standard input filter)
response delay into account, the ON/OFF
duration must be longer than 20 msec if
the operation cycle (scan time) is 10 msec.
Therefore, in this example, input pulses of
more than 25Hz (1sec/(20msec ON +
20msec OFF)) cannot be sensed.
