High Speed Counter Encoder Module User Manual
In the Latch (default) position (left), this jumper selects the INDEX signal
to load the counter’s value into the output holding register. Set WY21.07
[Channel 1] and WY27.07 [Channel 2] to enable the Latch function.
With this jumper in the Reset-and-Go position (right), the INDEX signal
loads the counter’s value into the output holding register, and then clears
the counter to zero. Clear WY21.07 [Channel 1] and WY27.07 [Channel 2] to
enable the Reset and Go function.
With the Inhibit jumper in the Level (default) position (left), a high
INHIBIT signal pauses the counter; a low INHIBIT signal resumes the
counting.
With the Inhibit jumper in the Edge position (right), the leading edge of an
external INHIBIT pulse pauses the counter; later the leading edge of a
second external INHIBIT pulse resumes the counting.
NOTE:
Select one of the four (Compare, Rollover, Compare Toggle, or Latch)
jumper positions for Counter 1 [4].
The Compare jumper selects a one-clock-wide pulse that is active when the
count equals the preset 2 value [Channel 1] or preset 6 value [Channel 2].
This pulse appears on Output 1 [Channel 1] or on Output 5 [Channel 2].
Compare is the default jumper setting.
The Rollover jumper selects a signal that is active when the carry or borrow
signal is active from the counter. This signal appears on Output 1
[Channel 1] or on Output 5 [Channel 2].
The Compare Toggle jumper selects a signal that changes state when the
count equals the preset value. This signal appears on Output 1 [Channel 1]
or on Output 5 [Channel 2].
The Latch jumper selects a signal that is active when the count equals the
preset value; the signal remains active until cleared by the PLC, preset 2, or
preset 6. This signal appears on Output 1 [Channel 1] or on Output 5
[Channel 2].
