Ch-B Totalizer Add/Subtract by
Digital Input (
ud BI
)
Total of channel B will add or subtract as determined
by the state of a digital input. Channel B total will add
at each falling edge if an assigned digital input is high,
and subtract at each rising edge if an assigned digital
input is low.
Ch-A & Ch-B Totalizer
Add/Subtract by Digital Input
(
ud aB
)
Totals of channel A and B will add or subtract as
determined by the state of a digital input assigned to
each channel. This mode combines the features of
ud
AI
and
ud BI
.
This setting requires the use of a
expansion module (see
). The F4 digital input will only support one channel.
Quadrature Input Type 1 (
quad 1
)
Quadrature modes are used to accept inputs that are
±90 degrees out of phase, from quadrature output
devices. Total of channel A will add or subtract as
determined by the state of input channel B. Channel A
total will add at each rising edge if channel B is high,
and subtract at each rising edge if channel B is low.
Quadrature Input Type 2 (
quad 2
)
Quadrature modes are used to accept inputs that are
±90 degrees out of phase, from quadrature output
devices. Total of channel A will add or subtract as
determined by the state of input channel B. Channel A
total will add at each rising edge if channel B is high,
and at each falling edge if channel B is low. Channel
A total will subtract at each rising edge if channel B is
low, and at each falling edge if channel B is high.
Quadrature Input Type 4 (
quad 4
)
Quadrature modes are used to accept inputs that are
±90 degrees out of phase, from quadrature output
devices. Totals of channel A and B will add at each
rising and falling edge of that channel.
