Noise Rejection
Each count-input channel has a software-enabled lowpass filter
that you can set to reject frequencies above 200 Hz or 50 kHz.
Select
200 Hz
or
50 kHz
from the Value menu to configure noise
rejection. The default is 50 kHz.
Control
You can set the Control command to increment or reset by selecting
Increment
or
Reset
from the Action menu. The increment-control
command increases the count-input channel in value by one. The
reset-control command resets the count-input channel. The control
commands ignore the gate-source setting and gate-input state.
Configuring Gate-Input Channels
Channels 8–11 are gate-input channels. The only difference
between the input circuits of the gate-input channels and those of
the count-input channels is that the gate-input channels do not have
a programmable lowpass filter. The states of the gate inputs can
always be read as simple digital inputs on Channels 8–11.
You do not need to configure anything in software for the
gate-input channels.
Configuring Output Channels
Channels 12–15 are digital output channels. In the Channel
Configuration dialog box of FieldPoint software, you can select
attributes for each output channel from the Attributes menu. The
following sections describe the different attributes you can select
for output channels.
Output Source
You can configure each output channel to operate either as an
associated output for one of the eight count-input channels or as
a generic digital output. Select
Counter Channel 0–7
from the
Value menu if you want the digital output channel to operate as an
output for a corresponding count-input channel. Select
Discrete
Data
from the Value menu if you want to use this channel as a
generic digital output. When you write data to an output channel,
you affect the output state only if you configure the Output Source
as Discrete Data.
