Read Reset Mode
You can configure each count-input channel to reset each time the
FieldPoint network module reads it by selecting
Reset on Read
from the Value menu. A read-initiated reset also resets any outputs
associated with the target channel. The default is Don’t Reset
On Read.
Note
Read Reset mode is not intended to be used with
FieldPoint Ethernet network modules.
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.
