Gate Source
Select
Gate Input 0–3
from the Value menu to associate a
gate-input channel with a count-input channel. If the count-input
channel uses one of the external gate inputs, counting is enabled
when the gate-input signal is high and is disabled when the signal
is low, as shown in Figure 6. The gate-input signal is high when the
channel is ON. The external device determines the high and low
intervals of the gate-input signal. If you do not associate a
gate-input channel with the count-input channel, select
Always
Disabled
or
Always Enabled
. Select
Always Enabled
if you want
the count-input channel to count at all times, even if there is
nothing wired to the gate input. Always Enabled is the default
value.

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.
