NOTE
If you do not require pulse
-
counting on
a line
then configure
it
as
a Form
-
A alarm input
so that
all other pulse
-
counting inputs
ha
ve
access to
as much
storage space as
possible.
The data collection system (
DC
-
2009
®
or
MV90
®
) must know how many pulse
-
counting
channels are activated. The minimum is 1
and t
he maximum is
4.
When the data collection system receives the pulse records from the CNI2 it expects them to be
in a specific order starting with the 1
st
inp
ut and ending with the last. The CNI2 does not have
restrictions regarding the order in which you program the pulse
-
counting lines. You could
program Line #1 and Line #2 as alarms and #9 and #10 as pulse
-
counters. To stay compliant
with DC
-
2009 here
is how the records are sent:
The very 1st line that is programmed for pulse counting is considered “Input
-
1”.
The next line that is programmed for pulse counting is considered “Input
-
2”.
The next line that is programmed for pulse counting is considered “I
nput
-
3”.
The next line that is programmed for pulse counting is considered “Input
-
4”.
Remember that a Form
-
C pair is treated as only one input.
Here’s an example:
Lines #1, 2, 9 and 10 are configured as alarm inputs and Lines #11 and #12 for pulse
-
count
ing.
Line #11 is presented as “Input
-
1” to DC
-
2009 because it’s the 1st line programmed for pulse
-
counting. Line #12 is presented as “Input
-
2” because it’s the 2nd line programmed for pulse
-
counting.
Here’s another example involving a mixture of Form
-
C a
nd Form
-
A settings:
Lines #1 and #2 are programmed for pulse
-
counting, Form
-
A operation. Lines #11 & #12 are
configured for Form
-
C pulse counting. Line #1 is presented as “Input
-
1” to DC
-
2009 because
it’s the 1st line programmed for pulse
-
counting. Lin
e #2 is presented as “Input
-
2” because it’s
the 2nd line programmed for pulse
-
counting. Lines #11/#12 are presented as “Input
-
3” because
they are the 3rd set of lines programmed for pulse
-
counting.
