NC400-6 Counter
NOVUS AUTOMATION
2/7
BATCH COUNTER
Counts the number of times that Set point 2 for the main counter was
reached, with manual or automatic reset. When its Set point is
exceeded (greater than or equals to) results in configurable actions
(enable output or increment totalizer counter). It is always a
progressive counter. The following configuration parameters are
directly related to the batch counter operation.
SP bAt
Batch counter Set point.
OFF.bAt
Initial value (O
ffset
) for the batch counter.
rES.bAt
Reset
options for the batch counter (input,
key, Set point, output, etc.).
TOTALIZER COUNTER
Totalizes the main counter or the number of times that the batch
counter Set point was reached, with manual or automatic reset.
When its Set point is reached (greater than or equals to) it can
activate an output. The following configuration parameters are
directly related to the totalizer operation.
Opt.tot
Totalizer counting option (input pulse or
batch)
SP tot
Totalizer Set point.
OFF.t
Initial value (
Offset
) for the totalizer.
rES.tot
Reset
options for the totalizer (input, key,
Set point, output, etc.).
OUT1
This output is always associated to the main counter, and it is
activated when Set point 1 is reached
, and disabled with time,
reset, Set point 1 or when OUT2 is enabled. The following
configuration parameters are directly related to the OUT1 operation.
Out1.t
Time to deactivate OUT1 (
0.00
to
9999.99
s).
Out1.E
Turn-off options of OUT1 (time, OUT2,
reset
, Set point 2).
Out1.OP
Freeze counting while OUT1 is activated
(yes, no).
Out1.c
OUT1 normal state open or closed.
OUT2
This output can be activated by Set point 2 of the main counter, by
the batch counter Set point or by the totalizer Set point. It can be
deactivated by time, reset, activation of OUT1 or Set point that
activated it. The following configuration parameters are directly
related to the OUT2 operation.
Out2.SE
OUT2 activation options (Set point 2, batches
or totalizer).
Out2.t
Time to deactivate OUT2 (
0.00
to
9999.99
s).
Out2.E
Turn-off options of OUT2 (time, OUT1,
reset
).
Out2.OP
Freeze counting while OUT2 is activated
(yes, no).
Out2.c
OUT2 normal mode open or closed.

COUNTING MODES
The
Coun.tY
parameter selects the counting mode as slow or fast.
In the slow counting mode, a filter is applied to the counting signals,
limiting the maximum pulse frequency, which is necessary to count
the number of activations of electromechanical contacts. In the fast
counting mode, NC400-6 operates up to the maximum frequency
specified for the input signal. The frequency limits for each mode are
defined in
Item 5
.
The
Coun.UP
parameter defines the main counting direction (UP or
DOWN) and the function of each input.
Table 1
shows options for
this parameter.

Table 1
– Counting modes that can be selected with the
Coun.UP
parameter.
The main counting direction affects the main counter:
Main direction UP:
Main counter count upstream, starting from
the Offset value defined (usually zero).
Actions can be programmed to take place
in Set point 1 and 2 values.
Main direction DOWN: The main counter count downstream,
starting from the Set point 2 value (
SP2C
).
The action programmed for this Set point
will take place when the counter reaches
the programmed Offset value.
The totalizer direction is always up.
Operation descriptions in this manual consider that
the NC400-6 counter is operating in the UP direction.
To operate in DOWN direction, refer to the
explanation above.
You can select functions for COUNT1 and COUNT2/HOLD inputs:
ADD:
Progressive counting input.
SUB:
Regressive counting input.
HOLD:
Stops the counting input for COUNT1.
