Functional characteristics
Configurable functions Number 1 of the 6 configurable functions (using the Advantys configuration software)
Frequency meter
This function measures the frequency received on the IN A input.
This frequency is always expressed in Hz (number of pulses per second), with a precision of
1 hertz.
Also measures the speed in Units per second. The number of points to be received on the IN A
input, corresponding to one unit, must be defined from one up to 255.
The maximal frequency on the IN A input is 40 kHz in both cases (without filtering).
Response time: < 0,2 s (frequency 2/40 kHz), < 1 s (frequency 0,2 kHz).
Count events
This function provides the value of the number of pulses received on the IN A input during a
selectable time unit. The time unit is configurable : 0.1s, 1s, 10 s or 1 minute.
The IN B input can be used to reset the internal time basis which provides the time unit.
The maximal number of pulses counted during a time unit is up to 65535.
The minimal pulses duration on the IN A input is 10 µs (without filtering).
Response time: < 0,5 ms
Measure time periods Measures the elapsed time during an event or between two evens (on IN A input) according to
the selectable time base of 10 µs, 100 µs or 1 ms. The max. event duration is 0.655, 6.55, or
65.5 seconds, respectively. The max. frequency on the IN A input is 200 Hz.
Response time: < 0.5 ms.
Down counting
The IN B input starts or restarts the counter by resetting the setpoint value defined by the high
threshold value. When the counter is running , any pulse received on the IN A input decreases
the counter.
The counter stops when it reaches 0.
The setpoint maximal value is 65535.
The maximal frequency on the IN A input is 40 kHz (without filtering).
Response time : < 0,5 ms
Loop (modulo) counting
The IN B input starts or restarts the counter by resetting the setpoint value to 0. The IN B input
also triggers the capture of the previous counting value before the counter is reset to 0.
When the counter is running , any pulse received on the IN A input increases the counter.
The counter turns back to zero automatically when the pulse number received equals the
modulo defined by the high threshold value.
The modulo maximal value is 65535.
The maximal frequency on the IN A input is 40 kHz (without filtering).
Response time : < 0,5 ms
Up/down counting
The RST input starts or restarts the counter by resetting the preset value.
When the counter is running, the counting increases or decreseases according to the pulses
received on the IN A and IN B inputs (default settings : IN A increases the counter and IN B
decreases the counter).
By configuration:
v the IN B input can define the counting direction of the pulses received on IN A.
v the IN A and IN B inputs can receivet the signals of an incremental encoder.
The counter value is limited to 0 as low limit and to 65535 as high limit.
Response time : < 0,5 ms
OUT 1 and OUT 2 output functions
According to requirements, each of the counting module’s two outputs can be configured for one
of the following operating modes:
v No direct action: the counter status and status words are processed by the island master
v The output is activated when the counter value is less than the low threshold
v The output is activated when the counter value is between the low threshold and the high
threshold
v The output is activated when the counter value is greater than the high threshold
v A pulse is generated on the output when the low threshold is exceeded (when counting
down)
v A pulse is generated on the output when the low threshold is exceeded (when counting up)
v A pulse is generated on the output when the high threshold is exceeded (when counting
down)
v A pulse is generated on the output when the high threshold is exceeded (when counting up)
v The output is activated as long as the counter is RUN (only available on downcouting
function)
v The output is activated when the counter is STOP
v The output is activated when the capture value is less than the low threshold (only available
on modulo function)
v The output is activated (according to the modulo) when the counter value is between the low
threshold and the high threshold
