VIPA SLIO - 4.4 Counter - Functions

n With activated HW gate activate a high level at gate the HW gate.
The counter may only start when HW gate and SW gate are set.
n With gate function "abort" counting begins again at the load value.
With "interrupt" counting is continued with the count.
You may set an upper and a lower limit by setting a load value as
start and an end value.
The hysteresis serves the avoidance of many toggle processes of the
output and/or the interrupt, if the counter value is in the range of the
comparison value. You may set a range of 0 to 255. The settings 0
and 1 deactivate the hysteresis. The hysteresis influences zero run,
comparison, over- and underflow.
The pulse duration tells for what time the output is set when the para-
meterized comparison criterion is reached. The pulse duration can be
set in steps of 2.048ms between 0 and 522.24ms. If the pulse dura-
tion = 0, the output is set active until the comparison condition is not
longer fulfilled.
4.4 Counter - Functions
You may count forward and backwards and choose between the fol-
lowing counter functions:
n Count endless, e.g. distance measuring with incremental encoder
n Count once, e.g. count to a maximum limit
n Count periodic, e.g. count with repeated counter process
In the operating modes "Count once" and "Count periodic" you may
define a counter range as start and end value via the parameteriza-
tion. For every counter additional parameterizable functions are avail-
able like gate function, comparison, hysteresis and process interrupt.
Via the parameterization you have the opportunity to define a main
counting direction for every counter. If "none" is chosen, the complete
counting range is available:
Limits Valid value range
Lower count limit
-2 147 483 648 (-2
31
)
Upper count limit
+2 147 483 647 (2
31
-1)
Main counting direction forward
Upper restriction of the count range. The counter counts 0 res. load
value in positive direction until the parameterized end value -1 and
jumps then back to the load value with the next following encoder
pulse.
Main counting direction backwards
Lower restriction of the count range. The counter counts from the par-
ameterized start- res. load value in negative direction to the parame-
terized end value +1 and jumps then back to the start value with the
next following encoder pulse.
END_I,LOAD_I End
value, Load value
HYST_I Hysteresis
PULSE_I Pulse (dura-
tion)
