Type 3 oforations: UP/DOWN COUNTER with prescaler x1,
x10, x100, x1000 of the logical input (d) + reset logical input
(c) with threshold (UP) or preset (DOWN) analogue (a) and
digital output at end of count + analogue counter output (b)
UP COUNTER with prescaler x 1: increases the value of
the analogue output of the Math Function every time the
parameter connected with digital input "Input d" switches
from low logical value to high logical value (rising edge).
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on
the logical value HIGH when the value appearing on the
analogue output of the Math Function Block reaches the
value of the parameter connected with analogue input "Input
a". Until then, the digital output of the Math Function Block
will remain on LOW logical value.
UP COUNTER with prescaler x 10: : increases the value
of the analogue output of the Math Function every time the
parameter connected with digital input "Input d" switches
from low logical value to high logical value (rising edge) ten
times.
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on
the logical value HIGH when the value appearing on the
analogue output of the Math Function Block reaches the
value of the parameter connected with analogue input "Input
a". Until then, the digital output of the Math Function Block
will remain on LOW logical value.
UP COUNTER with prescaler x 100: iincreases the value
of the analogue output of the Math Function every time the
parameter connected with digital input "Input d" switches
from low logical value to high logical value (rising edge) one
hundred times.
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on
the logical value HIGH when the value appearing on the
analogue output of the Math Function Block reaches the
value of the parameter connected with analogue input "Input
80209C_MHW_850-1650-1850_01-2020_ENG_pag. 234
a". Until then, the digital output of the Math Function Block
will remain on LOW logical value.
UP COUNTER with prescaler x 1000: increases the value
of the analogue output of the Math Function every time the
parameter connected with digital input "Input d" switches
from low logical value to high logical value (rising edge) one
thousand times.
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on
the logical value HIGH when the value appearing on the
analogue output of the Math Function Block reaches the
value of the parameter connected with analogue input "Input
a". Until then, the digital output of the Math Function Block
will remain on LOW logical value.
DOWN COUNTER with prescaler x 1: decreases the value
of the analogue output of the Math Function, starting with
the value of the parameter connected with analogue "Input
a", every time the parameter connected with digital input
"Input d" switches from low logical value to high logical value
(rising edge)
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on the
logical value HIGH when the value appearing on the analogue
output of the Math Function Block is zero. Until then, the
digital output of the Math Function Block will remain on LOW
logical value.
DOWN COUNTER with prescaler x 10: decreases the value
of the analogue output of the Math Function, starting with
the value of the parameter connected with analogue "Input
a", every time the parameter connected with digital input
"Input d" switches from low logical value to high logical value
(rising edge) ten times
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on the
logical value HIGH when the value appearing on the analogue
output of the Math Function Block is zero. Until then, the
digital output of the Math Function Block will remain on LOW
logical value.
DOWN COUNTER with prescaler x 100: decreases the
value of the analogue output of the Math Function by one,
starting with the value of the parameter connected with
analogue "Input a", every time the parameter connected with
the digital input of the Math Function Block remains at LOW
logical value.
The value of the analogue output of the Math Function Block
will remain at zero for as long as the value of the parameter
connected with digital input "Input c" keeps RESET input
high.
The digital output of the Math Function Block will take on the
logical value HIGH when the value appearing on the analogue
output of the Math Function Block is zero. Until then, the
digital output of the Math Function Block will remain on LOW
