Description
UP/DOWN
COUNTER
input A
input B
output
0
INPUT A provides a rising edge trigger to increment the output count by
one.
INPUT B provides a rising edge trigger to decrement the output count by
one.
INPUT C holds the output at zero.
The output starts at zero. The output is limited at ±300.00.
(A*B)/C ROUND The OUTPUT is set to (INPUT A * INPUT B) / (INPUT C). This is the same
as (A*B)/C (enumerated value 3) except that the result is rounded.
WINDOW
NO HYST
This is the same as WINDOW (enumerated value 19) except that there is no
hysteresis when inside the `window’. Thus, from the diagram given in
WINDOW, if INPUT B = 5 and INPUT C = 4 then the range is 3 to 7.
WINDOW
B<=A<=C
input C
input B
output
0
input A
INPUT B and INPUT C are the upper and lower levels of the band.
If B<= C and A is in the band then the OUTPUT is TRUE, else OUTPUT is
FALSE
If C<B and A is in the band then the OUTPUT is FALSE, else OUTPUT is
TRUE (i.e. output is inverted)
Note:
OUTPUT is set to FALSE if the TYPE is changed or is in
initialisation.
A<=B
OUTPUT
INPUT A
INPUT B
The OUTPUT is TRUE if
INPUT A is less than or equal to
INPUT B, otherwise the
OUTPUT is FALSE.
((A*B)/100)+C
The OUPUT is set to ((INPUT A * INPUT B)/100)+C.
MIN (A,B,C)
The OUTPUT is set to the smallest of INPUT A, INPUT B and INPUT C.
MAX (A,B,C)
The OUTPUT is set to the largest of INPUT A, INPUT B and INPUT C.
