Data type Description
INT Preset value input in [increments].
INT Max. preset value positive direction in [increments]
(negative values also permissible).
INT Min. preset value positive direction in [increments]
(negative values also permissible).
INT Max. preset value negative direction in [increments]
(negative values also permissible).
INT Min. preset value negative direction in [increments]
(negative values also permissible).
INT Rising edge of the ramp
in [increments/PLC cycle] or [increments/TIMEBASE].
0 = without ramp
INT Falling edge of the ramp in
in [increments/PLC cycle] or [increments/TIMEBASE].
0 = without ramp
TIME Reference for rising and falling edge of the ramp:
t#0s = rising / falling edge in [increments/PLC cycle]
else = rising / falling edge in [increments/TIMEBASE]
ARRAY [0..10] Pairs of values describing the curve
OF POINT
The first pairs of values indicated in N_POINT are used.
N = 2...11
Example: 9 pairs of values declared as variable VALUES:
VALUES: ARRAY[0..10] OF POINT :=
(X:=0,Y:=0),(X:=200,Y:=0), (X:=300,Y:=50), (X:=400,Y:=100),
(X:=700,Y:=500), (X:=1000,Y:=900), (X:=1100,Y:=950),
(X:=1200,Y:=1000), (X:=1400,Y:=1050);
There may be blanks between the values.
BYTE Number of points (pairs of values in VARIABLE_GAIN) by
which the curve characteristic is defined. N = 2...11
