ifm function elements for the device CR0403
Description
TRUE: execute this function element
FALSE: unit is not executed
> Function block inputs are not active
> Function block outputs are not specified
number of the input channel pair (0/2):
0 = channel pair 0 = inputs I00 + I01
2 = channel pair 1 = inputs I02 + I03
counter start value
FALSE  TRUE (edge):
PRESET_VALUE is loaded to COUNTER
TRUE: Counter ignores the input pulses
FALSE: Counter counts the input pulses
evaluation of the encoder resolution:
01 = counts for every fourth edge (= resolution of the encoder)
02 = counts for every second edge
04 = counts for every rising and falling edge
All other values count as "01".
Description
if RESOLUTION = 1:
VALUE = –536 870 912...536 870 911
(= ¼ area of DINT)
if RESOLUTION = 2:
VALUE = –1 073 741 824...1 073 741 823
(= ½ area of DINT)
if RESOLUTION = 4:
VALUE = –2 147 483 648...2 147 483 647
(= area of DINT)
TRUE: counter counts upwards in the last cycle
FALSE: counter counts not upwards in the last cycle
TRUE: counter counts downwards in the last cycle
FALSE: counter counts not downwards in the last cycle
