Description
The function INC_ENCODER is an up/down counter up to a
limit frequency of approx. 10 kHz. Two frequency inputs form an
input pair which is evaluated via the function. A total of 4
incremental encoders can be connected.
The counter can be set to a preset value via PRESET_VALUE.
The value is accepted when PRESET is set to TRUE. PRESET
then has to be reset to FALSE so that the counter becomes
active. Output COUNTER shows the current count.
The outputs UP and DOWN show the current count direction of
the counter. The outputs are TRUE when the counter has
counted in the direction in question in the previous program
cycle. When the counter stops the directional output is reset in
the following program cycle.
