3.7 "Measuring input" technology object
Use the "Measuring input" technology object for precise and
fast recording of actual position values.
In S7T Config, you can assign a measuring sensor to an axis or to a single external
encoder. Connect the measuring sensor to a digital input of the drive component,
or to a TM15/TM17 High Feature module.
The measurement of actual position values is initiated by means of the Motion
Control command "MC_MeasuringInput" in the user program of the CPU. The
operating range of the measuring sensor can here be limited by means of a start
and end value.
The actual position value is recorded and saved at the positive or negative edge of
the measuring sensor signal. The measuring function can be triggered at both
edges, provided the component used supports this mode.
