Measurement procedure
With a signal edge at the relevant
input, the current actual values of
an encoder connected to a control
unit are measured with positioning
accuracy to determine lengths and
distances.
With a signal edge at the relevant input, the
current actual values of one or more
encoders are measured using time stamp
functionality with positioning accuracy in order
to provide information for determining lengths
and distances (possible with any encoders
included in the project).
Configuration of the TO
measuringInput in SIMOTION
SCOUT
The assignment of inputs is always
permanent depending on the
hardware of the control unit and is
performed during the configuration
of the measuring input TO using
the measuring input number.
The assignment of inputs is not fixed
depending on the hardware and is performed
during the configuration of the TO
measuringInput by means of symbolic
assignment or the hardware address.

D410, D410-2, D4x5, D4x5-2 (terminal X122,
X132), CX32, CX32-2, CU310, CU310-2,
CU320, CU320-2:
The minimum interval between two
measurements is 3 position control cycle
clocks (max. 2 edges per measurement).
D4x5-2 (terminal X142), TM17 High Feature:
The minimum interval between two
measurements is 1 position control cycle
clock (max. 2 edges per measurement).
TM15:
No cyclic measurement available
Use of multiple measuring input TOs

1)
Measurement jobs must be issued individually for each measurement. Several interpolation cycle clocks lie between
two measurements.
2)
The measuring is activated just once and runs cyclically until deactivated
