Measuring on virtual axes
Measuring on axes attached to a

SIMOTION Utilities & Applications includes, for example, a tool with the following functions:
● Estimate of the time between initiating a measurement job to the time at which the

Local measuring input
D410, D410-2, D4x5, D4x5‑2
(terminal X122/X132), CX32,
CX32‑2, CU310, CU310-2, CU320,
CU320‑2
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.
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.

Global measuring input
TM15, TM17 High Feature, D410, D410-2,
D4x5, D4x5‑2 (terminal X122, X132, X142),
CX32, CX32‑2, CU310, CU310-2, CU320,
CU320‑2
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).
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.

The minimum interval between two
measurements is 3 position control cycle
clocks (max. 2 edges per measurement).
