5.2.4
Measurement
The measuring process is divided into one-time and cyclic measurement modes. The operating
mode is distinguished using two separate program commands.
Table 5-3
Overview of one-time and cyclic measurement functions
Measurement once
Cyclic measurement (global measuring inputs only)
As of version V1.0
As of Version V3.2
Call up with _enableMeasuringInput command.
Call up with _enableMeasuringInputCyclic command.
Measurement jobs must be issued individually for each
measurement.
Measuring is activated just once and runs cyclically until
deactivated with _disableMeasuringInput.
Several interpolation cycle clocks between two
measurements
Up to two edges can be measured in each processing cycle
clock of the measuring input TO (IPO interpolation cycle
clock, IPO_2 interpolation cycle clock or position control cycle
clock). The minimum distance between two measurements
in SIMOTION D410-2, D4x5, D4x5-2 (X122/X132) onboard,
CX32, CX32-2 and CU310/310-2/320/320-2 is 3 position
control cycle clocks. The measured values must be read from
the user program before they can be overwritten by a new
measurement.

For hardware for local and global measuring inputs, see
Hardware for measuring inputs (Page 132)
Supported by:
For hardware for global measuring inputs, see Hardware for
measuring inputs (Page 132) (excluding TM15)
Optional measuring range is possible.
One measuring range can be defined as of V4.0.
Prior to V4.0, measuring range for TO cannot be configured
(must be solved in the application).
5.2.4.1
One-time measurement
In one-time measurement mode, the measured result must be waited for. On its occurrence,
the measuring process is terminated.
