Global measuring

With global measuring, the current actual values of one or more encoders are measured with
positioning accuracy with a signal edge on the relevant input in order to determine lengths or
distances from these (possible with any encoders present in the project). Up to two edges can
be measured for each position control cycle clock of the Measuring Input TO.
The assignment of the inputs is not fixed, and the special use is activated via the HW address
when the Measuring Input TO is configured.
Note
Global measuring is only possible for measuring inputs with time stamp. Hardware for
measuring inputs (Page 132)

5.3.7.1 Global measuring on TM15/TM17 High Feature
Description
Digital inputs are available for connection of measuring inputs on the TM15 and TM17 High
Feature Terminal Modules. These can be used for one-off or cyclic measuring. Cyclic
measuring is only supported by the TM17 High Feature.
Note
For more information about the Measuring Input TO on Terminal Modules, see the
TM17 High Feature Terminal Modules Commissioning Manual.
