The TO Measuring Input cannot be interconnected with DP I/O or integrated I/O (with the
exception of inputs of measuring inputs).
5.2.3.2 Several Measuring Input TOs on one axis/encoder (as of V3.2)
Several Measuring Input TOs can be assigned to an Axis TO or an External Encoder TO. The
number of measuring inputs is determined according to the functionality (local or global).
Local measuring inputs
For local measuring input (see Hardware for measuring inputs (Page 132)) the following
applies:
● Only two measuring inputs can be configured per axis TO or external encoder.
● Only one measuring input can be active on an axis TO or external encoder.
Global measuring inputs
For global measuring inputs (see Hardware for measuring inputs (Page 132)) the following
applies:
● More than one measuring input can be configured per axis TO or external encoder.
● More than one measuring input can be active simultaneously on an axis TO or external
As far as interconnections of measuring input TOs are concerned, one local measuring input
can be configured on an onboard measuring input and one or more global measuring inputs
can be configured and simultaneously active on measuring inputs of C240/C240 PN (B1-B4),
D4xx, D410-2, D4x5-2 (X122/X132/X142), CX32, CX32-2, CU310/310-2/320/320-2 and TM15/
TM17 High Feature.
