3.7.1 Interconnection, Connection - Measuring sensors
• In S7T Config, the "Measuring sensor" TO can only be inserted at the "Axis"
and "External encoder" TOs.
• Each "Measuring sensor" technology object only has a single axis or a single
external encoder assigned to it.
• The measuring sensor input must be located either at the corresponding drive
component, or at a TM15/TM17 High Feature module. The measuring sensor
inputs are indicated specially at the corresponding hardware, or have to be
configured there as measuring sensor inputs. The number of measuring
sensors available depends on the hardware used.
Other digital inputs at DP(DRIVE)can not be used as measuring sensor inputs.
The digital measuring sensor input used for the "Measuring sensor" TO is
configured for the TM15/TM17 High Feature module in S7T Config.
• Several "Measuring sensor" technology objects can be configured for a
positioning axis, synchronization axis or for an external encoder.
However, "Measuring sensor" technology objects may not be active
simultaneously.
• Measuring sensors may not be configured for use with virtual axes.
• Measuring sensors can not be configured for operation on velocity-controlled
axes.
Enabling / disabling
Measuring sensors are enabled/disabled by means of FB "MC_MeasuringInput".
