Measurement signal via HLI Control Unit (P-AXIS-00257)
With this parameter it is possible to determine that the probing signal is read from the HLI via the control unit MCControlBoolUnit_ProbingSignal and not via the cyclic drive interface. See also [HLI]. The probing value is the actual value now of the occurrence of the probing signal.
Variable name | Type | Permissible range | Axis type | Dimension |
probing_signal_via_plc | BOOLEAN | 0 / 1 | T, R | ---- |
 | Caused by the scanning of the probing signal in the cycle time of the PLC the accuracy of the probed value is less than the accuracy achieved by using drive internal probing latches. |
Dependend on the drive types following measurement methods are possible:
