L_MC1P - MC_Touchprobe: Sometimes, single measurement with TouchProbeEdge=6 does not work (corrected from V03.17.00)

Corrected from:
Library: L_MC1P_MotionControlBasic (FAST Motion) V03.17.00.226
             (update via package manager)

Response of the new version:
The described function restriction is remedied now.
 
 
What happens?
Under certain conditions, the MC_Touchprobe FB does not work correctly.
No measured value and no 'xDone' signal is reported.
 
When does this behaviour occur?
  • TouchProbeMode = 1  (single measurement) and
  • TouchProbeEdge = 5   (first positive and then negative edge) or
  • TouchProbeEdge = 6   (first negative and then positive edge)
Which products are affected?
Library:  L_MC1P_MotionControlBasic (FAST Motion)
                (contained in the PLC Designer)
 
Short-term measures:
Use the TP operating modes TouchProbeEdge = 1 or 2 instead of TouchProbeEdge = 5 or 6 and simulate the evaluation logic in the application. 
 
Evaluation/recommendations:
A short-term remedy is available.
