L_TT1P_PickAndPlace: Unexpected error message "AxesGroupExternalStop" (eliminated from V3.16.0)

What happens?
After setting xPathStop, the technology module changes to the ERROR state and the ID "AxesGroupExternalStop" is output.

When does this behaviour occur?
1. xExecPickandPlace = TRUE
2. xPathHalt = TRUE --> No error. The technology module changes to the "STOP" state.
3. xPathStop = TRUE --> Error message "AxesGroupExternalStop". 

Which products are affected?
L_TT1P_PickAndPlace from the L_TT1P_TechnologyModules_LM library (V3.14.2.54 and higher)

Short-term measures:
The above-described error does not occur in reverse switching sequence (xPathStop first, then xPathHalt).

Evaluation/recommendations: 
The xPathStop function is provided. The function restriction occurs in the above-described special case if the xPathHalt function has already been active before activating xPathStop. In this case, the technology module changes to the error state. The path is, however, stopped despite the error state.
