L_TT1P_ElectricalShaftPos: MP04_lrSetClutchPos is not updated in the disengaged state (eliminated from V3.12)

Eliminated from:
L_TT1P_TechnologyModules_LM V3.12.0.9
 
Behaviour of new version:
With the release of the technology module (input Enable = TRUE), the measurement point MP04_lrSetClutchPos is updated cyclically.
 
 
What happens?
The position of the measuring point MP04_lrSetClutchPos does not change when the master position changes.
When does this behaviour occur?
The behaviour occurs in the Ready state when the clutch of the technology module is disengaged.
 
Which products are affected?
L_TT1P_ElectricalShaftPosState and L_TT1P_ElectricalShaftPosHigh function block from L_TT1P_TechnologyModules_LM library (V3.10.0.8 and higher)
 
Short-term measures:
Calculate the clutch-in position by adding MP03_lrSetGearBoxPosOut + OP01_lrOffset (in this way, MP04_lrSetClutchPos is calculated as shown in the signal flow diagram.) 
  
Evaluation/recommendations:

The function restriction concerns direct clutching-in. Here, the slave drive is positioned from the Ready state to the position of "MP04_lrSetClutchPos" to clutch in hard. This is, however, not possible because measuring point 4 does not output a valid position in the Ready state.
With the above described short-term measure, the clutch-in position can be calculated outside the TM.
The function restriction will be remedied as soon as possible.
