L_MC4P_WriteParameter, L_MC1P MC_WriteParameter: Value range check incorrect for parameters of axis groups (corrected from V03.26.00)

Corrected from:
Library: L_MC4P_RoboticHandling (FAST Motion) from V03.26.00
               L_MC1P_MotionControlBasic (FAST Motion) from V03.26.00
               (Update via Package Manager)
 
Response of the new version:
L_MC1P MC_WriteParameter and L_MC4P_WriteParameter:
If the value to be written is outside the permissible value range of the parameter, a corresponding error message is now output.


What happens?
L_MC1P MC_WriteParameter and L_MC4P_WriteParameter:
The value range check of fixed-point parameters is faulty.
Values outside the valid range are not caught. This can lead to undefined behaviour.

When does the behaviour occur?
  • By means of MC_WriteParameter or L_MC4P_WriteParameter, parameters of axes or axis groups are changed from the application at runtime of the PLC and
  • they are fixed-point parameters (e.g. UINT with three decimal places), which have a value range limitation and
  • the value to be written is outside the permissible value range.
Which products are affected?
Library: L_MC4P_RoboticHandling (FAST Motion) 
               L_MC1P_MotionControlBasic (FAST Motion) 
 
Short-term measures / evaluation / recommendations:
As a remedy, parameters which are described with the FBs mentioned at runtime of the PLC should only be described with values in the valid value range.
