Eliminated from:
9400 HighLine SW V08.00.24.00
Behaviour of the new version?
The POS_bdriveInTarget signal is only reset if the target window is exited or a new profile is started.
<hr>
Which products are affected?
9400 HighLine SW ≤ V07.01.06.00
Description of the problem
POS_bDriveInTarget is reset to FALSE, although the current position actual value is still within the tolerance and hysteresis window set in C02671 and C02672.
When does the problem occur?
Signal POS_bDriveInTarget is set to FALSE on a rising edge at POS_bEnable. This is also always the case if, for example, a 'wait' action appears between two 'positioning' actions in the L_PosSequencer sequence control.
Diagnostics options?
Signal POS_bDriveInTarget can be diagnosed together with POS_bEnable using the L-force Engineer oscilloscope function.
Short-term measures/recommendations?
Signal POS_bDriveInTarget can only be evaluated until the LS_Positioner is selected again.
Evaluation:
Signal POS_bDriveInTarget cannot be evaluated for a master control depending on the fieldbus cycle under the conditions described above. The function of the positioning sequence control TA is not impaired.
