Which products are affected?
LenzePLCToolbox.lib and LenzePLCToolbox0104.lib libraries
What happens?
By means of the L_TBSquareWave function block from the LenzePLCToolbox library a Boolean square wave signal with variable high/low time can be generated.
The low time of the square wave signal generated is one PLC processing cycle longer than the low time applied at its function block input wTimeLow.
When does the problem occur?
The response described before always occurs if the L_TBSquareWave function block is used.
Possible diagnostics?
None.
Short-term measures/recommendations?
None.
Evaluation:
The low time of the square wave signal which is generated by the L_TBSquareWave function block is longer than the selected low time. Up to now, the function block has rarely been used in applications.
