LS_ParReadWrite: Read value remains optionally pending
Function extension:
Via C1098/x bit0 and bit1, you can select the behaviour of the wOutLWord and wOutHWord outputs:
Bit 0=TRUE: The last value successfully read remains available at the wOutLWord and wOutHWord outputs until the next value has been read successfully. If an error occurs, the output values will be set to 0.
Bit 0+1=TRUE: The last value of the outputs will be retained even if an error occurs.

Application:
With the Lenze setting C1098/x bit0 and bit1 = FALSE, the wOutLWord and wOutHWord outputs are set to zero as soon as the bExecute input changes from TRUE to FALSE. If the application requires the last value read to be retained, the advanced option can be used.
