 The M340 / M580 and Momentum Controllers, does not allow to declared a Real data type on a ODD boundary.
Since the PCFL_LKUP requires to have Real Parameter on ODD and Even boundary it is recommended to have the starting address on a Odd boundary
and re-aligh the Input to be on an ODD boundary  This logic can be used with a Quantum and Premium PLC but is not required*)

PCFL LKUP Starting address is %MW2001
