Important: When using a 20-COMM-L adapter with a PowerFlex
750-Series drive, the upper word (bits 16…31) of the Logic
Command and Logic Status words are not accessible and
cannot be used. Only when using a PowerFlex 750-Series drive
with a 20-750 communication Option Module (or the
PowerFlex 755 drive’s embedded EtherNet/IP adapter) is the
upper word accessible and used.
