PowerFlex 753 Communication

Hello,   I am trying to interface with some Powerflex 753 VFDs using a PCCC datalink.  I am able to successfully write to N42:3 to set my timeout settings.  I can read from N45:0 through N45:3 to get the status and drive hertz feedback.  However, when I try to write to N45:0 I receive "Extended STS Error: Address does not point to something usable.  I have the drive setup in CCW and am able to start it fine so I know it is functional.  Any thoughts?   Thanks for your time

Solved this.  I need to write to N45:0 and N45:1, all 32 bits.  Does not work if I only try to write the first 16 bits or an individual bit.
