Using the I/O Chapter 4
Tab le 6 shows the I/O image when using all 32-bit datalinks.
Using Logic Command/Status
The controller produces the logic command, a 32-bit word of control data,
which is used by the drive or bus supply. The drive or bus supply produces logic
status, a 32-bit word of status data, which is used by the controller.
When using a ControlLogix controller with the drive Add-on Profile, the logic
command word is always DINT 0 in the output image. The logic status word is
always DINT 0 in the input image.
This manual contains the bit definitions for compatible products available at
the time of publication in Appendix E
, Logic Command/Status Words:
PowerFlex 755T drives and Bus Supplies.
Using Reference/Feedback
The controller produces the reference, a 32-bit REAL (floating point) word of
control data that is used by the PowerFlex drives 755TL, 755TR, or 755TM
common bus inverter. The drive or bus supply produces feedback, a 32-bit
REAL (floating point) word of status data, which is used by the controller.
