Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 64)

4-4 Understanding the I/O Image
The Logic Command is a 16-bit word of control data produced by the
controller and consumed by the 1769-SM2 module. The Logic Status is a
16-bit word of status data produced by the 1769-SM2 module and
consumed by the controller.
This manual contains the bit definitions for compatible products
available at the time of publication in
Appendix D . For other products,
refer to their documentation.
The Reference (16 bits) is produced by the controller and consumed by
the 1769-SM2 module. The Feedback (16 bits) is produced by the
1769-SM2 module and consumed by the controller.
Valid Reference/Feedback values for PowerFlex 4-Class drives are:
Using Logic Command/Status
Using Reference/Feedback
Size Drive Valid Values (1)
(1) The Reference/Feedback for a PowerFlex 4-Class drive is set in Hz and
not in engineering units like PowerFlex 7-Class drives. For example,
“300” equates to 30.0 Hz (the decimal point is always implied) for all
PowerFlex 4-Class drives—except PowerFlex 400 for which “3000”
equates to 30.00 Hz. In all cases, a minus value equates to reverse
motor direction, and a plus value equates to forward motor direction.
