COMM-D would have a total of 40 bytes of I/O mapped in the DeviceNet
scanner. The I/O Image table for a ControlLogix system is shown.
1
The speed reference comes into the 20-COMM-D as a double integer. The PowerFlex 700S firmware automatically converts that
speed reference into floating point, so that parameter 20 [Speed Ref DPI] is a floating-point value.
1
Bits 0-15 only of parameter 155 [Logic Status] appear in the Input Image table of the ControlLogix controller.
2
The speed feedback sent from the PowerFlex 700S to the 20-COMM-D is not affected by parameter 73 [Spd Fdbk Scale].
Furthermore, the PowerFlex 700S automatically coverts parameter 72 [Scaled Spd Fdbk], which is a floating-point parameter, to a
double integer before the value is transferred to the 20-COMM-D.
