ControlLogix Controller Example Scattered Read Request Data
In this message example, we use the data structure in Figure 6.14 in the
source tag named Scattered_Read_Request to read these five parameters in
a PowerFlex 7-Class drive:
• Parameter 001 - [Output Freq]
• Parameter 003 - [Output Current]
• Parameter 006 - [Output Voltage]
• Parameter 012 - [DC Bus Voltage]
• Parameter 017 - [Analog In1 Value]
Figure 6.14 Example Scattered Read Request Data
ControlLogix Controller Example Scattered Read Response Data
The Scattered Read Request message reads the multiple parameters and
returns their values to the destination tag (Scattered_Read_Response).
Figure 6.15 shows the parameter values.
