Get Attributes Scattered Example
The Get Attributes Scattered service can be used with the DPI Parameter
object to read the value of more than one parameter with a single
message instruction.
In this example, a read of PowerFlex 70 drive parameters 1 - [Output
Freq], 3 - [Output Current], and 6 - [Output Voltage] is being performed.
The Message Configuration screen in RSLogix 500 for this example is
shown in Figure 5.9
. It is assumed that the 1769-SM1 occupies slot
number 1, and that the PowerFlex 70 drive is connected to the 1769-SM1
channel 1.
