Set Attributes Scattered Example
The Set Attributes Scattered service can be used with the DPI Parameter
object to write the value of more than one parameter with a single
message instruction.
In this example, a write of PowerFlex 70 drive parameters 140 - [Accel
Time 1], 142 - [Decel Time 1], and 100 - [Jog Speed] is being
performed.
The Message Configuration screen in RSLogix 500 for this example is
shown in
Figure 5.12 . 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.
Refer to Table 5.A on page 5-11 for a description of the content in each
