SLC 500 Controller Explicit Messaging Using the Generic Get/Set
Attribute Service
SLC 500 Controller Example Ladder Logic Program to Read Multiple Parameters
A Custom scattered read message is used to read the values of multiple
parameters. This read message example reads the values of these five
parameters.
See DPI Parameter Object on page C-16 (Class code 0x93) or Host DPI
Parameter Object on page C-30 (Class code 0x9F) for parameter
numbering.
Important: See Table 6.A on page 6-2 for limitations of PowerFlex 7-Class
and PowerFlex 750-Series drives when using DPI Parameter
Object Class code 0x93 or Host DPI Parameter Object Class
code 0x9F for explicit messaging.
