Parameters, RSLogix 5000 Software, All Versions
A Scattered Read message is used to read the values of multiple parameters. Up to
22 parameters can be read. This read message example reads the values of these
five parameters.
See DPI Parameter Object on page 198 (Class code 0x93) for parameter
numbering.
Important: See Table 17 on page 106 for limitations of PowerFlex 7-Class
drives when using Class code 0x93.
