Chapter 6 Using Explicit Messaging

MicroLogix 1100/1400 Controller Example Scattered Read Response Data

In this message example, we use the data table addresses in Figure 72 to store the

response values that were read from the requested drive parameters.

Figure 72 - Example Scattered Read Response Data File for PowerFlex 7-Class

Drive

In this example, the parameters have the following values.

MicroLogix 1100/1400 Controller Example Ladder Logic Program to Write

Multiple Parameters Using Generic Get/Set Attribute Service

A Custom scattered write message is used to write to multiple parameters. This

write message example writes the following values to 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 for explicit messaging.
