SLC 500 Controller Example Get Attribute Single Response Data
In this message example, we use the data table address in Figure 6.60 to
store the response value (0.13 amps) that was read from drive parameter 003
- [Output Current]. To determine the data type for the parameter and its
required scaling, see the specific drive documentation.
