SLC 500 Controller Example Write Single Request Data
In this message example, we use the data table address in Figure 6.56 to
store the request value (10.0 sec.) that was written to drive parameter 140 -
[Accel Time 1]. To determine the data type for the parameter and its
required scaling, see the specific drive documentation.

Figure 6.57 shows example ladder logic to correctly format the three
possible data types for write messages of different parameter types in the
SLC 500 controller.
