PLC-5 Controller Example Single Write Request Data
In this specific N151:30 message example, we use the data table address in
Figure 6.32
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 6.32 Example Single Write Request Data File
Figure 6.33 shows example ladder logic to correctly format the three
possible data types for write messages of different parameter types in the
PLC-5 controller.
