PLC-5 Controller Example Single Read Response Data
In this specific N150:6 message example, we use the data table address in
Figure 6.28 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.
Figure 6.28 Example Single Read Response Data File
Figure 6.29 shows example ladder logic to correctly format the three
possible data types for read messages of different parameter types in the
PLC-5 controller.
