To operate any drive and view its status using the data table addresses,
Human Machine Interface devices (PanelView, and so forth), or a ladder
logic program, you will need to create descriptive controller data table
addresses (Table 5.U
and Table 5.V) and a ladder logic program that will
pass the controller address data to the program data table addresses.

Status/Feedback Ladder Logic Program

Command/Reference Ladder Logic Program
Important: In addition to the Run mode for the processor, the scanner also
has its own Run mode. To change the scanner mode from IDLE
to RUN, set Bit 0 in data table address O:e.0, where e = the
scanner slot number. For this example, we set Bit 0 in data table
address O:1.0.
An example ladder logic program that uses these descriptive controller data
table addresses and passes their data to the descriptive program data table
addresses is shown in Figure 5.20
and Figure 5.21.
