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.
Table 5.U SLC 500 and Program Data Table Address Descriptions for Example Logic
Status/Feedback Ladder Logic Program
Table 5.V Program and SLC 500 Data Table Address Descriptions for Example Logic
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
.
