Using DeviceLogix Appendix D
Figure 92 - Two Input Four Position Selector Switch Logic Map
Discrete Inputs in the Drive are used for Inputs 1 and Input 2. Output A, B, C,
and D is linked to DeviceLogix Scratchpad Registers. The scratchpad feature
allows further flexibility to modify the values of these outputs.
The resulting output can be linked to a parameter and be used to support drive
applications, such as configuring multiple preset speeds and point-to-point
positioning. In this example, it controls Preset Speed 1.
