Appendix B Logic Module Customization
The application and device modules interact with the state machine via their R02_Monitor and R03_Control
routines.
For example, the device modules accept commands and react accordingly. Therefore, changes to the state
machine can impact the individual application and device modules. Refer to Appendix A for more information
on the state machine and how it interacts with the application and device modules.
The core for the state machine is built around the
UDT_MachCtrl data type.
The UDT_MachCtrl data type consists of three
sub data-types that directly impact the state
machine:
• Mode = UDT_MachMode
• Command = UDT_MachCmd
• State = UDT_MachState
