Appendix: Overview of the DMAT
The Drives and Motion Accelerator Toolkit DVD, publication IASIMP-SP017, was developed around a modular concept.
Modularity lets you decide which components to incorporate into your machine, providing greater flexibility and a custom fit. The
preconfigured logic is specifically designed around this modular concept and consists of three main logic module types.
Logic Module Overview
• Machine
o The machine module contains the high level control for the entire machine. The machine module was built
around a simple state machine that you can customize to fit most applications. The machine module
broadcasts out commands and receives feedback information from each of the application and device
modules. Based on the feedback information, the machine will react accordingly.
o In addition, the machine module provides a high level interface with the HMI, accepting commands like Start,
Stop, and Clear Faults. It provides status info to the HMI terminal like current state of the machine (for
example, RUNNING versus STOPPED).
• Application
o The application modules contain all of the application specific code. This is where a majority of the
customizing is expected to occur and is essentially a programming space where you spend a significant
portion of your efforts to develop proprietary logic specific to your application.
• Device
o Device modules contain all of the logic to control the essential functions required by the device. This logic
reduces the programming effort required by most applications providing more time for the proprietary logic
needed for the application.
o Typically, the device module consists of a physical drive, but could also consist of a virtual or feedback-only
axis. Device modules can also consist of multiple devices (for example, a drive) and perhaps a feedback
device (for example, a sensor).
