Overview

The T9110 processor module is the central processing unit of an AADvance® controller. It performs the following tasks:

• Execution of the AADvance Safety Kernel to solve application logic.
• Interfacing with controller I/O modules, reading and processing input data, and writing output data.
• Communication with other processor modules, both locally and across the control network.
• Initiation of periodic diagnostics for the controller.
• Communication with other systems such as HMIs.
• Message encapsulation and verification for secure channel communication to other nodes.
