Description

The T9110 processor module is the central processing unit of an AADvance controller. The processor module carries out the following critical process and safety controller tasks:

Execution of the AADvance Safety Kernel to solve  application logic Interfacing with the 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

The processor module is galvanically isolated from external power supplies and data links so that any faults developed in the

field cannot cause the module to fail. The module will continueto operate in the event of failure of one of its dual redundant
24V dc power supplies. The module incorporates under- andover-voltage protection for its internal power supplies, which
provide a ‘power valid’ signal to the modules own diagnosticsmicroprocessor.

A processor module has two functionally independent,electrically isolated Ethernet ports. Each port is separatelyconfigurable for multiple protocols such as Modbus RTU, Open
Modbus/TCP and proprietary AADvance protocols, and its datais available to every processor in the controller.

In addition to the front panel LEDs a Fault Reset button isprovided for the user to reset any fault indications on an I/O module before the controller is restarted.

Two serial communications ports per processor are provided for Modbus RTU slave communications. These ports are also functionally and electrically isolated from each

other. They support RS-485 (4– and 2–wire) communications and can be configured to support asynchronous data rates from 1,200 to 115,200 baud.
The processor periodically initiates internal diagnostic tests which, together with a watchdog circuit, monitor the processor internal performance. If the tests detect a

serious fault, the processor module will shut down. A controller can use one, two or three processor modules. Using two or three processor modules provides a fault
tolerant processor architecture.
