1. Access Control System Characterization Presenting: Ehud Bahat Amir Levy Instructor: Erez Zilber November 2003

2. Project Goal The system will remotely control and administrate devices in a CANOpen network. The system will manage users and their privileges in the network.

3. Specifications Receive events from devices and act accordingly. Send control and configuration messages to devices. Administration of the users and devices in the network. Produce reports of the system activity.

4. Inputs Events arriving from CANOpen interface: –State change in a component. –Acknowledge messages. –Message with arguments. Web administration: –Adding, removing or updating users and components. –Modify users permissions. –Report requests.

5. Outputs Sending messages to CANOpen interface: –State modification (initBus, stopBus, boot, stop, reset, reset communication). –Data messages (read, write, emergency) synchronous or asynchronous. Web administration: –Produce reports: Log of events, exceptional events and illegal events.
