Industrial Automation Usage ClassesIndustrial Automation Usage ClassesSafety Class 0 : Emergency action (always critical)
ControlClass 1: Closed loop regulatory control (often critical)
Class 2: Closed loop supervisory control (usually non-critical)
Class 3: Open loop control (human in the loop)
Monitoring
Class 4: AlertingShort-term operational consequence (e.g., event-based maintenance, asset tracking)
Class 5: Logging & downloading/uploadingNo immediate operational consequence (e.g., history collection, SOE, preventive maintenance)

Mela Networks WSN SoftwareMela Networks WSN Software
• Enable users to rapidly and cost effectively deploy integrated, interoperable solutions for networked sensors across all device platforms, with centralized management and control
• Build on Open Source Tools and Spring Framework– Spring framework, modular, maximal code reuse, wired by config files– Deployable to any standard J2EE container/application server,
Apache Tomcat, Websphere, Oracle App Server, WebLogic– Hibernate and Data Access Object, support any database, mySQL,
PostgreSQL, Oracle DB, SQL Server– Java and JSP, “cross platform”– Model View Controller (MVC) pattern, separate presentation from
business logic from data, easy customization– Web services (SOAP) to interface with Enterprise applications– Structured XML, translators for any WSN vendor XML interface– AJAX, optimizing user experience
• Plug and play with legacy industrial automation protocols, e.g. Modbus
FunctionalitiesFunctionalities• Command and Control dashboard with summary
alarm status– Easily apply user-defined business rules for immediate visibility
and notification of exceptions
• Network topology– Monitor network health and connectivity
• Data analysis and graphs– Easy and intuitive data access and trending
• Configuration of device profiles and server settings– Easily configure and control a network of devices graphically
• Web Services Interface– Transform raw data into actionable events and seamlessly
integrate the events with existing enterprise execution systems.

Application RequirementsApplication Requirements• 2 years battery life (1 sec sensor sampling rate & 10 sec/packet) • High reliablity (> 99.9%)• Automatically picks clean channels to avoid interference• Edge node able to pick the best router to connect to the network• Mesh backbone should have redundancy, be self-healing• Fast reconnect time when parent down: ~ O (1) sec• Ease of deployment: automatically pick clean channels, avoid
interference• Hot standby base node to prevent single point of failure• Network provides sufficient health information, periodically & on-demand• Customer can develop its own command and control applications to
monitor the readings, configure devices through device profiles• Customer can develop sensor drivers easily• Separation of the network logic from the storage logic• Future: battery powered routers with sensors attached to them.
