Abstract

In an industrial automation network, several HMI (Human Machine Interface) panels operating for commissioning the plant are used. Depending on the size of the plant, the number of operating HMI panels varies. Managing the alarms, critical data generated by each of such HMI devices needs immediate notification and attention of the concerned staff for constant operation of the plant. Additionally, all connected HMI panels have to be notified about critical information based on the feed data received from another HMI device at run time, which needs supervision from the plant operator.

Managing HMI Machine Alarms, Critical Data, Recipes and Production Status through RSS Feeds

Idea: Paranthaman Ethiraj, IN-Bangalore; Sanjay Bindingnavile Raghavan, IN-Bangalore

In an industrial automation network, several HMI (Human Machine Interface) panels operating for commissioning the plant are used. Depending on the size of the plant, the number of operating HMI panels varies. Managing the alarms, critical data generated by each of such HMI devices needs immediate notification and attention of the concerned staff for constant operation of the plant. Additionally, all connected HMI panels have to be notified about critical information based on the feed data received from another HMI device at run time, which needs supervision from the plant operator.

Up to now, email notification and SMS (Short Message Service) is an existing solution to this problem. But the email notifications from multiple HMI machines are often disorganized and can be confusing so that they are often left unread.

The idea is to use Internet RSS (Really Simple Syndication) feeds technology. Using this technology, a list of HMI alarms, critical data, recipes and the production status of the plant can be distributed to a wide number of people through the Internet. The RSS information can be placed into a single file on a website in a manner similar to normal web pages. The information is coded in XML (eXtensible Markup Language) computer language for use by a program and not by a person like a normal web page. Such a special computer program is called RSS aggregator. It allows automatically to access the RSS feeds of company websites and to organize the HMI alarms. Sometimes RSS feeds and aggregators are also called RSS channels and RSS readers.

RSS provides a basic methodology to realize its notification. It is made up of a list of alarms or critical data presented automatically in order from newest to oldest, so it is possible to track changes. Each item usually consists of a simple title describing the alarm. Also, a more complete description and a link to a HMI machine are given. The presentation of the RSS content takes place in the RSS aggregator, which also can be just the web browser. RSS aggregators automatically check series of RSS feeds for new HMI alarms steadily. They detect the new alarms and present them all together to the user in a compact and useful manner.

Once the company URL (Uniform Resource Locator) for the HMI panel is created, the address can be provided to an RSS aggregator program that monitors and a...
