Abstract

A file obtained by converting event information into information in RSS or Atom format is held in a web server. The file is periodically read and displayed by using an RSS reader. A general web server and a general RSS reader can be used, and since HTTP is used, an existing security technique such as SSL can be used.

Claims

1. An information delivery system, comprising:

an information conversion section which converts information into information in a format capable of being delivered by using HTTP (Hyper Text Transfer Protocol), and generates a file having the converted information;

a web server which holds the file generated by the information conversion section; and

a reader which reads from the web server the file generated by the information conversion section, and displays the read file.

2. The information delivery system according to claim 1, wherein the format is RSS (Rich Site Summary), and

the reader can read the file in the RSS format.

3. The information delivery system according to claim 1, wherein the format is Atom, and

the reader can read the file in the Atom format.

4. The information delivery system according to claim 1, wherein the information is event information or an alarm.

5. The information delivery system according to claim 1, wherein the information is a daily report, a weekly report or a monthly report.

6. The information delivery system according to claim 1, wherein the information is operation information of a device in a control system.

7. The information delivery system according to claim 1, further comprising:

an event logger in a control system,

wherein the information conversion section receives the information from the event logger and converts the received information to the information in the format capable of being delivered by using the HTTP.
