MODULE OPERATION

Web Server Function

3

3-14

The Web Server Unit’s Web server function enables operations such as PLC monitoring using a Web
browser with Java applets.

■

PLC Operand Monitor

A PLC operand monitor is provided as a sample program. The PLC operand monitor is not installed in the Web
Server Unit with the initial settings at time of factory shipment. You must upload the sample PLC operand monitor
from the CD-ROM provided.

●

System Configuration Example

First make the network settings, then connect the Web server to a PC with a Web browser using a LAN or cross
cable. When monitoring, MicroSmart should be connected to the Web Server Unit and activated.

The PC must be able to run a Web browser (such as Internet Explorer), and JavaScript and Java applets must be
enabled.

●

Web Browsers

Confirmed Web browsers:

Internet Explorer 6.0, Netscape 7.1
* The Java VM running environment is required.

●

Uploading PLC Monitor Sample Screen

How to upload the PLC monitor screen is described below. At time of factory shipment, the PLC monitor screen is
not installed in the Web Server Unit. (Use the Java Applet Monitor from the CD-ROM.)
Due to restrictions on server file volume capacity, the System Setting Screen and Java applet monitor can’t coexist.

How to upload the sample program (Java applet) is described below, using Internet Explorer 6.0 as an example.

1.

Start Internet Explorer.
