In M340 PLC's can Web-enabled database be used to view and modify the run-time values of PLC symbols (variables) and direct addresses

How can we help you today?

FactoryCast is a software package that you use to customize a Web site on the Embedded Web Server module. The site can be accessed via a browser to view and modify data from a Modicon M340 programmable logic controller (PLC). FactoryCast provides the Web pages and Java applets you need to view run-time data from your controller. You can use the FactoryCast default Web site simply by configuring the module and accessing it with a browser over the intranet.

FactoryCast gives you two levels to customize the default Web site embedded in the PLC module.

Create a Web-enabled database to view and modify the run-time values of PLC symbols (variables) and direct addresses
Add your own Web pages to the site

For Modicon M340, the FactoryCast components are integrated as follows:

This Component...	Is Used To...
BMX NOE 0110	Store the Web site on its Embedded Server.
Unity Pro 4.0 and higher	Program the controller.

The FactoryCast Server offers run-time monitoring and diagnostics via predefined Web pages. The features available include:

diagnostic tools:
- a Rack Viewer that displays the status and configuration of the controller, embedded server module, and other option modules and I/O modules.
- an Alarm Viewer that displays application events, when diagnostic properties are enabled in the PLC application.
monitoring tools:
- a Data Editor that helps you view and modify variables (symbols and direct addresses).
- a Graphics Editor that you can use to create and display graphical objects. Each graphical object can be linked to a variable or address in the embedded server.
- a PLC Program Viewer that lets you monitor the PLC program during run-time.
