26 Communicate over Networks

1768-EWEB Web Server Module

The 1768-EWEB EtherNet/IP web server module supports:

• the bridging and routing of messages, but no I/O control.

• data access (read and write) to controllers via a standard web browser.

• custom web pages.

• email.

• raw, open-socket interface.

In this example:

• you can route messages, upload/download programs, and flash upgrade

modules by using the web server module as part of the communication

path to access the target device.

• you can view and modify data that resides in a 1768 CompactLogix

controller via a standard web browser.

• you can create custom web pages that are tailored to your application.

Use ASP functions to populate your web pages with live controller data.

• you can send an email initiated by a Logix controller via a MSG

instruction.

• you can open TCP or UDP communication links to other standard

Ethernet devices via open sockets.
