The 1756-EWEB allows flash upgrades, program uploads, and downloads directly from the web interface. Custom web pages can display live controller data via the ASP function. Additionally, the module supports TCP or UDP links with other Ethernet devices.

You can send email messages using the embedded composer, triggered by a Logix controller MSG instruction. Note that all email details must be entered for each message.

The module supports up to 256 unconnected CIP messages. Half of these messages can communicate from the Ethernet port to the module or backplane, while the other half communicate from the backplane to the module or Ethernet port.

Installation is simple: align the module to the ControlLogix chassis slot, slide until it snaps into place, and connect it to the network.
