Additional Information

The 1756-ENBT/A module is equipped with diagnostic indicators that simplify troubleshooting by providing clear status information. It is backward-compatible, allowing for the replacement of 1756-ENET modules without the need to modify existing programs. The module can function as a bridge to a ControlLogix processor when installed in a local chassis or as a Remote I/O Adapter in a remote chassis, enabling remote control and data collection. Additionally, it is web-enabled, allowing users to access module, connection, and network information remotely via a standard web browser.

For optimal performance, ensure the use of 802.3 compliant shielded or unshielded twisted pair Ethernet cables. The module’s open-style enclosure requires installation in a suitable environment to maintain specified operating conditions.
