Using primary and backup adapters for the 1756-EN4TR ControlLogix EtherNet/IP communications module lets industrial producers improve their network resiliency. This new redundant-adapter functionality is provided through a recent firmware update to the communication module.
- No single point of failure: When used with ControlLogix controllers and redundant switches, the communication module is no longer a single point of failure, which improves uptime and productivity in continuous process applications like oil and gas
- Architecture options: The firmware enhancement can be used with a single ControlLogix controller or redundant controllers, or with star or Device Level Ring (DLR) architectures, giving users design flexibility
- Ease of modification: An existing 1756 I/O chassis can be modified for redundant adapters, using Slots 0 and 1
The 1756-EN4TR communication module implements network-based access control for users, devices and networks in a 1756 ControlLogix chassis. The module can increase performance in networked operations, with 1-Gbit/sec communication speeds and the ability to support future network or infrastructure expansions.
