The Allen-Bradley 1756-EN2F is a part of the ControlLogix Communication Module series. It is an EtherNet/IP (Ethernet Industrial Protocol) interface Communication Module. It supports general messaging, real-time I/O messaging, and information exchange for applications like Real-Time Control, Time Synchronization, and Motion. The 1756-EN2F bridge also has a CIP safety standard for allowing simultaneous transfer of safety and control data and diagnostics information. It uses advanced communication chips and physical media.
The 1756-EN2F Module has 100 Mbps EtherNet/IP communication rates and uses fiber. It supports 256 Logix and 128 TCP/IP communication connections. It can support a maximum of 8 axes for integrated motion on the Ethernet/IP Network. It draws 1.2 A current at 5.1V DC and 3 mA at 24V DC. It has a maximum power dissipation of 6.2 W and thermal dissipation of 21.28 BTU/hr. It can be installed in any ControlLogix Chassis slot. For wiring, it uses unshielded RJ45, category 5, twisted-pair cable connectors to interface with the controller. The 1756-EN2F bridge is configured using RSLinx software to be used at the workstation. To operate EtherNet/IP network parameters such as IP address, Subnet masks, Gateway etc. must be defined.
The 1756-EN2F bridge has various functions like providing support for messaging, distributed I/O, and tags. It encapsulates messages within standard TCP/IP protocol. ControlNet and DeviceNet network protocols allow it to share a common application layer. It does not require any scheduling or routing table to store information. Other features include explicit protected mode, Electronic keying, Device Level Ring Network, and Parallel Redundancy Protocol Network support.
