The PLC 1756-EN2F is a ControlLogix communication module. This module is used to enable Remote I/O connection, capable of acting as a communication adapter and scanner; permits data exchange between controller and visualization systems such as Human Machine Interface (HMI) or Supervisory Control and Data Acquisition (SCADA) and bridge ethernet networks to link messages from different ethernet nodes.
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. 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.
