The ABB-1756-EN2T(corresponding to Rockwell Allen-Bradley 1756-EN2T)is a high-perbance Ethernet communication module for Rockwell’s ControlLogix PLC systems,enabling seamless data exchange between controllers and industrial devices.Equipped with two 10/100Mbps auto-sensing Ethernet ports,it supports both real-time industrial protocols(EtherNet/IP with CIP Sync,CIP Motion)and standard TCP/IP/UDP/IP,making it compatible with Rockwell devices(e.g.,1794-AENT I/O stations,PanelView HMIs)and third-party equipment(ABB drives,Siemens sensors).Its dual-port design allows network isolation(separating control and monitoring networks)or redundant operation(automatic port switching in≤100ms),ensuring high availability for critical applications like chemical reactors and power substations.With ultra-low latency(≤10ms for EtherNet/IP I/O)and CIP Sync time synchronization(±1μs accuracy),it meets the real-time requirements of multi-device coordination(e.g.,automotive welding lines).The module supports remote configuration,firmware updates,and diagnostics via Ethernet,reducing on-site maintenance costs.Certified to CE,UL,and optional ATEX standards,it operates reliably across 0°C to 60°C,making it a trusted choice for distributed industrial automation.
