Configured for managed Ethernet communication in Stratix industrial network systems, the Allen-Bradley 1783-EMS08T (1783-EMS08T Managed Ethernet Switch) provides direct physical network switching execution for EtherNet/IP and TCP/IP communication environments.

Model Identification

The 1783-EMS08T is an Allen-Bradley Stratix Ethernet switch with 8 copper ports and optional fiber optic connectivity. It supports managed network functions including VLAN-related industrial communication management, DHCP, BOOTP, FTP, HTTP, Telnet, IGMP, SMTP, and EtherNet/IP protocol communication.

Hardware Specifications

EtherNet/IP Network Characteristics

The 1783-EMS08T operates as a managed Ethernet communication device within Allen-Bradley industrial control networks. The switch supports EtherNet/IP deterministic communication requirements through managed switching functions and protocol handling.

The Stratix platform provides compatibility considerations for PLC-based Ethernet architectures, allowing communication paths between ControlLogix, CompactLogix, PLC-5 migration systems, and industrial Ethernet devices.

Network configuration functions include TCP/IP addressing services, DHCP and BOOTP assignment, IGMP support for multicast traffic management, and HTTP/Telnet access for switch configuration.
