Introduction
The EDS-405A/408A-PN series are 5 and 8-port managed Ethernet switches with PROFINET capabilities, designed for easy integration into Simatic Step 7 engineering tools. These switches facilitate configuration and monitoring for automation engineers through Step 7 and automation HMIs.

Specifications
The switches feature fast booting, Turbo Ring, and Turbo Chain fast-recovery technology to enhance PROFINET network performance. They support management functions like IGMP snooping, VLAN, QoS, port mirroring, SNMP, bandwidth management, and alerts via email or relay.

• IGMP snooping and GMRP for multicast traffic filtering
• VLAN support for network planning
• QoS for increased determinism
• RMON for network monitoring
• SNMPv1/v2c/v3 for network management security
• Port mirroring for debugging

Features and Benefits
PROFINET is enabled by default, supporting I/O parameters, cyclic data, DCP, DHCP, and compatibility with PROFINET Real-Time. The switches include GSD files and SIMATIC STEP 7 device icons.

Technology
Standards include IEEE 802.3, 802.3u, 802.3x, 802.1D-2004, 802.1w, 802.1p, and 802.1Q. Supported protocols include IGMP, SNMP, DHCP, TFTP, SNTP, SMTP, RARP, RMON, HTTP, Telnet, Syslog, BootP, LLDP, PROFINET, EtherNet/IP, Modbus/TCP, IPv6, and NTP.
