Overview
The switch is able to provide redundant topologies by the Spanning Tree Protocol (STP / RSTP / MSTP). A connection to PVST+ networks is also possible. Alternatively, the Ethernet Ring Protection Switching protocol (ITU-T G.8032 ERPS) can be used.
VLAN segments and serial data tunneling are supported.
The device can be used for converting between the serial telecontrol protocol IEC 60870-5-101 and the TCP-IP-based IEC 60870-5-104, as well as for converting between Modbus-RTU and Modbus-TCP. Ethernet may be distributed within a station through the eight RJ45 ports of the switch.
Depending on the SFP module equipped, the unit is able to span distances by fiber optic cable up to 200 km.
Features
- Power supply 24 … 60 V DC
- Option for IEEE 802.3at PoE+
