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.
The SHDSL port can be used for interconnecting stations with a maximum distance of 25 km (copper cable with diameter of 0.8 mm). The SHDSL interface can be connected to any EDS500 SHDSL compatible device including 560NMS24, 560NMS34 and any EFM based SHDSL device.
