When using a 7XV5655-0BA00 Serial Hub with a fixed IP address, one or more
®
SIPROTEC protection units can exchange serial data via an Ethernet network.
On the operating PC, a configuration tool is applied to link a virtual COM port with the IP
address of a Serial Hub. The use of DIGSI 4 enables the operation of all protection units
connected to the Serial Hub via the virtual COM port.
The protection unit is connected to the Serial Hub via its serial interface. The serial
interface types available are RS232 or RS485 (same connector), and FO (fibre optic
cable). The serial data is converted to the UDP protocol with error detection and
correction in the Serial Hub and transmitted via the TCP/IP Ethernet network.
The hub meets the requirements for standard compliance, uninterrupted transmission of
serial DIGSI or IEC 60870-5-103/101 frames via the network by listening into the serial
®
frame traffic and sending the serial IEC telegrams via the Ethernet. packed into blocks.
Both full-duplex and half-duplex data transmission (RS485) is possible. Serial control
lines are not supported. The Serial Hub can be configured with password protection.
Configuration of the Serial Hub is performed using the configuration tool which is
included in the scope of supply.
