Application in Substations
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 used to link virtual COM port with the IP
address of a Serial Hub. Using DIGSI 4 it is then possible to operate 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 optical). The serial
data are converted to the UDP protocol with error detection and correction as useful data in
the Serial Hub and transmitted via the TCP/IP Ethernet network.
The hub meets the requirement for standard compliant, 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 in blocks. Both full-
duplex and half-duplex data transmission (RS485) are possible. The 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 included in the
scope of supply.
