Siemens SIPROTEC 4 Manual

Remote Control SIPROTEC 4 via Ethernet-Modems 7XV585x and 7XV5655
General
In principle the scope of functions of Ethernet-Modems correspond to the already known analog or
digital telephone modems. Instead of the analog or digital telephone network, the transmission
medium is the well-known Ethernet. For this purpose, the data received at the RS232-interface are
packed into a TCP/IP-protocol and unpacked again at the opposite end for output on the RS232-
interface .Instead of a telephone number, the connection is established from the calling Ethernet
modem (office modem) by selection of an IP address.
This method allows for the simple handling of Ethernet modems by the protection communication
program DIGSI 4 if the following application guidelines are strictly adhered to.
The example outlines a small private network with free IP addresses. The operating PC with
Windows XP and DIGSI 4.50 in this case has a fixed IP address 192.168.10.100. The office modem
has the IP address 192.168.10.161, the substation modems 192.168.10.153 and 192.168.10.154.
Note: This application guide only serves as a additional user information and assumes that the user
has knowledge of the general application guide for the product and its basic functions as described in
the manual.
Approach:
•
• Installing modem driver in Windows
•
• Configuring modems with the configuration tool
o Selecting basic data (IP-address and name) of the office modem
o Selecting basic data (IP-address and name) of the substation modem
o Integration of-PC and Ethernet-Modems into the Ethernet
o Selecting the communication parameters (Baud rate, data format etc.) of the office modem
o Selecting the communication parameters (Baud rate, data format etc.) of the substation
modem
•
Inserting telephone directory and modems in the substation manager of DIGSI 4
o Insert telephone directory with IP addresses
o Insert office and substation modem with settings
o Insert modem connection
•
Establish the modem connection
o Start the connection
o Check the "number" to be dialled (IP address), correct of necessary
o Check the connection in the report window
o Establishment of connection to the protection device
