Remote control SIPROTEC 4 with EN100 over ISDN-Modem-Router
Data transmission takes place via an RDT connection of an ISDN modem with an ISDN router
and SIPROTEC 4 devices with EN100-interface.
Operation concept SIPROTEC 4 with Ethernet module EN100
The figure below displays a typical hardware structure for V4-protection devices with Ethernet-
interface in the installation. The protection devices with electrical EN100-interface are connected to
the switches via patch cables. The devices with optical EN100 module are looped into the optical
double ring in the form of a ring together with the switches.
The switches together with the protection devices constitute a local subnet (LAN) with its own
address range.
The ISDN modem router which enables the remote connection via an ISDN dial-up line to the control
centre, is also connected to the LAN with a patch cable. As a rule, the router is assigned the first IP
address, which is then the standard gateway for all users.
The connection is established by the control centre with an RDT connection in Windows XP with an
ISDN modem. The DIGSI 4 protection devices can then be operated. To connect various substations,
an RDT dial-up connection is required for each substation.

Introduction
The possibilities of remote control of SIPROTEC devices are manifold. Help regarding the selection
of “Your” remote control concept can be found in the document “Notes” in the Internet under
www.SIPROTEC.com / Applications / Remote control
This document describes the procedure for secure remote control of SIPROTEC 4 devices with
DIGSI 4 via the modems INSYS Pocket Profi ISDN (table-top device in the office) and INSYS ISDN-
router (rail mounted ISDN-Router in the substation) in detail.
The application described here was successfully tested with Windows XP SP2
and DIGSI 4.81 as well as 4.82. The following modems were used during the tests:
Office modem: INSYS Pocket Profi ISDN (desktop model with plug-in power adapter)
Substation modem: INSYS ISDN-Router (rail mounted device with external wide range power
adapter).
The modem drivers TA+POX (PPP,V.120,X.25,V.110) used here for the INSYS Pocket Profi ISDN
modem are located on the supplied CD or may be found in the Internet under:
www.SIPROTEC.com / Accessories / 7XV5820 / …
The safety concept
The safety concept regarding interference on the entire transmission line, as well as the risk of
unauthorised access to the protection devices are taken regard of with correspondingly high priority
measures.
Transmission security is ensured by an efficient error correction procedure along the transmission
line. The settings of the modems described here take cognisance of this concept.
The substation with SIPROTEC 4 devices is protected from unauthorised access by an RDT
connection with login-name, password and restricted call acceptance from specified telephone
numbers.
The most important general rules
For remote control under Windows XP Prof. only use DIGSI 4.80 + SP2,
DIGSI 4.81 + HF1, DIGSI 4.82 or newer DIGSI-versions.
Always use the modem drivers referred to in the application manuals.
These may be downloaded from the Download-Area under www.SIPROTEC.com.
Each protection device in the substation must have a distinct IP address.

Creating a project and substation in DIGSI 4
The new project in DIGSI 4 with substation files, feeder files and protection devices may be de-
archived from an archived substation or be newly created.
The procedure is described in the „SIPROTEC System Manual“.
Before the necessary settings for remote control are done, the local connection to all protection
devices via the central interface (e.g. at the LAN connection of the ISDN router) must be tested (see
Figure 1).
Please also note the detailed application examples for the structure of a local subnet in the EN100
manual under:
www.SIPROTEC.com / Prot. Devices / General Information / Communication.
Note:
•All devices require an EN100-system interface
•Each device must have a unique IP-address.

Setting the protection devices
The Ethernet-system interfaces of the SIPROTEC-protection devices must all be assigned with
different
IP-addresses. The IP-addresses of the PC’s, the routers and other devices in the network may not be
assigned again.
For the purpose of setting the Ethernet-system interface (EN100), a connection via the front interface
of the relevant device is created with DIGSI 4. Thereafter, „Object Properties…“ is opened with the
right mouse button.
In the window „Properties“ the IP
addresses of the protection devices can
be assigned under „Communication
parameters“.
The „IP address“ must be allocated in
the same subnet range as the router.
(here 192.168.20.xxx).
The „Subnet mask“ 255.255.255.0
allows for the allocation of addresses to
254 devices (incl. PC, Router, etc.).
The IP address of the ISDN router is
always used as the „Standard gateway“
All other entries should not be changed.
Close the window with „OK“ and save the settings in DIGSI and the protection devices.
