ipRoute is widely used for coupling IEC 60870-5-101
substations to one or more superordinate control stations with the IEC 60870-5-104
protocol.
Control station and substations are connected via TCP/IP and Ethernet,
which means that costly leased lines are no longer necessary for coupling
IEC 60870-5-101 substations. And a TCP/IP connection can serve several services
and devices at the same time.
ipRoute offers remote configuration and diagnosis from the
control station, substantially reducing the number of journeys to the
substation.
ipRoute is capable of delivering data to several control stations
simultaneously, numerous projects have proven the advantages of this
features (for instance Pfalzwerke).

ipRoute is also used to connect IEC 60870-5-101 based control
stations to IEC 60870-5-104 based substations.
This use offers a solution for cases where an obsolete control station needs
to communicate with new substation technologies.
Even without the appropriate infrastructure (i.e. control station and
substations are connected only via slow leased lines), this combination has
proven an effective and efficient solution.
As the different protocols may be combined in any way, even complex
architectures can be realized. For a reference see the Iran Gas Project project.

Route for dialup connections over PSTN
 |
ipRoute can also set up a dial-up connection via the
telephone network, enabling control and monitoring of remote
substations where permanent access is not needed. Connection set-up to the
substation is initiated either by the receipt of a command from the
control station or in cyclic intervals. The substation, too, can initiate
connection set-up in order to transmit data ready to be sent.
Of course, you can also combine ipRoute with ipRouteDialup.
RWE Mosel Hydro Power Stations is a good reference project for this kind of
communication solution.

Redundant Operation
 |
ipRoute can be operated in redundant mode together with
a second device. You can use either a serial interface or Ethernet to
connect the two devices. There is always one device which is active, while
the other one remains passive. Should the active device fail, the passive
one takes over the communication tasks. Which device is to be active can also
be specified at the control station.
A CS device is used to connect serial interfaces to both devices.

The combination of ipRoute and ipConvOPC offers a
smart solution for connecting visualization systems to IEC 60870-5-101
substations. With ipRoute, the usually redundant servers can still be
simultaneously supplied with data, should there be only one line for each
substation.
Communication between server and ipRoute is implemented via
IEC 60870-5-104 (TCP/IP). This means your server needs no extra upgrade with
serial interfaces (which again might reduce server availability).
Of course, ipRoute can also be operated in redundant mode,
meeting even the highest demands on availability.
