ipRoute Use Cases

Router between IEC 870-5-104 SCADA system and IEC 870-5-101 RTU for decentralized applications

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.

Central Router for coupling of IEC 870-5-101 substations to a SCADA system over OPC interface

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.
