More than 170 RTUs, distributed across several hierarchically organized
control stations, were to be connected to the superordinate control station.
Communication on the control level is implemented with IEC 60870-5-104.
Communication between the control levels and the RTUs is implemented via IEC 60870-5-101
in balanced mode. ipXRoute (RCC or RCI), a project-specific variant of
our standard product
ipRoute, takes care of protocol conversion.
ipXRoute has been specifically designed to enable dynamic address routing.
The addresses of the subordinate systems are generated and entered into the
transmission table during runtime.
Depending on the router location, time synching is initiated either via NTP (Network
Time Protocol) or directly via the
IEC 60870-5-101 protocol.
In addition, redundant routers, stand-alone routers and dial-up routers are
The RCC interface handles the communication with the superordinate control
stations, the RCI interface handles the communication with the subordinate devices.
The superordinate control stations run on our high-performance 19" industrial
PCs, our top hat rail embedded PCs HEC (no rotating parts) are used as
hardware platform for the subordinate control stations.
