Data exchange between the two control stations Karlsfeld and Lehrte, Germany, was
implemented with our ipRoute router in redundant operation. The software was
extended to meet all project-specific requirements.
Communication between the router and Karlsfeld control station uses
IEC 60870-5-101 in balanced mode on two separate lines.
Line 1 transmits messages and measured values from Karlsfeld control
station to the router and set points from the router to Karlsfeld
control station. With respect to Line1, the router behaves like a
Line 2 passes messages and measured values from the the router to
Karlsfeld station and set points from Karlsfeld control station to the
router. In this respect, the router behaves like a 'slave'.
Communication between ipRoute and Lehrte control station also
runs on the
IEC 60870-5-101 protocol in balanced mode. In this context, the router is
both master and slave.
After delivery, the installation was extended and another function
added. Set points from Lehrte control station (in control direction) are
converted to measured values and passed on to the RTU channel.
