ESERA 1-Wire Controller, 1-Wire Gateway and 1-Wire ECO
An ESERA 1-Wire controller can address up to 30 sensors, each with up to 4 measured values; larger networks are built by combining multiple bus masters and controllers.
With 1-Wire repeaters, the length of the bus system can also exceed 100 meters.
"A municipal customer uses our 1-Wire system to monitor the network infrastructure at the distribution network level," explains Andreas Geisler. "The condition of substations and cable branch points in the distribution network could previously only be verified through personal inspection.
Now that the distribution network components are equipped with sensors, a glance at the system is enough to confirm the proper condition of the distribution network hardware," Geisler illustrates. He adds, "With the increasing cost pressures on energy suppliers, sensor-supported network monitoring pays for itself very quickly."
The connection to higher-level IT infrastructure is done in such a way that the 1-Wire bus system remains unnoticed by it.
An ESERA 1-Wire controller—potentially even the Raspberry Pi-supported ESERA station—can be used with many software systems like Codesys, IP-Symcon, OpenHAB, FHEM, or NodeRed, and allows the 1-Wire infrastructure to be connected via ModBus, M-Bus, PROFINET, etc., to Siemens PLCs, WAGO systems, and others.
