Network Master

Network Master
The Network Master displays data in real-time and
provides a summary of each connected device.
The collected data is also forwarded to traditional HMI programs.

      A modern electric power distribution substation may contain many Intelligent Electronic Devices (IEDs) from different manufacturers and each may require a different communications protocol.  Whaleback designed and implemented the software for a multi-threaded Windows-based "Network Master," which communicates with multiple devices so that data can be consolidated and converted into a common format.  The Network Master also communicates with third-party Human Machine Interfaces (HMIs) and Supervisory Control And Data Acquisition (SCADA) systems.  In order to accommodate customer preferences for various commercial HMIs, Whaleback isolated the interfaces into replaceable Dynamic Link Libraries (DLLs) so that new interfaces can be supported without changing the base program.  The fault-tolerant design also allows for a backup master running identical software to take control automatically in case of hardware failure.

      The Network Master is part of Substation Integration software.

SI Bus
Substation Integration (SI) Network.
The Network Master manages the SI Bus and communicates with additional interface processors.
RTU
Remote Terminal Unit (RTU).
The principal engineer for Whaleback Software, Inc. also designed and implemented the software running in this RTU that communicates with the Network Master.  The RTU design allows for the "hot swapping" of processor and I/O cards.
