We live in a very imperfect world. Sometimes there are dedicated wires for device communication. If not wireless communication can be used. Unfortunately wireless communication has limitations too. Building shadows, thick stone-walls and metal cabinets, can stop it. Interference and security can also be an issues.
Then the only communication media left is the existing power-wires in buildings and streets. Narrow-band Power Line Communication (N-PLC) has been known for decades, but also known for being unreliable and complex to use.
We have been using a little known N-PLC technology for over 10 years that stands out when it comes to reliability, range and noise immunity.
This plug-in implements that technology. DINGO software stack implements a so called APDU-to-APDU BACnet gateway for PINGO. By that, devices connected over the power-line ca be seen as BACnet devices. Thereby we hide the N-PLC complexity and make it transparent.
