BFH Click the blue text to follow us↑↑↑↑ RS-485 is a wired transmission, so it requires a hardware transmission medium, which is essentially just two wires. The actual signal transmitted on these two wires is the same; the sender splits this signal into two, but at the receiving end, it is restored to its original … Read more
From the OSI network model perspective, fieldbus networks generally implement only the 1 layer (Physical Layer), the 2 layer (Data Link Layer), and the 7 layer (Application Layer). Because fieldbus typically includes only one network segment, it does not require the 3 layer (Transport Layer) and the 4 layer (Network Layer), nor does it need … Read more
