What signal is transmitted in the FF instrument signal line? Who has any FF-related materials that can be sent to me at 419607857@qq.com?
FF Foundation Fieldbus transmits digital signals
The foundation fieldbus should be a digital signal
This doesn’t require any special explanation, right? 1. First, there is the electrical signal. 2. It is a digital signal that complies with FF specifications. 3. There is also a basically constant direct current signal that supplies power to the two-wire FF protocol circuit. 4. There are stray signals in the circuit
Fieldbus transmitters transmit digital signals, and their communication method differs from that of analog communication: 1. In analog signal communication, one transmitter is connected to a pair of wires, whereas with fieldbus communication, multiple transmitters can be connected； 2. Analog signal communication is unidirectional, while field bus communication is bidirectional ； 3. An analog signal transmits one signal over two wires, while a field bus can transmit multiple signals.
