RS485 vs Ethernet: Which One is Most Used in Industry?

Ethernet (IEEE 802.3) is the most broadly used network protocol these days. It is also a serial communication standard. Since it is used in so many modern networks, the question is why hasnt it replaced RS-485 and its other variations (RS-232, RS-422). When comparing RS-485 with Ethernet both of them have advantages and disadvantages.

Wiring of RS485 Communications Networks

Ground loop currents flowing in the shield will induce noise in the communications cable. A capacitor or an RC network may be used between the other end and ground. The RS485 nodes can tolerate from -7V to +12V of common mode voltage. When this voltage is exceeded the nodes are no longer guaranteed to function and may even be damaged.
