RS485: Serial Communication Standard for Industrial Applications

RS485 is a serial communication standard often used in industrial automation, security monitoring, and other fields for long - distance communication between multiple devices. Using differential signal transmission, it has strong anti - interference ability and long transmission distance, and can support multiple devices to communicate on one bus for distributed control systems.

RS485 Serial supports multiple devices on a single bus, making it easy to integrate into industrial and automation environments. It allows the use of multi - point communication since multiple devices can connect to one RS485 bus. This standard communicates with other devices using differential signaling, which increases the immunity to noise and further distances for transmission. In control systems, RS485 serial can link together sensors, actuators, PLCs and any other devices to enable data exchange which allows the automation and supervision of industrial processes such as a manufacturing plant or power system.

What are the advantages of RS485?

RS485 has advantages like strong anti - interference ability due to differential signal transmission, long - distance communication capability, and the ability to support multiple devices on a single bus for distributed control systems.
Typically, an RS485 bus can support up to 32 devices. However, with the use of repeaters or special drivers, the number of connected devices can be increased, depending on the specific application requirements.
In an RS485 network, devices are daisy - chained together using two wires (A and B). The positive terminal of one device is connected to the positive terminal of the next device, and the negative to the negative, following a proper grounding scheme for stable operation.
