What is DH485?
DH485 is a proprietary industrial communication protocol developed by Allen-Bradley (now Rockwell Automation). It's a serial communication protocol used primarily to network Allen-Bradley programmable logic controllers (PLCs) and other industrial devices. It enables communication between PLCs, operator interfaces (HMIs), and programming terminals for tasks like data exchange, monitoring, and control. DH485 networks typically operate at relatively low speeds compared to modern Ethernet-based protocols.
