Abstract Sensors, actuators, and controllers communicate with each other in our Water Management Cyber Physical System (WM-CPS). This WM-CPS is also Internet of Things (IoTs) enable because controllers used in WM-CPS always get a unique IP address during connection with internet. In our work, various communication standards like Ethernet/IP, Modbus/TCP, Modbus/RTU, Wi-Fi 802.11n/IP, Wi-Fi 802.11n/UDP, and Wi-Fi 802.11n/TCP are taken under consideration. Raspberry Pi-3 (RPi-3) board is a controller. Relay and Pump are actuators. Our system works on two layers. Sensors and actuators communicate with controllers on Layer 0 (L0). Controller communicate with data base management system (DBMS), web Interface and virtual private server (VPS) at Layer 1 (L1). We have design and develop web interface of our system available with http://cps4wm.info domain name. This WM-CPS is scalable and able to integrate many more sensors and actuators. We have surveyed 22 communication standards for our future WM-CPS.
