The integrator enabled Modbus TCP on every W3000 controller. They polled registers 30003 (Leaving Water Temp) and 30100 (Comp Amps) into a Niagara 4 BMS. For effective monitoring, focus on these common registers
Modbus is a master-slave protocol that enables communication between electronic control devices. Developed in 1979, it has become a widely accepted standard in various industries, including HVAC, industrial automation, and building management systems. Modbus allows devices from different manufacturers to communicate with each other seamlessly, facilitating data exchange, monitoring, and control. Developed in 1979, it has become a widely
