BACnet is a data communication protocol for Building Automation and Control Networks. It is a standardised technology for building automation and supports a variety of specific physical network standards, which makes it ideal for use on all automation levels.
A fieldbus is the information highway that connects the components in a BMS system to allow monitoring and controlling of air-conditioning systems, heating systems, lighting systems, ventilation, wastewater systems etc.
GENIbus is an open data communication protocol developed and maintained by Grundfos. It is used to connect Grundfos pumps to pump controllers or via gateways to monitoring and supervisory computers in Building Management Systems and SCADA systems.
Grundfos CIM/CIU Communication Interfaces
The CIM/CIU products provide standard interfaces for data transmission between Grundfos pumps and various communication technologies.
Grundfos CU351 - Control unit
CU 351 is a flexible control unit for controlling and monitoring of up to six identical pumps + a pilot pump. CU 351 serves as the controller for Grundfos Hydro MPC booster sets and Control MPC systems.
LON is an open network technology which is mainly used in building automation. The name LON is short for "Local Operating Network".
It is an event-based technology that supports a variety of physical network standards, making it ideal for use on all automation levels.
Modbus is an open network technology used in building management systems and across a wide range of industries. It is a de facto standard for data communication, which makes it ideal for use on all automation levels.
