GRUNDFOS COMMUNICATION INTERFACES
The CIM/CIU 300 is a standard interface for data transmission between a BACnet MS/TP
network and a Grundfos pump. It makes data exchange possible between pumps and a
SCADA system or supervisory controller.
The communication interface is based on standard BACnet object types, allowing for straight
forward data access over the network.
The BACnet functional profile has been optimised for exchanging data between pumping
systems and building management systems / operator workstations.
The interface module can be
installed as an internal add-on or as a wall-mounted unit where
internal connection is not supported. The wall-mounted unit is equipped with a 24-240 VAC/
VDC power supply.
In addition to BACnet, interface modules are also available for GENIbus, LON, Modbus,
Profibus, GSM and other systems.
Communication interface for BACnet MS/TP
- for building automation
CIM 300 add-on module
The CIM 300 is an add-on communication module
installed internally in 11-22 kW Grundfos E-pumps.
CIU 300 wall-mounted/DIN-rail unit
The CIU 300 with internal power supply is for
Grundfos products that do not support the add-on
module.
