GRUNDFOS COMMUNICATION INTERFACES
The CIM/CIU 200 is a standard interface for data transmission between a Modbus RTU network and a
Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and
a PLC or SCADA system.
Extensive amounts of datapoints are available from each product via the CIM/CIU 200. The interface
offers uncomplicated system integration with both new and legacy systems, as the Modbus RTU
protocol is widely supported by existing control systems and PLCs.
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 Modbus, interface modules are also available for GENIbus, BACnet, Profibus, LON, GSM
and other systems.
Communication interface for Modbus
– for automation
CIM 200 add-on module
The CIM 200 is an add-on communication module
installed internally in 11-22 kW Grundfos E-pumps or
Dedicated Controls.
CIU 200 wall-mounted/DIN-rail unit
The CIU 200 with internal power supply is for Grund-
fos products that do not support the add-on module.
