Grundfos (www.grundfos.com) announced that it has developed a new Communication Interface Unit (CIU) and Communication Interface Module (CIM) which facilitates the connection of Grundfos’ products to standard fieldbus networks.

Interoperable and open data bus networks are becoming a significant part of monitoring pump systems. The company said the new products offer better integration of field devices and data communication.

The CIU and CIM help enable data communication through interoperable and open networks like LONWorks, Modbus RTU, Profibus DP, the Grundfos Remote Management system (GRM) and BACnet MS/TP wireless through GSM/GPRS.

Based on the standard functional profiles, the new modular concept is applicable for future needs. The open communication standards offer secure and flexible communication solutions that help protect and optimize investment, as a variety of pumps can be connected into the supervisory system.

The CIU and CIM communication interfaces are easy to commission and install. Meanwhile, the CIM model allows communication with E-pumps ranging from 11 kW to 22 kW, including the new Dedicated Controls for wastewater pumps. CIU wall-mounted models are also available to replace Grundfos products that do not feature and support the CIM add-on module, such as the smaller boosters and e-pumps.

Additionally, both modules feature integrated LEDs that help in the commissioning face as well as indicate the status of the connected communication network. Both models also enable the incorporation of pumps and pump systems into the PLCs, SCADA systems and other monitoring and controlling systems.
