Open and interoperable data bus networks are becoming increasingly important for monitoring pumps systems, and the new products offer an improved integration of data communication and field devices, the company says. The CIU and CIM enable data communication via open and interoperable networks such as Profibus DP, Modbus RTU, LONWorks, BACnet MS/TP wireless via GSM/GPRS or to the Grundfos Remote Management system (GRM).
This means a great variety of pumps can be connected to a supervisory system. These open communication standards offer vendor neutral, flexible and secure communication solutions that optimise and protect investments.
The modular design is prepared for future needs and is based on standard functional profiles. Grundfos says that the CIM/CIU communication interfaces are easy to install and commission. The CIMs are add-on modules that allow communication with 11 to 22 kW E-pumps, including the new Dedicated Controls for wastewater pumps. For Grundfos products that do not support the CIM add-on module, such as smaller e-pumps and boosters, CIU wall-mounted or DIN-rail units are available.
The modules feature integrated LEDs which indicate the status of the connected communication network and assist in the commissioning phase. The CIU range has an integrated wide-range power supply from 24 V to 240 V.
The Grundfos CIM/CIU interfaces enable the integration of pumps and pump systems into SCADA systems, PLCs, or other controller or monitoring systems.
