The Grundfos Communication Interface Module (CIM) and the Communication Interface Unit (CIU) enable the connection of Grundfos products to standard fieldbus networks. The CIM/CIU communication interfaces 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). The series of Grundfos CIM/CIU Communication interfaces 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 optimize and protect investments, all the way to the pump field. The modular design is prepared for future needs and is based on standard functional profiles. Grundfos CIM/CIU communication interfaces are easy to install and commission. CIM modules are add-on modules that allow communication with 11 to 22 kW E-pumps, including the new Dedicated Controls for wastewater pumps.
