Grundfos CIM/CIU Communication Interfaces Possibility in every drop
Open the catalog to page 1CIM & CIU communication interfaces Fieldbus communication Why CIM/CIU connectivity interfaces? • Pumps and controllers have better reliability with reduced downtime, due to monitoring and control functionality on a PLC, BMS/SCADA system • The operational cost of pumps can be lowered by reducing setpoints to match precise system needs via remote control • Remote monitoring and control via PLC, BMS/ SCADA systems reduce manual settings, monitoring time and travel time to sites or installations • Enable predictive maintenance and fast reaction time on process changes and exceptions • One solution...
Open the catalog to page 2Fieldbus Communication Note: To create a CIU xxx solution, you need to order a CIU 900 + the required CIM xxx interface and mount the CIM xxx interface into CIU 900. Note: E-pumps are CRE/CRNE/CRIE, MTRE, CME, TPE2/TPE3, NBE/NKE. Note: For TPED and Multi-E a second CIM module can optionally be mounted in pump no. 2 for network redundancy. A second CIM module can optionally be mounted in pump no. 2 for redundancy MAGNA3-D model D requires 1x CIM in master head, MAGNA3-D models A-C require a CIM in each head (for LONWorks 2x CIM 100) CIM 290-MA LPWAN GIC requires an external 4G/3G antenna. Always...

Open the catalog to page 5Fieldbus communication Protocols mainly used at dosing applications Product numbers Modbus RTU, PROFIBUS DP, PROFINET IO, Modbus TCP and EtherNet/IP — For digital dosing pumps The small DDA is mounted directly on top of the E-Box, and the bus cable included with the E-Box is connected between the small DDA and E-Box. The small DDA can also use the CIU unit and in that case the GENIbus cable is ordered separately. The DDA XL always uses the CIU unit solution, the DDA-C has embedded Modbus and uses a CIU unit for other protocols, or requires a special 24V T-Splitter adapter for power supply in...
