The CIM/CIU 250 is a standard interface for data transmission over a GSM/GPRS network between a Modbus master and a Grundfos pump or controller. It makes remote data exchange possible between Grundfos pumping systems and a PLC or SCADA system. It can be used as an SMS interface to control and monitor a Grundfos product from a mobile phone. It is possible to get a message whenever a warning or an alarm occurs, to request the status or to do simple control like START, STOP and adjusting of setpoint. The interface module can be installed as an internal add-on or as a wall-mounted unit (for products where internal connections are not supported).
