    The motors incorporate a functional module. The functional module is available in various versions with different inputs and outputs. You can fit the motors with a Grundfos add-on communication interface module (CIM). The module enables data transmission between the motor and an external system, for example a BMS or SCADA system. The module communicates via fieldbus protocols.
