3. System description
3.1 Modbus
The system diagrams provide an overview of the different
technologies and how to connect the module or unit to the Grundfos
E pump that you connect to a Modbus network.
CIM solution
The Communication Interface Module (CIM) is an add-on
communication module you install internally in a Grundfos
E-pump using a 10-pin connection. In this setup, the E-pump will
supply power to CIM 200.
For mounting of the CIM add-on module, see the installation and
operating instructions for the E-pump in question.
CIU solution
The Communication Interface Unit (CIU) is a box with a power
supply module and a CIM Modbus module. You can mount either on
a DIN rail or on a wall.
You use it in conjunction with Grundfos E-pumps that do not support
an internal, add-on communication module, CIM.
