The CIM 200 is a Grundfos communicatio interface module used for communication with a Modbus RTU network
The CIM 200 has terminals for the Modbusconnection. DIP switches are used to select parity and stop vbits, to select transmission speed and to set line
termination. Two hexadecimal rotary switches are used to set the Modbus address. Two LEDs are used to indicate the actual status of the CIM 200 communication. One LED is used for indication of correct connection to the pump, and the other is used to indicate Modbus communication status
