3. System description

3.1 Modbus

Grundfos level control LC 2X1 is connected to one or two
Grundfos wastewater pumps. Grundfos level control LC 2X2 is
connected to one or two Grundfos submersible pumps for water
supply. The controllers offer status information as well as control
and monitoring of a wastewater system via an operating panel.

3.2 CIM 200 Modbus RTU

CIM 200 is an add-on communication module that you fit in the
LC 2X1/LC 2X2 controller using a 10-pin connection. This
enables communication with, for example, a PLC or SCADA
system.
Via the Modbus RTU connection, it is possible to control the
system and for example read status, measured values and logs.

3.3 CIM 260 3G/4G cellular

CIM 260 is an add-on communication module that you fit in the
LC 2X1/LC 2X2 controller using a 10-pin connection. This
enables cellular communication with, for example, a PLC, SCADA
system and mobile phones.
Via the cellular network connection, it is possible to control the
system and for example read status, measured values and logs
using the modbus protocol.
