Introduction; About This Functional Profile; Assumptions; Definitions And Abbreviations - Grundfos CIM 200 Functional Profile And User Manual

2. Introduction

2.1 About this functional profile

This functional profile describes the following modules and units:
• CIM 200 Modbus RTU
• CIM 260 3G/4G cellular
• CIM 500 Ethernet for Modbus TCP
This functional profile applies to the following Grundfos products:
• Grundfos level-control system LC 2X1 for wastewater
applications
• Grundfos level-control system LC 2X2 for water supply
applications.
Grundfos cannot be held responsible for any problems caused
directly or indirectly by using information in this functional profile.

2.2 Assumptions

This functional profile assumes that the reader is familiar with the
commissioning and programming of Modbus devices. The reader
should also have some basic knowledge of the Modbus protocol
and technical specifications.
It is also assumed that an existing Modbus network with a
Modbus master is present.
