2. Introduction
2.1 About this functional profile
This functional profile describes the following modules and units:
•
CIU 202 Modbus RTU
•
CIU 262 Modbus 3G/4G cellular
•
CIU 502 Modbus ethernet for Modbus TCP
You cannot order CIU 502 separately.
Order a CIU 902 box unit and a CIM 500 module to
install in the CIU 902 box.
This functional profile applies to the following Grundfos products:
•
DP, EF, SL1, SLV and SEG AUTO
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.
