2. Applications
The CIM 500 Ethernet module enables data
transmission between an industrial Ethernet network
and a Grundfos product.
The module supports various industrial Ethernet
protocols. See section 3.2 Selection of industrial
Ethernet protocol.
The module is fitted in the product to be
communicated with or in a CIU 500.
Retrofitting of the module is described in the
installation and operating instructions of the
Grundfos product.
Configuration is done via the built-in web server,
using a standard web browser on a PC.
See the specific functional profile on the DVD
supplied with the Grundfos product.

3. Installation
3.1 Connecting the Ethernet cable
RJ45 plugs and Ethernet cable must be used.
The cable screen must be connected to protective
earth at both ends.
Maximum cable length
Cable type
The CIM 500 is designed for flexible network
installation. The built-in two-port switch makes it
possible to daisy chain from product to product
without the need of additional Ethernet switches.
The last product in the chain is only connected to
one of the Ethernet ports. Each Ethernet port has its
own MAC address.
Fig. 2 Example of industrial Ethernet network
Fig. 3 Example of Ethernet connection
Warning
The CIM 500 must only be connected to
SELV or SELV-E circuits.

It is important to connect the cable
screen to earth by means of the earth
clamp or in the connector.

3.2 Selection of industrial Ethernet
protocol
The module has a rotary switch for selection of the
industrial Ethernet protocol. See fig. 4.

3.3 Setting up the IP addresses
The module comes with fixed IP address. The IP
address settings can be changed with the built-in
web server.
3.4 Connection to the web server
The module can be configured by means of the
built-in web server. To establish a connection from a
PC to the CIM 500, proceed as follows:
1. Connect the PC and the module, using an
Ethernet cable.
2. Configure the Ethernet port of the PC to the
same network as the CIM 500, e.g.
192.168.1.101, and the subnet mask to
255.255.255.0.
See section How to configure an IP address on
your PC on page 10.
3. Open a standard Internet browser and type
192.168.1.100 in the URL field.
4. Log in to the web server:
