7.3 Setting up the IP addresses

The CIM 500 ethernet module is default set to a fixed IP address.
It is possible to change the IP address settings from the built-in
webserver.
Default IP settings IP address:
used by the Subnet mask: 255.255.255.0

7.4 Establish connection to the webserver

You can configure the CIM 500 module using the built-in
webserver. To establish a connection from a PC to CIM 500, the
following steps are required:
• Connect the PC and the CIM 500 module using an ethernet
cable
• Configure the PC ethernet port to the same subnetwork as
CIM 500, for example 192.168.1.101, and the subnet mask to
255.255.255.0. See section
on page 57.
address on your PC
• Open a standard Internet browser and type 192.168.1.100 in
the URL field.
• Log in to the webserver using the following:
User name
Password
User name and password may have been changed
from their default values.

A.2 Webserver configuration
You can use both ETH1 and ETH2 to establish a
connection to the webserver.
You can access the webserver while the selected
Industrial protocole is active.

7.5 Status LEDs

The CIM 500 ethernet module has two Status LEDs: LED1 and
LED2. See fig. 15.
• Red and green status LED1 for ethernet communication
• Red and green status LED2 for internal communication
between CIM 500 and the Grundfos product.
