3.1 Security
Grundfos connected products must be behind a
firewall or connected to a private network.
If a firewall or private network is not in place, the
Grundfos product may be subject to a cyber-security
risk and becomes vulnerable to an attack or
compromise.
Follow the highly recommended configuration
requirements below. If in doubt, consult an IT
Infrastructure Specialist.
3.1.1 CIM 500
CIM 500 is a traditional network-connected device
and must be placed on a private network behind a
firewall. It must not be connected directly to the
Internet. Also, no TCP/IP ports must be forwarded to
the product. If you need remote access to the device,
you must use technologies such as Virtual Private
Networks (VPNs) to ensure a secured connection.
Consider contacting an IT Infrastructure Specialist to
establish such a solution.
For CIM 500 in mode 4, GRM IP (Grundfos Remote
Management) the firewall must accept connections
initialised by the Grundfos product to the Internet
only (outgoing connections).

3.2 Connecting the Ethernet cable
Use RJ45 plugs and an Ethernet cable. Connect the
cable screen to protective earth at both ends.
Maximum cable length
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
and CIM 500 has a built-in switch which means that
the cable can run another 100 metres whenever
passing a CIM 500 module.
Fig. 4 Example of Industrial Ethernet network
Fig. 5 Example of Ethernet connection
It is important to connect the cable screen
to protective earth by means of the earth
clamp or in the connector.
For GRM IP communication, ensure that
the network is protected by a firewall.

Webserver configuration
The built-in webserver offers easy monitoring of the CIM 500 module and makes it possible to configure the
selected Industrial Ethernet protocol. Using the webserver, you can also update the firmware of the CIM 500
module and store or restore settings, among other functions.
To connect a PC to 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 subnetwork as CIM 500, for example 192.168.1.101.
See section How to configure an IP address on your PC using Windows 7 or How to configure an IP
address on your PC using Windows 10.
3. Open a standard Internet browser and type 192.168.1.100 in the URL field.
How to configure an IP address on your PC using Windows 7
1. Open "Control Panel".
2. Select "Network and Sharing Center".
3. Click [Change adapter settings].
4. Right-click and select "Properties" for the Ethernet adapter. Typically "Local Area Connection".
5. Select properties for "Internet Protocol Version 4 (TCP/IPv4)".
6. Select the "Alternate Configuration" tab and enter the user-configured IP address and the subnet mask you
would like to assign to your PC. See fig. 1.
Fig. 1 Example from Windows 7
How to configure an IP address on your PC using Windows 10
1. Search for "Ethernet" in Windows.
2. Select "Change Ethernet setting".
3. Select "Change adapter options".
4. Right-click "Ethernet" and select "Properties".
5. Select properties for "Internet Protocol Version 4 (TCP/IPv4)".
6. Select the "Alternate Configuration" tab and enter the user-configured
IP address and subnet mask you would like to assign to your PC.

Login
For administration of username and password, see also User Management.
Fig. 2 Login
If you experience problems with logging in
to the webserver after a firmware update,
perform a factory reset.
TM07 4522 1919
Object Description
Username Enter username.
Default: admin.
Password
Enter password. Default: Grundfos.
After the first log in, you are forced to change the password.
The password must contain:
• at least 8 and maximum 20 characters
• at least one lower case letter
• at least one upper case letter
• at least one numeric or special character.
When logging in, you have four attempts before a back-off algorithm starts an
exponentially increasing time delay between each attempt. Power cycling CIM 500
resets the back-off algorithm.

PROFINET IO configuration
This web page is used to configure all the parameters relevant to the PROFINET IO protocol standard.
Fig. 3 RealTime Ethernet Protocol Configuration - PROFINET IO
TM07 4525 1919
Object Description
Device Name
Fill in a device name according to the PROFINET rules:
• It consists of one or more labels separated by a dot.
• The total length is 1 to 240 characters.
• The length of a label is 1 to 63 characters.
• Labels only consist of lower case characters, digits and "-".
The first and the last character of a label must not be "-".
IP Address This field is read only. The IP address is assigned from the PLC. PROFINET IO is not
allowed to share the IP address with a CIM 500 webserver.
Subnet Mask This field is read only. The subnet mask is assigned from the PLC.
Gateway This field is read only. The gateway address is assigned from the PLC.
Grundfos product
simulation
The module can be put in product simulation mode to generate realistic simulated
values of all the PROFINET IO input data. It will thus be possible to connect a
PROFINET IO master to a module fitted in a CIU or an E-box without installing this
device in a real industrial process system. In an office environment, it can then be
verified that communication works, and data is received and handled correctly by the
PROFINET IO master application program (for example PLC program) before installing
the device.
To enable product simulation, select a product type from the dropdown list.
To terminate product simulation, select "No Simulation".
Restart Press the restart button if the LED1 flashes red, which indicates a wrong or missing
PROFINET IO configuration.

Modbus TCP configuration
This web page is used to configure all the parameters relevant to the Modbus TCP protocol standard.
Fig. 4 Real Time Ethernet Protocol Configuration - Modbus TCP
TM07 4523 1919
Object Description
TCP Port Number
The default value is 502, the official IANA-assigned Modbus TCP port number.
The number 502 is always active implicitly.
If you select another value in the webserver configuration field, both the new value and
value 502 will be active.
IP Address Configuration of the static IP address if a DHCP server is not used. Modbus TCP is not
allowed to share the IP address with a CIM 500 webserver.
Subnet Mask Configuration of the subnet mask if a DHCP server is not used.
Gateway Configuration of the gateway address if a DHCP server is not used.
Use DHCP
The module can be configured to automatically obtain its Modbus TCP network settings
from a DHCP server if available on the network.
Default: DHCP disabled. "Use DHCP" is unchecked.
