12.2.2 Subscription
You have to select the service provider and the technical solution that best suits your system, and it must be based on static IP
addressing. You will get the following from the service provider:
• A Subscriber Identity Module (SIM card).
• An Access Point Name (APN), for example "Internet".
• A fixed user name that cannot be changed by the user.
• A fixed password that cannot be changed by the user.
• A static IP address.
Solutions based on a VPN, Virtual Private Network, involve the use of special routers, for example GRE, Generic Routing Encapsulation,
routers, which you also get from the service provider.

12.2.3 Installation
To prepare CIU 260 for data communication, some settings have
to be made via SMS commands:
• Select Access Point Name:
APN <ASCII string>
This is always mandatory.
• Select Username:
USERNAME <ASCII string>
The need for a user name depends on your operator and the
type of subscription.
• Select Password:
PASSWORD <ASCII string>
The need for a password depends on your operator and the
type of subscription.
Some advanced APN-related settings have default values that
usually work, but in special cases it might be necessary to
change some of them. This is also done via SMS commands.
• Select Authentication:
AUTHENTICATION <NORMAL | SECURE>
Only used by some service providers.
Default setting: NORMAL.
• Select Connection type:
CONNECTION <SERVER | CLIENT | DISABLE>
Default setting: SERVER.
• Set data roaming:
DATAROAMING: <ON | OFF>
Default setting: OFF.
• Select Modbus TCP port number:
MODBUSPORT <port number>
Default setting: 502.
• Select GENIpro port number:
GENIPROPORT <port number>
Default setting: 49152. This is only relevant when using
Grundfos PC Tools.
It is possible to configure the APN connection with a single multi-
parameter command:
• SETAPN <parameter 1, parameter 2, parameter 3, …>
– <parameters>:<APN>,<Modbus port>,<GENIpro port>,
<username>,<password>,<authentication>,<connection>,
<data roaming>, <data silence time out>.
Example
SETAPN
Grundfos.dk2.tdc,502,49888,Grundfos,4321,normal,server,off, 60
To verify the APN settings after completion, use the SMS
command "APNSETTINGS". The command "APNSTATUS" can
verify if the APN connection is working.
The connection states have the following meaning:
– "Detached": Trying to locate APN connection service.
– "Attached": APN connection service located.
– "Context active": IP address has been assigned, ready for a
client to establish a socket connection.
– "Connected": A client has established a socket connection.
The system is ready for TCP/IP data exchange, or already
exchanging data.
For details about the use of SMS commands, see "CIM 260 SMS
commands", which you can download from Grundfos Product
Center.
