Grundfos CIU 501 User Manual

12.1.3 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.
• Setting a SCADA PIN code:
SETSCADACODE <access code>
Will enable write access protection. Default is an empty SCADA PIN code, meaning no protection.
• Activating the SCADA PIN code:
SCADACODE <ON | OFF>.
Default is "Off".
• Selecting the Modbus address:
MODBUSADDR <1-247>
Default value is 231.
To verify the SCADA settings after completion, use the SMS command "SCADA".
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 value is "Normal".
• Select Connection type:
CONNECTION <SERVER | CLIENT | DISABLE>
Default value is "Server".
• Set data roaming:
DATAROAMING: <ON | OFF>
Default value is "Off".
• Select Modbus TCP port number:
MODBUSPORT <port no.>
Default value is 502.
• Select GENIpro port number:
GENIPROPORT <port no.>
Default value is 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>, <GENIproport>, <username>, <password>, <authentication>, <connection>, <data roaming>,
<data silence timeout>
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.
12.1.4
Operation
When powering on CIU 260 with the correct APN setting, the following APN connection sequence will take place:
1. CIU 260 locates the APN service. The connection state changes from "Detached" to "Attached".
2. CIU 260 attempts to connect to the APN it has been given and requests an IP address. The base station looks through its record of legal
SIM cards and finds the IP address, the address associated with this SIM card, to assign to CIU 260. After CIU 260 has got the IP address,
the connection state changes to "Context active".
