1 Overview
This additional module enables the acquisition and storage of large amounts of data
(such as measuring and balance values of the solar system) over a long period of
time. System access is possible with just a few clicks via the VBus.net Internet portal.
For transmission of the data stored in the internal memory of the DL2 to a PC, an
SD card can be used.
The DL2 is appropriate for all controllers with RESOL VBus®.The datalogger can be
connected directly to a PC or router for remote enquiry and thus enables comfor-
table system monitoring for yield monitoring or for diagnostics of faults.

7.2 Accessing the DL2 Datalogger over the Internet withoutVBus.net
The DeviceDiscoveryTool cannot be used for nding a DL2 Datalogger over
the Internet.
The following preparations have to be made when a DL2 Datalogger connected to
the Internet via a router is to be accessed over the Internet:
ÎAssign a static address to the router.
ÎCarry out port routing in the router.
Assigning a static router address
In order to access the router and the DL2 connected over the Internet, a static
address has to be assigned to the router.
There are 2 different ways to assign a static Internet address to the router:
• Over a dynamic Domain Name Server (DynDNS)
• Over a static Internet IP address

Not all routers support DynDNS services. For further information consult
the router documentation.
It is possible to reserve an Internet address via a DynDNS service provider. Dy-
nDNS services are usually free of charge.
Schematic process representation of using a DynDNS address:
1. Open an account for a DynDNS Internet address at a DynDNS service provid-
er.A DynDNS Internet address and the corresponding access information will
be provided.
2. The DynDNS access information has to be entered into the router, so that the
router can tell the DynDNS service provider where to route enquiries to.
3. In order to access the router via the Internet, the user has to enter the Dy-
nDNS Internet address into the Internet browser.

It is possible to apply for a static Internet IP address at an Internet Service Provider
(ISP). For a static IP address, there usually is a fee required.
Schematic process representation of using a static IP address:
1. Apply for a static IP address at an Internet Service Provider (ISP). A static Inter-
net address and the corresponding access information will be provided.
2. The access information has to be entered into the router, so that the router
can register at the ISP with the static IP address.
3. The router registers at the ISP with the static IP address.
4. In order to access the router via the Internet, the user has to enter the static
Internet address into the Internet browser.
Port routing in the router
Not all routers support port routing. For futher information consult the
router documentation.
In order to access, over the Internet, one or several Dataloggers connected to one
router, port routing has to be congured in the router.
The DL2 Datalogger communicates via the following ports:
• Web interface port: 443 (adjustable, default port: 443)
• RESOL ServiceCenter port: 7053 (non-adjustable)
In order to carry out port routing in the router, proceed as follows:
ÎAssign a static LAN IP address to the DL2 Datalogger using the conguration
menu of the router.
ÎAssign a port to the IP address menu using the conguration menu of the
router.
In this example (see table below), 3 DL2 Dataloggers are assigned 1 Web interface
port and 1 RESOL ServiceCenter software port each.
See chap. 7.4 Log mode conguration, page 17.
The Log interval determines the interval in which the DL2 Datalogger logs data.
Log intervals between 1 second and 86400 seconds (24 hours) are possible.
The smaller the log interval, the more memory capacity is used.

7.4 Logmodeconguration
The Log mode determines how the DL2 Datalogger behaves when its internal
memory capacity is fully used.
There are 2 different settings possible for the log mode conguration:
• Cyclic logging (factory setting): When the memory capacity is fully used, the old-
est data are overwritten.
• Linear logging: When the memory capacity is fully used, data logging stops.
In order to congure the log mode, proceed as follows:
ÎIn the main menu DeviceCong, select the sub-menu General.
ÎOn the Logging Conguration tab, in the Log mode dropdown menu,
select the desired value.

7.5 Networkconguration
The network conguration determines where the DL2 Datalogger obtains its IP
information.
There are 2 different settings possible for the network conguration:
• Dynamic (DHCP): The IP information is automatically assigned to the DL2
Datalogger by the DHCP server.
• Static: The user manually assigns date and time information to the DL2 Datalogger.
Consult the system administrator before changing the factory settings!
In order to congure the network conguration, proceed as follows:
ÎIn the main menu DeviceCong, select the sub-menu Network.
ÎIn the LANcongurationmodedropdown menu, select the desired value.
ÎClick Saveconguration.
The message Congurationsavedsuccessfully! appears.
The menu item IP Recovery can be used to automatically retrieve a new IP ad-
dress for the DL2 in the case that the previous one is lost. In order to congure the
automatic IP address conguration, proceed as follows:
ÎIn the IP Recovery menu item, select Ye s .
ÎClick Saveconguration.
The message Congurationsavedsuccessfully! appears.

7.6 Datadisplayconguration
Example of a live data display
The DL2 Datalogger displays live data of the controller connected. In the tabular
overview, the data are refreshed automatically every 10 seconds.
The data can be displayed as follows:
• In a schematic drawing of the system in which sensor data are assigned to the
components.
• In a tabular overview (factory setting).
In order to reduce the data trafc from the local network to the Internet, the
background drawing of the system can optionally be stored on an Internet server.

Requirements for the display of live data in a schematic drawing of the
system
The following requirements must be met in order to display live data (of a control-
ler connected) in a schematic drawing of the system:
• A schematic drawing of the system must be created using a drawing program (e.
g. Inkscape or Graphic Works).
• The schematic drawing must be supplied in one of the following formats: *.jpg,
*.gif, *.png, *.bmp, *.tif.

8 Firmware update with SD card
New rmware versions extend the functional range and enhance the operation.
The current software can be downloaded from www.resol.de/rmware.
In order to run a rmware update over the SD memory card slot, proceed as
follows:
ÎDownload the rmware from the Internet (www.resol.de/rmware) and save
it to your PC.
ÎExtract the le.
Among the extracted les there is a folder called SDCARD.
ÎInsert an SD card formatted with the FAT32 format into the PC.
ÎCopy the contents of the SDCARD folder onto the rst level of the SD card.
There should then be a folder structure called RESOL/DL2 on the SD card, con-
taining the rmware le.
ÎRemove the SD card from the PC and insert it into the SD card slot of the DL2.
The rmware update is being run and the DL2 automatically reboots. This may take
a few minutes. The operating control LED starts ashing, lights up for a while and
then all LEDs go out.
ÎWait until the operating control LED is permanently green.
