Section 2 General information
2.1 Safety information
Please read the entire manual carefully before installing the software. Further information
regarding the sc1000 controller is provided in the sc1000 controller manual.
2.2 Overview of product
The sc1000 controller is designed for Internet-based communication with other users.
The Ethernet port (wired connection) or the GSM/GPRS modem (wireless connection)
serves as the communication interface for the sc1000.
The wired connection via the Ethernet port (used to be service port) is established using
a LAN cable. If necessary, the optional sc1000 outdoor Ethernet port kit can be used to
afford additional protection to the Ethernet port when the sc1000 controller is used
outdoors. sc1000 controllers are also frequently installed in areas unsuitable for a wired
Internet/network connection. Mobile communications networks are a viable option for
collecting data and controlling the sc1000 controller remotely. This "M2M" solution
(M2M = machine to machine) integrates the sc1000 controller in a local IT network via a
GPRS mobile communications network.
A VPN tunnel makes sure that communication between the sc1000 controller and the IT
network is secure.
Once the LAN or GPRS connection has been established, no further steps are necessary
on the sc1000 controller.
The sc1000 controller is configured via a computer web browser. It is also possible to
download data logs/upload software updates in this way.
The optional Modbus TCP software module enables the sc1000 controller to be
integrated directly in PLC systems (PLC = programmable logic controller). PLC systems
record data measured by the sc1000 controller and process this data further.

3 Ethernet connection with fixed IP VPN server
The Ethernet connection is the wired connection between a computer and the Ethernet
port on the sc1000 controller. This Ethernet port is a 10 MB/s Ethernet connection located
on the display module.
A direct connection between the computer and the sc1000 controller is established as
follows:
Via basic Ethernet connection
(Figure 3, point 1)
Scope of application: The sc1000 controller is located within the corporate network or
used for testing purposes.
Via Ethernet connection with secure VPN tunnel
(Figure 3, point 2)
Scope of application: The sc1000 controller is outside of the corporate network.
Via Ethernet connection with fixed IP VPN server
(Figure 3, point 3)
Scope of application: The sc1000 controller is accessible via the Internet from any
location with a fixed IP address.

3.4.1 Establish a basic Ethernet connection
Figure 4 Basic Ethernet connection
If the sc1000 controller is located within the corporate network or is used for testing
purposes, a basic Ethernet connection without VPN between the devices is advisable
(Figure 4).
1. Connect the computer to the corporate network using an Ethernet cable. Make sure
the Internet connection is fully functioning. Open various Internet pages to test the
connection.
2. Connect the sc1000 controller to the network by inserting an Ethernet cable into the
RJ45 Ethernet port (Figure 5).

6. Open a web browser on the computer. Enter the IP address of the sc1000 controller
in the address bar (refer to point 3.). The login page for the sc1000 controller is
displayed (Figure 6).
7. Enter the browser password (refer to Figure 6 and Section 3.4.1 on page 13).
Note: A browser password is essential for web browser-based access to the sc1000 controller.
Figure 6 Login page for sc1000 controller
The Ethernet connection between the computer and the sc1000 controller has now been
established.
3.4.2 Establish an Ethernet connection with secure VPN tunnel
Figure 7 Ethernet connection with secure VPN tunnel
If the sc1000 controller is outside of the corporate network, an Ethernet connection with a
VPN tunnel is required (Figure 7). Information on setting up a VPN tunnel is provided in
Section 3.5 on page 15.
14
3.5 Install a VPN tunnel
If the sc1000 controller is outside of the corporate network, a virtual private network
(VPN) must be installed between the computer and the sc1000 controller. The VPN
makes sure that the computer and sc1000 controller can communicate within a secure
channel (tunnel) that is protected from unauthorized access.
Windows 2000 and Windows XP both provide a built-in VPN server. However this only
enables a single connection to be made between an sc1000 controller and the computer
at any one time. For several connections to run simultaneously, a separate stand-alone
VPN server is required.
Depending on the design of the VPN connection, the VPN server is provided by a mobile
network operator/Internet service provider or the IT department. The design must be
planned thoroughly before installation.
3.5.1 Requirements associated with the sc1000 controller
The sc1000 controller requires a specific VPN software package that must be purchased
from the manufacturer. There are several ways to install the VPN software package on
the sc1000 controller:
• Using an SD memory card
• Using a web browser
Installation
• Using Windows Explorer/FTP data transfer
3.5.2 Requirements associated with the computer
The freeware VPN software "OpenVPN" must be installed on the computer (refer to
Section 3.5.4 on page 17).
3.5.3 sc1000 controller: Install the VPN client using an SD memory card
The sc1000 controller display module includes a build-in slot for SD cards. One of the
functions of the SD card is to update the controller software. Further information
regarding the use of SD memory cards is provided in the sc1000 controller manual.
An SD memory card containing the VPN client software tailored to the sc1000 controller
can be purchased from the manufacturer (refer to Section 5 on page 45).
Note: Only use SD cards with a maximum memory size of 1 gigabyte for installation.
1. Create the following directories on the SD memory card (if not yet created):
• DEV_SETTINGS
• SC1000
• UPDATE
2. Copy the following files to the UPDATE directory on the SD memory card:
From manufacturer:
• Tailored VPN client software for sc1000
(if not already installed on the SD card contact the support of the manuafcturer)
