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.
