2.3 Connection via Network (LAN / Ethernet)
The CO3000 can be operated in a normal TCP/IP network. It has no website. It is not possible to run it
via an internet browser!
2.3.1 Connection
The controller can be connected to a PC or switch by using a normal network cable (not crossover!) in
the network socket in the back of the CO3000.
2.3.2 Settings
DHCP mode (Preset) Static mode (Example)
Hostname CO3000 CO3000
IP address Automatic 192.168.0.42
Network mask Automatic 255.255.255.0
Gateway Automatic 192.168.0.1
Port 5025 5025
The CO3000 is delivered with the DHCP activated. If a static address is desired, this can be set on the
CO3000.
In its original setting, the hostname “CO3000” is preset. If you are operating several controllers on the
same subnet, the hostnames must be unique. Depending on the DHCP server you are using on the
network, various negative effects can occur on the network if several network-capable devices use the
same hostname. The hostname can be changed in the CO3000 settings.
The settings for the gateway are irrelevant in most cases, because the CO3000 does not make an
Internet connection.
2.3.3 Communication
No additional protocols such as HTTP are used. Sockets can be used for communication. The
commands can be written directly to the previously opened socket and the return values read from it.
When communicating via LAN, please note that unlike GPIB it is not possible to read a return value
from the CO3000 several times. A return value can only be read if a command has been sent to the
CO3000.
After receiving and decoding the command, the CO3000 will immediately send the return value to the
invoker. Depending on the network, it may take some time to receive the return value (> 100ms).
