Fieldbus Controller 750-841 • 79
Starting up an ETHERNET TCP/IP fieldbus node
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
3.1.6.2 Connecting PC and Fieldbus Node
Connect the assembled ETHERNET TCP/IP fieldbus node to a hub using a
standard Ethernet cable, or directly to the PC with a “crossover” cable. The
transmission rate of the controller is dependant on the baud rate of the PC
network interface card.
Attention
For a direct connection to a PC, a “crossover” cable is required instead of a
parallel cable.
Now start the BootP server on the PC and apply power to the controller (DC
24 V power pack). Once the operating voltage has been switched on, the PFC
initialization starts. The fieldbus controller determines the configuration of the
I/O modules and creates the process image. During the startup the 'I/O' LED
(Red) flashes at a high frequency.
When the I/O LED turns green, the fieldbus controller is ready for operation.
If an error has occurred during startup, a fault code is flashed on the 'I/O'-LED.
If the I/O LED flashes 6 times (indicating error code 6) and then 4 times
(indicating error argument 4), an IP address has not been assigned yet.
3.1.6.3 Determining IP Addresses
If your PC is already connected to an ETHERNET network, it is very easy to
determine the IP address of your PC. To do this, proceed as follows:
1. Go to the Start menu on your screen, then go to the menu item Settings/Control
Panel and click on Control Panel.
2. Double click the icon Network
The network dialog window will open.
3. - Under Windows NT: Select the tab: Protocols and highlight
the listbox item TCP/IP protocol.
- Under Windows 9x: Select the tab: Configuration and highlight
the listbox item TCP/IP network card.“.
Attention
If the entry is missing, please install the respective TCP/IP component and restart
your PC. The Windows-NT installation CD, or the installations CD for Windows
9x is required for the installation.
4. Then, click the Properties button. The IP address and the subnet mask are
found in the IP address tab. If applicable, the gateway address of your PC is
found in the Gateway tab.
5. Please write down the values:
IP address PC: ----- . ----- . ----- . -----
Subnet mask: ----- . ----- . ----- . -----
Gateway: ----- . ----- . ----- . -----
