ETHERNET TCP/IP
3.1.6.2 Connecting PC and fieldbus node
Connect the assembled ETHERNET TCP/IP fieldbus node via a hub or
directly to the PC using a 10Base-T cable. The transmission rate of the coupler
is dependant on the baud rate of the PC network interface card..
Attention
For a direct connection, a crossover cable is required instead of a parallel cable.
Now start the BootP server on the PC and apply power to the coupler
(DC 24 V power pack). Once the operating voltage has been switched on, the
fieldbus coupler initialization starts. The fieldbus coupler 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 coupler is ready for operation.
If an error has occurred during startup, a fault code is flashed on the 'I/O' LED
(red).
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, menu item
Settings
and click on
Control Panel.
2. Double click the icon
Network
.
The network dialog window will open.
3. - Under Windows NT: Select the register:
Protocols
and mark
the entry
TCP/IP protocol.
- Under Windows 9x
:
Select the register:
Configuration
and mark
the entry
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. Subsequently, click the button "Properties...".
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:
