Fieldbus controller 750-842
Starting up ETHERNET TCP/IP fieldbus nodes
Modular I/O System
ETHERNET TCP/IP
The examples mentioned above contain the following information:
Declaration
Meaning
node1,
node2
Any name can be given for the node here.
ht=1
Specify the hardware type of the network here.
The hardware type for ETHERNET is 1.
(The numbers are described in RFC1700)
ha=0030DE000100
ha=0030DE000200
Specify the hardware address or the MAC-ID of the ETHERNET
fieldbus controller (hexadecimal).
ip= 10.1.254.100
ip= 10.1.254.200
Enter the IP address of the ETHERNET fieldbus controller (decimal)
here.
T3=0A.01.FE.01
Specify the gateway IP address here.
Write the address in hexadecimal form.
sm=255.255.0.0
In addition enter the Subnet-mask of the subnet (decimal), where the
ETHERNET fieldbus controller belongs to.
No gateway is required for the local network described in this example.
Therefore, the first example: "Example of entry with no gateway" can be
used.
2.
Move the mouse pointer to the text line: "Kein-
Proxy:ht=1:ha=0030DE000100:ip=10.1.254.100" and delete the 12 character
hardware address which is entered after ha=...
Enter the MAC-ID of your own network controller.
3.
If you want to give your fieldbus node a name, delete the name "node1" and
enter any name in its place.
4.
To assign the controller a desired IP address, delete the IP address specified
in the example which is entered after ip=...
Replace it with the IP address you have selected, making sure you are sepa-
rating the 3 digit numbers by a decimal.
5.
Because the second example is not necessary at present, insert a “#” in front
of the text line of the second example: "# hamburg:hat=1:ha=003 0DE 0002
00:ip=10.1.254.200:T3=0A.01.FE.01", so that this line will be ignored.
Note
To address more fieldbus nodes, enter a corresponding text line showing the
corresponding entries for each node. Also note that the # symbol tells the
BootP server to ignore any data after it, for that specific line.
6.
Save the altered settings in this text file "bootptab.txt". To do this go to the
File menu, menu item Save, and close the editor.
