Status lamps

In the bottom part of the left pane, two lamps are visible, indicating the

status of the TCP/IP connection. The left lamp indicates the status

of the connection between the IO module and the eKERNEL. The

right lamp indicates the TCP/IP status between the IO module and

the external device (if applicable). Both are green in Figure 58 "Status

lamps" (page 172). There are three possible colors for these lamps:

— Green

TCP/IP connection (socket) is opened without errors.

— Red

Indicating an error in trying to open the socket (TCP/IP connection).

— Black

Not applicable, because there is no TCP/IP connection specified.

To find out which TCP/IP ports are in use by Windows services, you can

display the contents of the services file using an ASCII editor. You can find

the services file in the following directory:

c:\WINNT\system32\drivers\etc\services

Note: The file does not have a file extension.
