• The second category of the channels describes includes all connections to the
gateway which can be set up from your local PC, over this configuration dialog for
example. They create the "branch" which leads from the minus sign directly below
to PC_PLC1 and PC_PLC4. These channel addresses do not necessarily have to be
known yet at the gateway. For PC_PLC4 in the example described above, the
configuration parameters are stored locally in the project but they will first be
known to the gateway the next time log-in to the run-time system occurs. This has
already occurred for PC_PLC1 since the associated gateway address has appeared
as an additional "sub-branch" to the "channel tree".
In the central part of the dialog one finds the designation, in each case, of the left
selected channel and the associated parameter under Name, Value and Comment.
6.6.27 Tips for editing the parameters in the communications parameters dialogue
You can only edit the text fields in the column Value.
Select a text field with the mouse, and get into the editing mode by double clicking or
by pressing the space bar. The text input is finished by pressing the key.
You can use or + to jump to the next or the previous
switching or editing possibility.
To edit numerical values it is possible with the arrow keys or the Page Up/Down keys
to change the value by one or ten units respectively. A double click with the mouse
also changes the value by increasing by one unit. A typing check is installed for
numerical values: + or + deliver the lowest or the highest
value respectively for the possible input values for the type of parameter in question.
6.6.28 Quick check in the event of unsuccessful connection attempt to the gateway
You should make the following checks if the connection to the selected gateway
computer is not successful. (You get the message „not connected" in the
Communication Parameters dialog behind the gateway server address in the field
Channels):
• Has the gateway server been started (the three-color symbol appears in the
bottom right portion of the toolbar) ?
• Is the IP address that you entered in the 'Gateway: Communication Parameters'
dialog really that of the computer on which the gateway is running ? (use „ping" to
check)
• Is the TCP/IP connection working locally? The error may possibly lie with TCP/IP.
