3.5. Connecting I/O Channels
When a board is defined, the user has to connect I/O variables to its channels. The following icons are
used to represent channels in the list:
.…..free channel
.…..connected channel
3.5.1.
Connecting variables
To set the connection of a channel, double click on its location in the list on the right. It is also possible
to select (highlight) it and run the Edit/Set channel/parameter command.
The dialogue box shown in Figure 44 below appears.
Figure 44 Connect I/O Channel Dialogue Box
The list contains all the variables which match the selected board type and direction. Only variables
which are not yet connected are listed here. The Connect button connects the variable selected in the
list to the selected channel. The Free button removes (disconnects) the variable from the selected
channel. Next and Previous buttons are used to select another channel of the board. The location of
the selected channel is always displayed in the title of the dialogue box.
3.5.2.
Removing connected variables
The Tools/Free board channels command disconnects all the I/O variables already connected on the
selected board.
3.5.3.
Comments
The comment text of a declared I/O variable is displayed with its name in the board list. As IEC1131
TOOLSET also enables the use of directly represented variables (% notation), comments may also be
attached to free channels. Use the Tools/Set channel comment command to enter a comment for
the free channel currently selected in the board list. This command cannot be used to change the
comment of an I/O variable declared in the project dictionary. However, these comments appear in the
program editors in the Select Variable dialogue, against the appropriate directly represented variable.
