3.3. Defining I/O Boards
The Edit menu contains the commands to define the selected board (setup its parameters) and to
connect I/O variables to its channels.
3.3.1. Selecting I/O board type
Before connecting I/O variables to a board, the board identification must be entered. A library of pre-
defined boards is available on the IEC1131 TOOLSET workbench. This library may have been
compiled by one or more I/O device suppliers. The Edit/Set Board/Equipment command is used to
setup board identification. This command can be used to select either a single board or complex I/O
equipment, from the IEC1131 TOOLSET library. It is also possible to double click on a slot to set the
corresponding board or equipment.
All the channels of a single board have the same type (boolean, integer/real or message) and direction
(input or output). Real and integer variables are not distinguished during I/O connection. A complex
I/O equipment represents an I/O device with channels of different types or directions. A complex I/O
equipment is represented as a list of single I/O boards. It uses only one slot in the rack list.
3.3.2. Technical notes
The Edit/Technical note command displays the on-line user's guide of the selected board or complex
equipment. The technical note and associated product description contain all the information required
to enable the user to configure the board correctly.
3.3.3. Removing a board
The Edit/Clear slot command is used to remove the currently selected board or I/O equipment. If
variables are already connected to the corresponding channels, they are automatically disconnected
when clearing the slot.
3.3.4. Real boards and virtual boards
The Edit/Real/virtual board command sets the validity of the selected board or complex I/O
equipment. The following icons are displayed in the rack list to show the validity of a board:
……..real I/O board
……..virtual I/O board
In Real Mode, I/O variables are directly linked to the corresponding I/O devices. Input or output
operations in the application program tie directly to corresponding input or output conditions of the
actual field I/O devices. In Virtual Mode, I/O variables are processed exactly as internal variables.
They can be read or updated by the debugger, so that the user can simulate the I/O processing, but no
real world connection is made.
