Abstract
In an industrial controller associated with independent I/O modules for exchanging signals between a controlled machine and the controller, a control program executed by the controller is associated with an I/O map identifying functionality of the independent I/O modules. At initialization of the controller, function keys are transmitted to the I/O modules, the latter which confirm that they are capable of the functions expected by the control program. The I/O modules may change their function according to the function keys and may accept functions not identical to those performed by the I/O module if the I/O module performs at greater functionality.
