18.2: Discrete I/O Driver Configuration

There is not a standard discrete I/O driver configuration table but some fields are common across different drivers. The discrete I/O driver configuration table is typically an array of structures with each structure containing the information for a particular board. The following is a list of the type of information normally required to configure an discrete I/O board:

board_offset: is the base address of a board.
relay_initial_values: is an array of the values that should be written to each output word on the board during initialization. This allows the driver to start with the board's output in a known state.
