Abstract
Abstract A field bus network of input and output devices is coupled to a control system through an I/O interface module, regardless of their data structures. The I/O interface module is coupled to the control systemthrough a serial communication port. Local input and output devices are coupled to the interface I/O module through a local I/O interface and networked input and output devices are coupled to the interface I/O module through a field bus communication adapter. A different adapter is required for each type of field bus protocol. The interface I/O module includes a microprocessor based device to generate and control the various interactions between the local devices, networked devices, and the controllsystem and also to provide for a visual and status display of the fieldbus and local I/O data local.
