ABSTRACT:
A safety qualified interface device is interposed between an operator manned control position having an operator interface and qualified safety system logic monitoring and control devices. This microprocessor driven interface incorporates a memory carrying a library collection of valid safety directives as well as valid parameter inputs and permissible parameter deviation ranges. Control or parameter requests are asserted by the operator from non-safety related but conveniently positioned interface devices at the control position which are treated as trial inputs which are matched at the interface with memory retained valid directives and parameters. Where a match between memory retained data and the trial input signals occurs, then the operator is apprised through a qualified safety related display and a corresponding acknowledgement is made to the interface. The interface then transmits either the directive or parameter request to the associated divisional safety related components for execution and/or retrieval.
