Methods and apparatus to implement safety applications associated with process control systems

Providing a plurality of available safety applications for implementation by a safety trip device 110 associated with a process control system (100, fig 1) to a user for selection (132, fig 1), the safety applications being self-contained and defining a complete set of logic functions and operations implemented in association with a set of I/O signals. Logic functions and I/O signals of different applications being different. The safety applications are implemented based on pre-programmed instructions stored in a memory which define the logic functions. In response to a user selection of a first safety application, the user is prompted to specify values for configuration settings associated with the safety application, the first pre-programmed instructions defining the configuration settings. The safety application is implemented based on the values for the configuration settings specified by the user.
