METHODS AND APPARATUS TO GENERATE SCHEDULES TO EXECUTE FUNCTIONS IN A PROCESS CONTROL SYSTEM

摘要

Example methods and apparatus to generate schedules to execute functions in a process control system are disclosed. A disclosed example apparatus includes a first interface configured to identify a first function associated with a process control routine. The example apparatus also includes a sub-schedule generator configured to generate a first sub-schedule associated with a first time period. The first sub-schedule indicates a first execution time at which the first function is to be executed. The example apparatus also includes a schedule generator configured to form a schedule associated with a second time period based on two instances of the first sub-schedule. The schedule indicates the first execution time and a second execution time at which the first function is to be executed.
