    摘要： An apparatus, system and process is provided from communicating safety-related data, over an open system, from a sender to a receiver. Safety-related components, including function blocks, flexible function blocks, resource blocks and transducer blocks, as well as, safety-related objects are provided. Also, a time synchronization monitor is provided for monitoring timing distributions and determining when such distributions have drifted beyond an acceptable limit.

    摘要： An 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.
