Abstract
An apparatus, system and process is provided for 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.
