Abstract
A distributed control system wherein status is propagated through the system along with the signal with which the status is associated. The function blocks of the system include rules for propagation of the status through the system. The system may also include function blocks for testing the propagated status to determine if the same is bad and function blocks to force the propagated status to have a certain status. The rules may be customized by the user, for example, to block status propagation through a function block.
