Systems and methods are provided that dynamically render permissive status information on a human-machine interface (HMI) to inform an operator of conditions that are preventing an issued control command from executing. A status display generator deployed on the HMI can be associated with a control action to be initiated in a control program via the HMI. The control action can have one or more programmed conditions or permissives that must be satisfied before the control action can be initiated. Operators wishing to review the states of the various conditions can invoke the status display generator, which reads the conditions and their respective statuses from the control program and generates a permissive summary display listing the conditions together with their respective “ready” or “not ready” states. The permissive summary display provides a convenient reference that allows the operator to quickly assess what actions must be taken to place the system in the appropriate state to execute the desired control action.
