Controlling a process plant comprising one or more objects where the objects comprise means for receiving standard codes with associated parameter value via the data communication means and for changing a parameter in the object, e.g. the real value of the process parameter, the goal for the process parameter or an alarm condition, the object furthermore comprises means for sending standard codes with associated parameter value via the data communication means reflecting a parameter in the object, e.g. the real value of the process parameter, the goal for the process parameter or alarm condition. |
