Composant de régulateur destiné à être utilisé dans un Système d'automatisation industrielle

摘要

The invention relates to a controller module (PID_Temp_1, PID_Temp_2, PID_Temp_3) for use in an industrial automation system, the controller module (PID_Temp_1, PID_Temp_2, PID_Temp_3) being used in a cascaded manner for use with a number of similar or substantially functionally identical controller modules (PID_Temp_1, PID_Temp_2, PID_Temp_3) The controller module (PID_Temp_1, PID_Temp_2, PID_Temp_3) can optionally be configured as a master controller, as slave controller, or as a master and slave controller in cooperation with other controllers of the cascaded controller. In this case, the controller block (PID_Temp_1, PID_Temp_2, PID_Temp_3) has a data interface for communication with other controller blocks (PID_Temp_1, PID_Temp_2, PID_Temp_3), wherein the data interface is set up at least for the exchange of information about a manipulated variable limit and a current operating mode during runtime of the control. This solution with a data interface with only one connection for the exchange of information between master controller and slave controller is easier for the user than previous solutions, where multiple connections and depending on the product used and additional logic must be programmed.
