An industrial controller (100) is disclosed. The industrial controller (100) comprises a controller interface (130) adapted to form electrical connection with at least one module (200), type of which is to be identified, wherein the controller interface (130) has a plurality of contacts, at least two of the contacts (131a, 131b) are each connected to a voltage supply via a corresponding resistor unit (132a, 132b) respectively, and a voltage level of at least one of the at least two contacts (131a, 131b) will be changed after the controller interface (130) is connected with the module (200); and a control unit (140) configured to communicate with the controller interface (130), and identify the type of the module (200) based on the voltage level at the at least two contacts (131a, 131b) after the module (200) is connected with the controller interface (130). There is also disclosed a module (200) to be used with the industrial controller (100), an industrial controller system (300) and a method of using the industrial control system (300). With the industrial controller, the module and the system of the present invention, it is realized that the industrial controller can identify the type of the module being mounted thereon automatically. |
