DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) FIGS. 1 and 2 show an example of the module arrangement 1 as per the invention in the form of a locking safety system. The locking safety system ensures reliable locking of separating protective equipment, for instance a protective door. The module arrangement 1 comprises a locking module 2 that is arranged in a stationary fashion on a frame or the like, as well as a handle module 3 arranged on the protective door with a door handle 3a that can be moved with the protective door. The locking module 2 has a receptacle 2a into which the handle module 3 is inserted when the protective door is closed. The locking module 2 reliably keeps the protective door closed and consequently brings about protection against a hazardous area on a machine or the like.

(7) As FIGS. 1 and 2 show, the locking module 2 can be used in two rotational positions that are rotated by 180 with respect to one another. In the first rotational position (FIG. 1), the receptacle 2a is on the left-hand side of the locking module 2 so that a handle module 3 arranged on the right-hand side of a protective door can be engaged with the locking module 2. In the second rotational position (FIG. 2), the receptacle 2a is on the right-hand side of the locking module 2 so that a handle module 3 arranged on the right-hand side of a protective door can be engaged with the locking module 2.

(8) An expansion module 4 can be connected to the locking module 2 via connection modules that are not shown to expand the functionality. A submodule 5 is connected to the locking module 2 as the base module. The locking module 2, the expansion module 4 and the submodule 5 are connected via a data bus system.

(9) The submodule 5 is also connected to the locking module 2 in two rotational positions rotated by 180 with respect to one another depending on the direction of rotation of the locking module 2.

(10) The submodule 5 has a series arrangement of control elements, namely an emergency stop button 6 and two buttons 7, 8; their actuation initiates certain functions of the locking safety system. The operation of a machine that is creating a dangerous situation can be stopped with the emergency stop button 6, for instance. Specific operating functions of the locking safety system can be realized with the buttons 7, 8. As shown in FIGS. 1 and 2, the orientation of the control elements is independent of the rotational position of the locking module 2.

(11) FIGS. 3a-c show different rotational positions of the base module, meaning the locking module 2 with submodules 5 arranged on it; the individual rotational positions show the transition from the arrangement in accordance with FIG. 1 to the arrangement in accordance with FIG. 2. FIGS. 4a-c show the same rotational positions as FIGS. 3a-c, but with submodules 5 removed from the base module.

(12) As shown in FIGS. 4a-c, an interface slot 9 is provided on the top surface of the housing of the base module that extends in the form of a strip over the entire length of the housing. Two sockets 10a, 10b with an identical design are arranged on this interface slot 9 as connection modules. The sockets 10a, 10b are arranged at opposite edge areas of the interface slot 9. The longitudinal axes run along a straight line forming the axis of symmetry of the interface slot 9 here. The sockets 10a, 10b are connected to an evaluation electronics unit 11 arranged in the housing of the base module.

(13) The submodule 5 is formed by a flat, rectangular body whose area corresponds to the area of the interface slot 9 of the base module. The control elements, meaning the emergency stop button 6 and the buttons 7, 8, are arranged on the top surface of the submodule 5. A plug 12 juts out as a connection module from the bottom surface of the submodule 5; the plug 12 is arranged in an edge area of the bottom surface of the submodule 5. The plug 12 forms a connection module corresponding to one of the sockets 10a, 10b of the base module, meaning the plug 12 can be inserted into a choice of the sockets 10a, 10b to form an electrical connection between the base module and the submodule 5. The electrical connection is comprised of a serial interface here that is formed by an I.sup.2C interface in this case.

(14) Furthermore, the serial interface comprises a communication interface. The type and the orientation of the connection unit are detected via the I.sup.2C interface. The communication interface generally serves to exchange data between the connection units.

(15) As an alternative to the embodiment shown in FIGS. 4a-c, the connection modules of the base module can, of course, also be designed as plugs and the connection module of the submodule 5 can be designed as a socket.

(16) Furthermore, a memory element that is not shown, in which data identifying the type is stored, is provided in the submodule 5. The memory element is preferably designed as non-volatile memory. Moreover, an electronic unit, likewise not shown, for driving the control elements and for intake 2a and forwarding of the signals generated by the control elements is provided in the submodule 5.

(17) The individual rotational positions of the base module and of the submodule 5 that are required to turn the arrangement in accordance with FIG. 1 into the arrangement in accordance with FIG. 2 are shown in FIGS. 3a to 3c or 4a to 4c. For the sake of clarity, the rotational position of the base module is identified with a mark I in FIGS. 3a to 3c or 4a to 4c.

(18) FIG. 3a and, analogous to it, 4a, corresponds to the arrangement of the base module and submodule 5 shown in FIG. 1 in which the locking module 2 is oriented in such a way that the receptacle 2a is on the left-hand side in order to accommodate a handle module 3 arranged on the right-hand side of the protective door. The plug 12 of the submodule 5 is in contact with the socket 10a of the base module in this arrangement.

(19) For the conversion to the arrangement in accordance with FIG. 2, in which the locking module 2 is oriented in such a way that the receptacle 2a is on the right-hand side in order to accommodate a handle module 3 arranged on the left-hand side in the protective door, the base module with the submodule 5 arranged on it is first rotated by 180 starting from the arrangement in accordance with FIG. 3a or 4a; the arrangement in accordance with FIG. 3b or 4b is obtained because of that.

(20) After that, the submodule 5 is rotated by 180 relative to the base module with an unchanged rotational position of the base module so that the plug 12 of the submodule 5 makes contact with the socket 10b as shown in FIG. 3c or 4c. That corresponds to the arrangement of FIG. 2.

(21) Because of the rotational capability of the submodule 5 relative to the base module, a situation is achieved in which the control elements of the submodule 5 are arranged in the same way both in the arrangement in accordance with FIG. 1 and in the arrangement in accordance with FIG. 2 such that the emergency stop button 6 is always on top.

(22) The permissible configurations in accordance with FIG. 3a or 3c can be automatically detected in the base module via a detection of the rotational direction of the submodule 5 in the base module. This detection of the rotational direction is carried out by a detection in the evaluation electronics unit 11 as to the socket 10a or 10b that the plug 12 of the submodule 5 is inserted into.

(23) Furthermore, the type of submodule 5 is detected in the evaluation electronics unit 11 with the aid of data read in from the memory element of the submodule 5, so a determination can be made in the base module as to whether a permissible submodule 5 is connected.

(24) In a learning process, the rotational positions of the submodule 5 on the base module and the type of submodule 5 are input and stored in the evaluation electronics unit 11, so permissible configurations of the base module and the submodule 5, as show in the arrangements of FIGS. 1 and 2, for example, are stored in the base module. This configuration can only be deleted with a factory reset. A high level of security against manipulation is therefore obtained with arrangements of this type.
