Description

The invention relates to a method for linking error messages from software.

The invention also relates to a system for outputting linked error messages.

From the DE 102009027267 A1 a device for error processing on a machine tool is known.

The invention is based on the object of further improving error processing.

According to the invention, this object is achieved in that the software consists of a large number of modules, with a first module triggering the output of a first error message, with the first module transferring a first reference to the first error message to a second module, with the second module Output of a second error message triggers, wherein the second module links the second error message to the first reference by means of the first reference, the second error message and the first error message linked to the second error message being output by the software together.

Linking the error message shows that the second error message depends on the first error message. Thus, fixing the cause of the first error message will most likely fix the cause of the second error message as well. The invention facilitates troubleshooting when operating the machine, since it becomes clear that there are no independent errors. It goes without saying that other error messages can be output in addition to the linked error messages.

In one embodiment, the first module transfers a first error identification message to an output module to output the first error message, and the second module transfers a second error identification message to the output module to output the second error message. The error messages can be known to the output module, so that the error identification messages only trigger the output of the error messages. Alternatively, the error identification messages can contain the error messages, with the error messages being output by the output module.

The second module preferably transfers a link message for linking the first error message and the second error message to the output module, and the output module outputs the error messages linked via the link message and the link of the error messages. The link message can be passed to the output module along with the error identification message. Alternatively, the linking message can be passed to the output module in advance. The link is issued by the output module when the output of the first error message and the output of the second error message are triggered.

The linking of the error messages is preferably output by the way the error messages are displayed. The type of display makes it clear to the user of the software which error messages are linked to one another. The link can be presented to the user in various ways. An example of a type of display is an indentation of the error message one below the other. Other options are numbering, color coding or arrows between the error messages.

The link is particularly preferably output in the form of a sorting of the error messages. The sorting makes it particularly easy to see which error messages are linked to one another.

The first error message linked to the second error message is preferably output indented in relation to the second error message. This makes it clear that a first indented error message was linked to the second error message above it that was not indented.

In one embodiment, the first module reads data from a first sensor and the first error message is triggered by the data read from the first sensor. The error detected by the first module can be based on a malfunction of the sensor or on the fact that the sensor has detected a faulty state.

In one embodiment, the second module reads data from a second sensor and the second error message is triggered by the data read from the second sensor.

In a further refinement, the first module outputs a first status to the second module and the second error message is triggered by the first status. In this way, a sensor read by the first module can trigger an error message from the first module and a second error message from the second module. According to the invention, both error messages are linked to one another. This makes it clear that the error messages are based on the same cause.

The modules of the software are preferably executed on different computing units. This makes it possible to recognize that two error messages from different processors are based on the same cause.

The second module preferably passes a second reference to the second error message to a third module, and the third module triggers the output of a third error message, and the third module links the third error message and the second error message. This links the third error message to the first error message via the second error message. All statements made by the invention about the first and the second error message are also applicable to the second and the third error message. Accordingly, the invention can be applied to any number of links.

The invention also includes a system for outputting linked error messages, the system including a number of software modules, the system being provided and set up to carry out a method described above.

The system preferably comprises a machine tool, the machine tool comprising at least one sensor, at least one software module being provided and set up to read a first value from the sensor and to trigger the output of a first error message based on the first value.

The system preferably comprises a plurality of processing units, each processing unit being provided and set up to execute at least one software module. The computing units are preferably provided and set up to control different elements of the machine tool.

The following description of preferred embodiments serves to explain the invention in more detail in conjunction with the drawings. Show it:

• 1 a schematic view of an embodiment of an architecture of software modules;
• 2 a schematic view of an output of error messages.

Identical or functionally equivalent elements are denoted by the same reference symbols in all exemplary embodiments.

In 1 an exemplary embodiment is shown in which several software modules 10 are executed by different computing units 100, 110, 120. A programmable logic controller 100 executes a first software module 11 , a second software module 12 , a third software module 13 and a communication module 14 . In this example, the programmable logic controller 100 is used to control a machine tool, for example a laser cutting machine, a laser welding machine, a punching machine, a milling machine, a lathe or a bending machine. Additional microcontrollers 110 execute additional software modules not shown here. A processor 120 executes an output module 15 . In this example, the processor 120 is part of a computer that is used to operate the machine tool controlled by the programmable logic controller 100 . In addition to the processor 120, the computer includes, among other things, an input unit and an output unit, for example a screen.

The first software module 11 reads data from a sensor 130 and detects an error. The first software module 11 then sends a first error identification message 21 to the communication module 14. The first software module 11 also sends a first reference 31 and a first status 41 to the second software module 12. The second software module 12 recognizes an error from the first status 41. The second software module 12 then sends a second error identification message 22 and a first link message 51 to the communication module 14.

The second software module 12 sends a second reference 32 and a second status 42 to the third software module 13. The third software module 13 recognizes another error from the second status 42. The third software module 13 then sends a third error identification message 23 and a second link message 52 to the communication module 14.

The communication module sends the first error identification message 21, the second error identification message 22, the third error identification message 23, the first link message 51 and the second link message 52 to the output module 15. It goes without saying that similar software modules can be executed on the microcontrollers 110 or other computing units. It is also understood that the inventive method can be extended to other software modules.

Based on the error identification messages 21, 22, 23, the output module 14 outputs associated error messages. In this example, the error messages are the output module 15 known, so the error identification messages 21, 22, 23 only have to activate the error messages. Alternatively, the error identification messages 21, 22, 23 could contain the error messages. The output module 15 links the error messages based on the first link message 51 and on the second link message 52 and outputs the error messages as in FIG 2 shown off.

2 shows a schematic view of an output of error messages. A message box 201 is displayed on a screen 200 . A large number of messages 210 are output by the output module 15 within the message field 201 . The output module 15 outputs the first error message 211 , the second error message 212 and the third error message 213 , among other things. The first link message 51 ensures that the first error message 211 and the second error message 212 are output by the output module 15 in a linked manner. In this example, the output module 15 sorts the first error message 211 under the second error message 212 and indents the first error message 211 opposite. the second error message 212. Likewise, the output module 15 links the third error message 213 to the second error message 212 based on the second link message 52. The output module 15 sorts the second error message 212 under the third error message 213 and indents the second error message 212 opposite the third error message 213. As described above, the link can also be displayed in other ways, e.g. by means of coloring or arrows between the error messages.
