Automotive manufacturer reduces costs by using AIDYMO and expeccosystems

Acceptance and testing of production systems

The acceptance and testing of production systems takes a lot of time and involves considerable costs.
costs. In order to speed up this process and thus significantly reduce costs, a well-known car manufacturer in the region and eXept Software AG have jointly developed a solution.

The requirements for testing the MDE/BDE interface (machine data acquisition/operating data acquisition) were data acquisition) were:

  • Reduction in the number of acceptance procedures that have to be commissioned externally.
  • Automatically check configuration data at an early stage and simulate the interaction of components.
  • Test the system regardless of the installation status.

These requirements were fully met by using the products AIDYMO and expecco from eXept Software AG products. An online portal is now provided for transmission with AIDYMO, which is used to upload configuration data for validation. The data is then automatically verified with expecco on the basis of existing rules. Existing .NET and Python software libraries were integrated into expecco for this purpose. An error report is generated and sent promptly.

By using AIDYMO and expecco, large parts of the acceptance process were largely automated. As a result, the inspection is much more comprehensive and finer-grained, so that quality of the acceptance has been significantly improved and the time required has been reduced by more than 80%.

Offline acceptance procedure for a production plant:

  • The suppliers of the system provide the description of the machines in various files:
    • HMI (Human Maschine Interface).
    • Sequence control (PLC) as a Siemens TIA file.
    • Configuration files in Excel format.
  • Selection of HMI, TIA and configuration files by the user via an input screen (AIDYMO).
  • Subsequent offline test in 3 phases (expecco):
    • Opening and unpacking the test data and carrying out a preliminary check.
    • Detailed analysis of the HMI, PLC and system signalling logic and automatic generation of a customised test plan.
    • Carrying out the actual production plant inspection.
  • Documentation of the results both as a PDF file for the user and in machine-readable file formats.

Motivation for using AIDYMO/expecco:

  • Offline acceptance: Ensure machines are ready for acceptance. App for Check.
  • Supplier: Fast project completion through rapid acceptance with clear criteria.
  • Project: Ensure that the systems fulfil the required machine functions 100%.
  • Transparency of software quality across all trades.
  • Ensuring software quality through automation and standardisation.
  • Creation of complex scenarios without programming knowledge (graphical modelling of test plans using ‘drag & drop’).
  • Cost savings through efficiency and transparency.
