Modern production plants only work as well as the associated software. Therefore, we modify the software suitable to your plant or create a complete new one.


  • Software engineering (SIMATIC Step 7 and TIA, Beckhoff, SINUMERIK 840D, etc.)
  • NC features with the SPS (NC emulation)
  • Conception / Projection of CNC control systems for automation
  • Interface programming
  • Robot programming


The usability of a machine mostly depends on its operator surface. Thanks to our efficient operating concepts an optimal usability is given at any time e.g. during the production but also during maintenance works and fault corrections.


  • SIMATIC WinCC flexible
  • HMI pro
  • Beckhoff
  • Visualisation in form of Windows applications (PC based automation)


The virtual commissioning provides great benefits to our customers, as development and commissioning times are shortened and a significant increase in efficiency is achieved.   


  • Creation of a digital twin
  • Simulations
  • Virtual commissioning of SPS, CNC and Robotic


After mechanical completion of the plant, we start with the commissioning of our software which has been previously prepared. Thanks to the extensive experience of our employees, we can guarantee the shortest possible operational readiness until to the hand-over of the plant.


  • Commissioning of our software at customers’ locations all over the world
  • Execution of feature enhancements at plants
  • Training of customers’ staff
  • Identification of process and cycle time improvements
  • Consultation of customers’ staff in case of technical issues


Process control systems are already standard in the era of industry 4.0. Our experienced software engineers are pleased to consult you during an individual and personal interview.  


  • High-level language programming
  • ERP and MES connections


We regard ourselves as niche provider for the design of special solutions in the automation sector as well as for modifications, for modernisation or extension of existing plants.  


  • Mechanical and electrical concept creation
  • Design according to customer’s specifications
  • Supply of a complete functional unit (mechanical & electrical)
  • All-round carefree package – made by HDAO


Due to our employees’ extensive market knowledge in Asia, we also provide special services to our customers on the Asian market. Production in China often makes sense in order to keep the supply chain efficient.
