ONE digital standard – for every machine

Roadmap to innovation: SELMO Standard

 Different programming paths do not lead to the goal in automation, but a dead end. If different standards are developed at high costs, the question of cost arises again with every change – especially if they have to be purchased externally. In such cases, the idea of saving money usually prevails and innovative innovations fall by the wayside. SELMO designs the SPS standard uniformly, open to change, and thus as a roadmap to long-term innovation. And that in the entire value-added process.

Increasing automation is bringing internal and external participants in the value chain even closer together. This makes it all the more important to make the programming system hardware-independent and to establish it from the supplier to the downstream customer. This costs a lot of time, money, and sometimes persuasion. Unless the standard already exists and has proven itself in practice. SELMO operates machines universally via a standard that was developed based on experience in the automotive industry. This industry has long shown how sensible it is to view a machine not as an individual unit consisting of screws and processes, but as a constant sequence of states that can be controlled digitally. This perspective allows machine operators and their implementers to concentrate fully on the automation logic, model each process and pass on the underlying standard to their suppliers and customers. Each machine model can be changed and extended, realigned, or inserted at any time at another point in the value-added process. Besides, SELMO simplifies the operability of each machine via an automatically generated, programmable logic controller and ensures maximum functional stability through bit-precise display and monitoring. This results in time and cost advantages that no longer need to be explained to suppliers and downstream units. 

SELMO eliminates:

 

 

  • Complex awarding processes
  • Long service life
  • Manual specifications with “expiration date"
  • Complicated implementation processes
  • Process delays in the value chain
  • Inaccurate digitisation measures
  • Incompatible and unproductive machine processes
  • Regular errors

A model for the automotive industry? Lesson for digitalization

More models, shorter cycle times, a dense supplier system, and a high degree of standardisation: the automotive industry was not the inspiration for the development of the SELMO standard without reason. Even though automation has gained ground via uniform standards, many complex processes are still often designed via different control specifications that are programmed manually.
This is error-prone, cost-intensive, and slows down every process step in an already small-scale value chain. In the conception of the standard, the SELMO team, therefore, concentrated from the outset on standardising generally valid functions and structures of machines and developing a common control language for all machines in the entire value chain. Because the standard is automatically translated, i.e. algorithmically generated, by the patented SELMO process, it is also adhered to.
Plant operators and process experts can use the SELMO method of process-logical modelling to focus on their core competencies – without any friction loss in project planning and without having to constantly reconcile fundamental requirements.

Zero is zero and one is one

Because bits know no differences and do not speak a “dialect”, SELMO functions completely independent of industry and hardware.

SELMO makes the experience from the automotive industry applicable in every industry and machine. This makes every company independent of specific hardware specifications and maximizes the flexibility and adaptability of processes. This creates room for innovation – at a fraction of the other development costs.
