With SINUMERIK ONE, Siemens has consistently aligned its CNC with TIA Portal and the digital twin. For machine builders, however, project success rarely depends on the controller itself, but on two questions: How quickly is a clean, maintainable PLC program in place? and How well does the operator get along with the machine? This is exactly where BaseProgramPlus and Create MyHMI /Automotive come in.

SINUMERIK ONE at a glance

  • Integrated SIMATIC PLC: The PLC is based on S7-1500 technology and is configured entirely in TIA Portal, together with drives and I/O.
  • One engineering tool: CNC, PLC and drives are brought together in TIA Portal via SINUMERIK ONE Dock instead of several separate tools.
  • Digital twin: With Create MyVirtual Machine, the machine can be commissioned virtually before the real hardware is ready.

BaseProgramPlus: don't reinvent the PLC foundation every time

In many machine-building companies the PLC program has grown over the years: every machine a little different, every programmer with their own style. BaseProgramPlus provides a structured, modular framework for the PLC user program on SINUMERIK ONE that already covers typical basic functions of a machine tool.

  • Proven standard functions: Recurring tasks are not programmed from scratch but integrated and parameterised as proven blocks.
  • Uniform structure: All machine types follow the same layout. Anyone who knows one machine immediately finds their way around the next.
  • Focus on what matters: Development time goes into the machine-specific logic, where the machine differs from the competition.
  • Easier service: Commissioning and service engineers work with a familiar structure, even years after delivery.

The benefit is greatest when several machine variants or an entire product line are built on the same foundation.

Create MyHMI /Automotive: operation that fits the plant

The standard SINUMERIK Operate interface is powerful, but it shows everything a CNC can do. A machine operator in series production, on the other hand, mainly needs the functions for their task, quickly accessible and without detours. With Create MyHMI /Automotive, operator interfaces can be designed that are tailored to the requirements of the automotive industry and its suppliers.

  • Task-oriented: Screens for setup, production, troubleshooting and maintenance show exactly the information needed in each situation.
  • Consistent across machines: OEM plants in particular require the same operating concept for machines from different manufacturers. This shortens training and reduces operating errors.
  • Integrated rather than alongside: The interface fits into SINUMERIK operation and accesses NC and PLC data directly.

For smaller extensions, Run MyScreens is often sufficient. If you need complete freedom, for example for complex add-on applications, you can develop your own programs with Create MyHMI /3GL. The choice of tool therefore depends on how far the interface should deviate from the standard.

The combination makes the difference

Both building blocks deliver their full benefit together:

  1. Clean data foundation: BaseProgramPlus provides states, messages and parameters in a uniform structure.
  2. Clear connection: The user interface accesses this structure. New machine variants get the right screens without much extra effort.
  3. Test virtually: With the digital twin, PLC logic and operating sequences can be checked before the machine is assembled. Errors that would otherwise only show up during commissioning are fixed at the desk.

Recommendations from practice

  • Start with the operator: Before designing the first screen, clarify which tasks actually occur at the machine and how often. This determines the menu structure.
  • Define standards early: Define naming conventions, message texts and colour scheme once and use them for all machine types.
  • Plan for multiple languages: Keep texts translatable from the start if machines are going abroad.
  • Maintain versions: Version PLC blocks and HMI projects together so that software and interface always match.

Conclusion

SINUMERIK ONE provides the technical foundation. With BaseProgramPlus, a uniform, maintainable PLC program is quickly built on top of it, and with Create MyHMI /Automotive an interface that operators understand without lengthy training. Together they save engineering time, shorten commissioning and make the machine more attractive to customers with demanding plant standards.
