TIA Portal V21 combines engineering efficiency with higher plant availability
TIA Portal V21: shorter commissioning, higher plant availability
The
continuous further development of TIA Portal addresses the challenges of
industry: ever shorter product lifecycles, increasing variant diversity and a
growing shortage of skilled workers requiring flexible, easy-to-use engineering
tools that simultaneously guarantee the highest software quality.
As an
integrated framework, TIA Portal combines all automation tasks in a single environment,
offers open interfaces for IT/OT integration (Information
Technology/Operational Technology) and supports testing and simulation
functions including digital twin applications. TIA Portal stands out thanks to
a consistent user interface, comprehensive visualization options with SIMATIC
WinCC Unified and freely selectable deployment models – on-premises, by
subscription, or in the cloud.
Horst
Kayser, CEO, Factory Automation at Siemens Digital Industries, said:
“With TIA Portal V21 we are accelerating the transition to software-defined
automation. Git-based CI workflows shorten development cycles, while
high-availability SCADA architectures ensure that our customers can keep their
plants running more efficiently and adapt them flexibly to new market
requirements.”
Greater efficiency in engineering through improved and integrated workflows
TIA Portal V21 focuses on higher engineering efficiency and end-to-end standardization. A new export format enables seamless integration of established version control systems such as Git for the first time. This applies to LAD, FBD, SCL, data blocks, PLC data types and mixed-language blocks and many others. This enables STEP 7 users to benefit from optimized continuous-integration workflows, simplified versioning and maximum compatibility. All of this forms the basis for shorter project runtimes and reliable traceability of all changes.
Higher availability thanks to SCADA architecture
Supervisory Control and Data Acquisition (SCADA) applications
based on WinCC Unified can now be operated in redundant server architectures
that ensure continuous operation and significantly higher availability. In
addition, the WinCC Unified Data Hub, acting as a central archive, provides
access to and long-term storage of production data, messages and audit trails
from multiple WinCC Unified PC runtimes, helping to create continuous,
plant-wide data transparency over long periods of time.
