WinCC Unified Runtime
With WinCC Unified V21 working becomes more convenient and efficient. Optimized tag management reduces project size by transferring only the tags that are actually used, speeding up handling. For legal-for-trade applications, a dynamic SIWAREX widget ensures precise weight display. Email notifications can now be sent automatically for alarms or tag changes, and logs for tags, alarms, and audit trails can be easily exported. Alarm handling has been improved with a configurable indicator that remains visible at all times and supports custom icons for quick recognition of critical states. Additional usability enhancements include automatic focus control during input and the ability to reuse graphic lists across projects for consistent design and standardized engineering processes.

Visualization

• Tag count optimization: download only what you use can be selected
• Advanced tag ranges with Upper2/Lower2 for critical limits & threshold
• Use tag Limits and Threshold for screen objects e.g. Trend, Bar, Gauge, IO
• Read threshold and limit values from HMI tags via script
• Dynamic widget for legal-for-trade SIWAREX weight display

System functions

• Start programs with UI via system function – even in kiosk mode (PC)
• Send emails on alarm or tag change via system function
• Export Log via system function for Tag, Alarm and Audit Trail
• Direct input enabled by focus after screen load (Unified Comfort Panel & Unified PC)

Alarming

• Alarm Indicator – Always Visible, Always Reliable and customizeable with own Icons

Operation Usability

• Logging: Periodically create Backup of Main Database
• Runtime language dependent fallback font
• Reduced project size by removing unused language fonts
• Identify HMI tags by configurable display name
• Automatic handshake for fast data transfer and trend display
• - Integer-based Discrete Alarm Support for 3rd Party and SIMATIC Systems
• - Improved readability of alarm texts through multi-line wrapping of all alarm rows

Standardization

• Reuse and Version Graphics Lists Across Projects
• One Faceplate for All Compatible Data Types
• Direct parameter type configuration via faceplate interface
