Issue
How many time schedules (time objects: TSCH, TSCHI) can be added to TAC Xenta programmable devices?
Product Line
TAC VistaEnvironment
- TAC Xenta 301, 302, 401, 281, 282, 283
- TAC Xenta 527, 511, 711, 721, 731, 701
- Menta
Cause
The limits for time schedules are not clearly documented across all TAC Xenta controller models, leading to confusion during programming and deployment.
Resolution
Here are the documented limits for each controller series:
TAC Xenta 7xx Series
- Supports up to:
- 50 time objects
- 50 week schedules
- 50 holiday schedules
TAC Xenta 28x Series
- Supports:
- 1 TSCH block
- Up to 16 week/holiday charts within that block
TAC Xenta 30x/40x Series
- No fixed limit on the number of TSCH blocks
- Limitation is based on available memory
- More schedules per block = more memory usage
- Optimize chart usage to conserve memory
🧠 Additional Notes
- When designing schedules, consider memory constraints especially for 30x/40x series.
- Use Menta to monitor memory usage during programming.
- For best practices, avoid overloading a single TSCH block with excessive charts.
