Siemens has introduces some innovations into Step 7 in New TIA Portal. Main ones are:
- Continuous Integration: new LAD export/import format
- Online features for named value data types
- Named value types used by safety blocks and in type libraries
I covered most of them in our video – link below
New export format for LAD blocks, DBs & UDTs
note: It will be available with next TIA Portal update.
Named value data types within Software Units – Online improvements
Since TIA Portal V19 user can create within Software Units data types with named values (NVTs). Now during online actions like monitoring and trace, we display the values such as the defined and meaningful names.
The trace recognizes NVTs directly in trace definition.. Recorded values in the diagram are automatically resolved to NVT definition and displayed accordingly.
Increased nesting depth for structures
For S7-1500 >= 4.0 the nesting depth for PLC data types, STRUCT tags, and ARRAY of STRUCT/UDT
tags has been increased from 8 to max. 26 elements
Using an ARRAY of STRUCT/UDT, which requires 3 hierarchical levels each, reduces the maximum nesting depth accordingly.
Font adoption for title & comments
Font type can be changed for block and network title and comments via Global setting. Using monospace fonts comments can be easier structured
Network titles & comments can be zoomed in / out
Rest of TIA Portal V20 improvements
We tested all above functions, especially ability to disable popup when downloading software. This helps a lot.
There are many more Wincc Unified innovations which will be covered in the near future
