The Cascade DataHub and OPC DataHub have a
powerful, built-in scripting language called Gamma. Using
Gamma, you can interact with either DataHub and its data in
various ways, such as:
- Attach scripts to specific data points so the scripts
are run whenever the point value changes.
- Build custom dashboards and summary displays directly
in Gamma scripts to create self contained DataHub
applications.
- Create alarm condition scripts and have them display
warning messages to the user.
- Create Excel readable log files from your live data by
running logging code on a timed interval, or whenever a
point change occurs.
- Connect to ODBC compliant relational databases to
extract data as well as create records from live
data.
- Apply linear transforms on data as it passes through
the DataHub (for example change a temperature reading from
celsius to farenheit).
- Create full simulation programs to test production
systems before you 'go live'.
