Causes of runtime errors for macros
At runtime, the application logs errors and warnings about macros to diagnostics under these circumstances:
- problems reading the macro file or the expression
- problems writing to the tag
- problems communicating within the project or with the data source
The application also sends information messages to diagnostics when an expression in a macro is read successfully, and when a value is written to a tag successfully.
TIP:
Because macros are not necessarily run in the order in which they are listed, do not rely on the order of execution to control your process.
