Causes of run-time errors for macros

At run time 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.
