On screen error messages

All the operations and functions of the RecipeHelper package are using RecipeManagement APIs to access the server.

Any errors occurring during the execution of JavaScript are in client environments and are not logged into the TwinCAT Event Logger. The user cannot see these errors in HMI and must open the browser log window to see them.

The RecipeHelper package provides a utility that displays any errors in a special pop up screen on the HMI. The user can perform the following actions on this error pop up:

  1. Ignore and close the pop up.
  2. Download this error message for logging and contacting support about it.
  3. Reset the communication handshake to retry any operation that failed.
