LogixNG error handling is configured using Preferences ⇒ LogixNG. The details are at Error Handling. The Error Handling Module makes it possible to implement custom error handling.
The module is similar to the standard LogixNG modules at Tools ⇒ Tables ⇒ LogixNG Modules. The main differences are that the error module is a system module instead of a user module and it is called when an error occurs instead of from a ConditionalNG. It is managed using Tools ⇒ LogixNG ⇒ Error handling module. The error module is not included in the LogixNG Modules table.
