unexpected shutdown of the zenon runtime when a SAP server program with a deleted zenon function linked to it is executed

unexpected shutdown of the zenon runtime when a SAP server program with a deleted zenon function linked to it is executed

Summary

It is possible to link zenon functions to SAP server functions. If this linked function has been deleted, then the property at the SAP server program will correctly show "function deleted". When the SAP server program is executed in the runtime, zenon tries to execute the already deleted function and thus stop working.

Description

It is possible to link zenon functions to SAP server functions. If this linked function has been deleted, then the property at the SAP server program will correctly show "function deleted". When the SAP server program is executed in the runtime, zenon tries to execute the already deleted function and thus stop working.

Solution

To overcome the described situation, zenon will now verify that the function still exists before executing it.
