Configuration Error (PLCN0016): The program type '...' can be instantiated only once.

An error has been detected in the instantiation of a Matlab® multirate program. Such programs may consist of several partial programs. Each partial program must be instantiated separately. As they can be assigned to different tasks (of the same ESM) in your solution, different update cycles can be used within one model. Such programs are referred to as multirate programs.

In your controller, one partial program of a multirate program has been instantiated more than once. This is not allowed.

For more information refer to the topic "Matlab® Integration", section "Multirate programs consisting of several partial programs".

Remedy

  1. Double-click the error message to open the 'Tasks and Events' editor of the 'PLCnext' node in the PLANT. The suspected table line is marked.
  2. Delete the invalid multirate program instance.
