Configuration Error (PLCN0019): The program instance '...' has a recommended interval time of '...' ms which differs from the interval time of the task.

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.

For partial programs, an interval time may be recommended (defined internally). When instantiating such a program with recommendation, this cycle time is compared with the interval time set for the task. In your project, the set task time differs from the recommended value. The recommended cycle time is specified in the error message.

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. Move the suspected multirate program instance to a cyclic task with a matching interval time or adapt the task interval time accordingly.
