Configuration Error (PLCN0006): There are too many tasks defined in '...' (current : ..., max. allowed: ...).

In your project, the controller-specific maximum number of tasks is exceeded.

In the error message, the actual number of tasks and the maximum allowed number of tasks are indicated.

Remedy

  1. Double-click the error message to open the 'Tasks and Events' editor of the controller (under the 'PLCnext' node).
  2. Restructure the task configuration: First move program instances to other tasks and then delete supernumerous tasks.
