CIL Generator Error (CILG0054): There exists a name conflict between the program organization unit '...' and an interlock with the same name inside the program organization unit.

The CIL Generator has detected an Interlock in the function block type hierarchy which has the same name as the SFC FB to which it belongs. The affected names are indicated in the error message. This is not allowed.

Remedy

  1. In the COMPONENTS area, open the folder 'Programming | Local | Functions & Function Blocks' and locate the affected SFC FB with the detected name conflict.
  2. Rename the Interlock accordingly to ensure that each element name is unique within the current POU and adapt the call of the renamed element within the FB code accordingly.
