Hello , When FB41 is existing in Blocks folder(by calling once or just copying),try find it in the ""FB Blocks" in the programming element in left side of editor.See the attachment. The easiest way is to select different DBs(for 2 control loops) with different names in Symbol Table.More options are discussed here: Different ways to call PID controller' FBs PID Control Package - FB41 Samples I hope that helps you Best regards Hamid Hosseini Attachment fb41.jpg (232 Downloads)

If you attempt to import once again it asks you to overwrite or to store it with different name, so say no. FBs that are located in your project directory, you can use times you want, with different onstance DBs, of course.

The error is nothing but it is just an acknowledgement of FB41 already present in your program. No need to change the name you can simply go for copy paste only. Hope this will help you for solving the issue.
