Posted 18 May 2015 Hello Everyone, In PCS7 hardware configuration, I have connected IM153-2 FF link to a profibus master connected with CP443-5 Ext. And afterwards I have connected the field instrument with FF communication with the slave bus on FF link. However I am not able to delete the equipment once connected. The error is showing as the object is locked. How to unlock and delete the objects which were takes for testing purpose. Thanks in Advance, GJ Share this post Link to post Share on other sites
