We have a machine where I am missing an "enabled" signal on the WinCC display. With WinCC Graphics Designer I can see that the status bits bits shown on the popup in case are: Høj - DrejeskiveHastighedStatus Bit 0 Lav - DrejeskiveHastighedStatus Bit 0 Enable - DrejeskiveHastighedStatus Bit 9 Fejl - DrejeskiveHastighedStatus Bit 8 This means that the bit I need to make the enabled signal green is "DrejeskiveHastighedStatus" Bit 9 With the Tag Management I can see that address for "DrejeskiveHastighedStatus" is DB2002.DBW26. Opening DB2002 I can see that DBX26.1 is named .Enable but searching for this bit as well as searching for DB2002.DBW26 in the PLC logic finds nothing. When I seach for DB2002 I find a few places that PLC logic is writing to this DB but not to DBW26. So - where and how is bit 9 in DB2002.DBW26 set and how do I find it (also for other signals in the future)? Attachment GH24.zip (154 Downloads)

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
