Hello, I have two points about the help in CPS, which is generally great but could benefit from this: 1. Also let me open the help if no project is loaded. Sometimes I just want to quickly open the help files of a specific CPS or OES version but don't want to look for a project that is using this specific version. That is pretty much the only time I open it from start menu directly and then it won't open any project. Problem is that the Help menu only has the About option but none of the other documents in this case. So I always need to find a project of that version or temporarily upgrade another one, just so I can read the help files. 2. The export reference about VariableDrops can be made more precise. It says: What it does not say is that those properties will have the value of -1 if the VariableDrop is an array but the dimension is not in use. I inferred from the documentation that it would also be 0 in that case, but that is not correct. I feel misled 😛 Edit: I was also inaccurate. This is precisely what it looks like for an ARRAY[1..2] OF WORD, so a 1-dimensional array.

@SteffenR- are you sure it wouldn't work with a debounce time? I specifically designed it so it can be used with a debounce time. Please have a closer look again and confirm or deny. The variables _signal1Ok and _signal2Ok are variables of the chain that have to be reset before the respective step. Then I check the return value of WaitIo for OK and then set the _signalXOk to TRUE, which will happen after the IO signal passed the debounce time. If the return value of WaitIo is anything other than OK then it won't affect _signalXOk. The ELSIF then checks if the IO signal does not have the desired state (I assumed it should be TRUE) and then it resets the _signalXOk. This serves as a reset in case the IO signal falls off after the debounce time was passed successfully. Only if both _signal1Ok and _signal2Ok are TRUE the step goes on. This requires that both signals have successfully passed the debounce time and that neither of them has reset before the other passed the debounce.

I think SteffenR's solution is probably the best here. If you don't want to create your own event message or want to retain the original event messages created by BinIo for your digital inputs, then you need to create two FB variables, e.g. _signal1Ok and _signal2Ok. Then the following should work: Step 1: // reset variables _signal1Ok := FALSE; _signal2Ok := FALSE; _retVal := OK; Step 2: // wait until both checks have returned OK one time _tempRetVal1 := WaitIo( your first signal's parameters here ); IF ( _tempRetVal1 = OK ) THEN // remember OK _signal1Ok := TRUE; ELSIF ( NOT BinIo._yourFirstSignal ) THEN // signal lost again => reset _signal1Ok := FALSE; END_IF _tempRetVal2 := WaitIo( your second signal's parameters here ); IF ( _tempRetVal2 = OK ) THEN // remember OK _signal2Ok := TRUE; ELSIF ( NOT BinIo._yourSecondSignal ) THEN // signal lost again => reset _signal2Ok := FALSE; END_IF IF ( _signal1Ok ) AND ( _signal2Ok ) THEN _retVal := OK; END_IF But it's not very elegant, so I'd prefer SteffenR's solution wherever possible.

Hello, I have a small feature request for the VersionHistory.xml. It would be nice to have an optional attribute on the ChangeItem node that can mark this change item as incompatible. Then This change item gets a special highlight or small icon or something in the object browser version history and also when reloading STD in OES/CPS. Reason: I often find myself wondering if I can update to a new incompatible version or if it would be too much of a hassle. So I have to browse the version history, identify which updates were incompatible ones and then scan those updates for the content and try to figure out why this update is supposed to be incompatible, which sometimes isn't easy. A little visual guide would be appreciated. Any chance this will make it into future updates?

Hello, What is "Fixed problem with the changed mechanism of object inheritance" exactly about? What mechanism of object inheritance has changed and what does the fix look like? I'm also regularly building objects and would like to know if there is anything I need to pay attention to in the future. Thank you!
