Post by timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

Post by simotion on Online view : code is scanned ^{CODESYS Forge talk (Post)}
If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Post by timvh on No source code available for this object ^{CODESYS Forge talk (Post)}
The message means that you (CODESYS) tries to open the function block, but this is not possible because the library which contains the FB is compiled. You either get this when you try to manually open the function block (while editing the application), but it could also happen that an exception occurs in the running application and CODESYS tries to show the location where it occured. If it happened in an FB of the compiled library, it cannot show this and you could get this message too.

Post by tvm on SEND_RECV_MSG function block on Schneider Machine Expert ^{CODESYS Forge talk (Post)}
Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Post by kumareasu on Persistent variable storage ^{CODESYS Forge talk (Post)}
Is there any function function block which can store the persistent variable in HDD/SSD immediatley. My observation is that the persistent variable is getting stored when we shut down or restart the system (Windows+ CoDeSys RTE SL ). the persistent variables are not stored in HDD/SSD, if I power off the system without proper shutdown. Seeking your feedback.

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

That is an output of the Function Block ModbusMasterRTU example: xIsConnected=> xIsConnected In this line the VAR ModbusMasterRTU.xIsConnected is written to VAR xIsConnected xError=> is writing to nothing here.
