You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.

I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Post by krisj on ScriptEngine POU property Get and Set accessor. ^{CODESYS Forge talk (Post)}
Hey! I am trying to generate a function block with properties from a list with script engine. Codesys/ScriptEngine creates both the Get and the Set accessor. I cannot find a way to delete the Set method/accessor. Anyone encountered the same problem or have a solution for this? for prop_name, prop_type in list: property = pou.create_property(prop_name, prop_type) get = pou.find("Get", recursive=True)[i] get.textual_declaration.replace("") get.textual_implementation.replace(prop_name + " := " + struct_name + "." + prop_name + ";") set = pou.find("Set", recursive=True)[i] set.textual_declaration.replace("") set.textual_implementation.replace("") i += 1

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
