Post by sturmghost on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
You could work around this problem by implementing some sort of "state machine". Each dialog sets a boolean variable when they are closed so you know which dialog was closed. Then you can react to this accordingly.

Post by ryusoup on JSONByteArrayWriter problem? ^{CODESYS Forge talk (Post)}
Hello, I am trying to implement a FB to make JSON formatted WSTRING type message using JSON Utilities 1.9.0.0 included in the IIoT library. In my case, I want to set some objects or arrays and set values to them later. But when I wrote as the sample below, // init builder builder(pJsonData:=pJsonData, diRootObj=>diRootObj); // set the 1st key to root diKey1 := builder.SetKeyWithArray(wsKey:="key1", diParentIndex:=diRootObj, eError=>eError); // set a value to the 1st key wsValue:="value01"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey1, eError=>eError); // set the 2nd key to root diKey2 := builder.SetKeyWithArray(wsKey:="key2", diParentIndex:=diRootObj, eError=>eError); // set a value to the 2nd key wsValue:="value02"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey2, eError=>eError); // set a value to the 1st key again wsValue:="value03"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey1, eError=>eError); // set a value to the 2nd key again wsValue:="value04"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey2, eError=>eError); // write build result writer(xExecute:=TRUE, pwData:=ADR(wsResult), udiSize:=SIZEOF(wsResult), xAsyncMode:=FALSE, jsonData:=pJsonData^); the result was: { "key1": ["value01"], "key2": ["value02", "value03", "value04"] } while my expection was: { "key1": ["value01", "value03"], "key2": ["value02", "value04"] } Inspecting pJsonData^, JSONData itself seems to be ok, so I believe the issue is something caused by the writer FB. Does anyone know how to fix it? Thanks,

Post by riccardo on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
GoodMorning everyone. I have a system that, in case of alarm, have to block. When the operator logs in must have to acknoledge the alarm and should operate in the system freely. To perform this I detect the logged User by (VisuElems.CurrentUserGroupID <> 0) with a similar code to the the following: PROGRAM AlarmMngt VAR alarm : BOOL:= FALSE; Ack : BOOL:= TRUE; PushBottonOpening : BOOL:= FALSE; Valve : BOOL := FALSE; Flag: BOOL := FALSE; END_VAR IF alarm AND Ack AND (NOT Flag) THEN valve := FALSE; PushBottonOpening := FALSE; Ack := FALSE flag := TRUE; ELSIF (NOT alarm) AND Ack THEN flag := FALSE; END_IF (* if the system is in alarm but there is a logged operator that acknowledge the alarm the system allows the valve opening.*) IF (VisuElems.CurrentUserGroupID <> 0) AND Ack AND Alarm AND PushBottonOpening THEN Valve := TRUE; ELSIF (VisuElems.CurrentUserGroupID = 0) AND Alarm THEN valve := FALSE; END_IF The problem I have is in the last 5 lines of the code: Even if there is a logged in user, the GroupID variable is subjected to a refresh that cyclically set for an instant it to 0 and this close the valve making difficult to the user to work Now I solved it creating a time hysteresys cycle but it is not a good solution. Someone is able to explane me why the GroupID variable is sobjected to this refresh and how to stabilize to avoiding it? Thank you in advance, Riccardo
