Post by phoward131 on Numpad decimal value requires leading zero ^{CODESYS Forge talk (Post)}
I have noticed on the standard numpad dialog, if a user enters a purely decimal number (ie '.6'), the numpad will not accept the value but gives no indication. One must type a leading zero (ie '0.6') in order for it to work. Is there a way to correct this so that a user can just type the decimal value?

Post by timvh on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
Probably best to call the FB continuously. So something like this could solve it: IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog := FALSE; fbOpenLatchSettingsDialog.xExecute := TRUE; END_IF IF fbOpenLatchSettingsDialog.xDone OR fbOpenLatchSettingsDialog.xError THEN fbOpenLatchSettingsDialog.xExecute := FALSE; END_IF TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog( itfClientFilter:= VU.Globals.OnlyTargetVisu, sDialogName:= 'visu_AlarmLatchSettings', xModal:= TRUE, pTopLeftPosition:= ADR(TopLeftDialog) );

Post by wiresplus on How to display the application name on a visualization (V3.5.16) ^{CODESYS Forge talk (Post)}
Hello! I would like to display the project name on the HMI The project name contains the version number That way, a tech knows which version is loaded on the PLC. Is the a standard way to display this, or do I have to hard-code into the HMI (not ideal)?

Hello. I am a new user. On generating the first test project I am receiving this error message. You are using inconsistent overlay settings, please check your compilerdefines for the current application (-> GENERATE_OVERLAY_VISU) and the setting within the visualization manager. Can anyone help?

Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

I've been making few HMIs and I'm starting to get annoyed that whenever I try to align an object to the left or top side of the frame, it quickly scrolls into that direction infinitely. Is there a way to prevent that?

Hi, Im struggle with making custom button. The idea is simple grey light bulb after touch (input var) it changes to yellow but shows output var status not switch status. So if light is physically on, switched by physical switch, bulb is also yellow. How to do it?

Post by ilya-vah on Table element issues ^{CODESYS Forge talk (Post)}
Hello, First post here. I would like to clarify whether the following behavior is known or if it is a bugs. Issue 1 — First row not displayed when using Maximum array index with 1-based arrays Description: When displaying data from an array that is indexed starting from 1 (e.g., ARRAY[1..N]), and the number of displayed rows is limited using the Maximum array index property, the first row of the array is not shown in the visualization. Steps to reproduce: Create an array indexed from 1 (e.g., ARRAY[1..N]). Bind the array to a Table element. Limit the number of displayed rows using the Maximum array index property. Run the visualization. Actual result: The first array element (index 1) is not displayed in the table. Issue 2 — Tooltip string placeholder cannot be bound to string variable from array Description: It is not possible to use a string placeholder in the tooltip that is bound to a string variable from the array. Steps to reproduce: Use a table bound to an array containing string variables. Configure a tooltip using a string placeholder referencing a string field from the array. Run the visualization. Actual result: Tooltip doesn't show any text. A test project demonstrating both issues is attached. Thank you for your time and support.

Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
The probelm arises for the B&R T30 panel after updating Codesys from 3.5.17 to 3.5.19 patch 5. We have to use 3.5.19 for other reasons so we cannot downgrade the version. The scaling problem only exists for the B&R 6PPT30.0702.20F025 panel, the B&R T50 panel and a esa lumia panel work. When we choose a fixed resolution it looks also good, however we also want to support the esa lumia panel with a different resolution. The images show the anisotropic and isotropic option. In the anisotropic option it scales the hight correctly but not the width and in the isotropic option is scales both hight and width false, it also does not start in the top left corner. Does someone have any suggestion why it does not work anymore with the new codesys version and are there workarounds? I added all versions with visualization packages as an image, visuElems is 4.4.0.0.
