Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.

What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Can you add a background FB block to the visualization page, and loop through this FB block when the page is in display mode. This FB block requires two more functions, one for executing when the page is displayed and the other for executing when the page is closed.

Call 10 FB instances. Connect Motor_1_Fault to the i_xHW_FaultDetected pin of FB 1, Motor_2_Fault to FB 2... By doing this, your FB will be flexible. The programming will be smooth like a perfect Drift Boss, instead of "hitting the wall" because it can't be reused!
