Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
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.

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 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

Post by pradeepradha on Update Raspberry Pi option is missing under Tools menu ^{CODESYS Forge talk (Post)}
Hello, the option to update Rasberry Pi from under the Tools menu is missing in my installation. Currently I have the build 3.15.19.50, along with the Pi package 4.11.0.0. But the same problem is observed even with the latest build and Pi packages. I have tried clean install with both the versions but cannot solve the issue. I never faced this on Windows 10, but now the new PCs are with Windows 11 - this is the only difference. How can I solve this problem?

Post by timvh on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
If your Control Win is the Modbus "Master" then your configuration should be something like: Modbus_COM (Serial port) - Modbus Master (this is the Control Win SoftPLC actively setting up the communication) - Modbus Slave (this is then your WAGO 750-315) You need to add channels to the Modbus Slave configuration to inform the master which variables to read/write from the Wago module. The way you configured it now, the Control Win is also a slave. PS, don't forget to put the PLC (Control Win) in Run.

Post by jinlee on Camera RTSP Feed ^{CODESYS Forge talk (Post)}
Hi, I followed your guidance and used go2rtc. There is a link generated from go2rtc I can copy into the web browser element in the visualisation. It somehow only appear within the software when it is running, but not on the webvisu. I want to display the camera feed onto the webvisu. My camera is reolink 810a which supports IP protocol. My project is pretty simple, just a web browser element with assigned URL.

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
The RTE will take the RTE license. The HMI will take the HMI license. For the Application Based Licenses, the Runtime will take the smallest which is required. So if you have an application running EtherCAT and no visualization, only the Control with support for EtherCAT is used. If you have another runtime which requires the visualization, it will take the smallest Control license which is required and available + the smallest visualization license which is required.

Post by bzzz on Connect WS2812B Light Strip to CodeSys via RasPi ^{CODESYS Forge talk (Post)}
Hey guys, I have a RasPi and can control my WS2812B (addressable light strip) via Python. The lightstrip is this one: https://core-electronics.com.au/1m-rgb-led-strip-ws2812b-144-per-meter-white-strip-weatherproof.html What I would like to do is to control it directly via CodeSys through the plc on my RasPi. I know I can run a python script on CodeSys, but I'd like to avoid doing that. Is it possible, and how do I do it? Is there a library that does this?

Post by trusty-squire on Display Units/Scale on Path3D visualization ^{CODESYS Forge talk (Post)}
Hi, Is it possible to display the units along the X,Y axis of the Path3D element? It correctly shows the CNC path to be followed, but there's no indication of scale or size of what's being displayed. I looked at the documentation and my first inclination is that this is not possible, and the option option would be to somehow recreate the Path3D functionality into the XY Chart visu element - which is not ideal. Any suggestions or pointers would be appreciated!

Post by ph0010421 on Task time too fast? ^{CODESYS Forge talk (Post)}
Hello I've made an FB which is a TCP server. It uses the excellent CAA NetServices library. If I have the FB in a task <4ms, then the RT crashes immediately at boot up. If the task >=4ms, it starts and runs perfectly. This is even if the block is not doing anything; just instantiated. Am I missing something silly? Why would a low task time cause this? 4ms is perfectly adequate, but I'm just interested why... thanks PH
