Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

I took a look at your project. First of all, a Raspbery Pi4 is installed. You must use the GPIOs_A_B(GPIOs B+/Pi2). The error ULINT can't be set to IDINT.... with your project as well. If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’ the error is gone.

It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

Hello, I'm running the lastest version of Codesys 3.5 SP20 Patch 5, with the lastest version of Chrome. And I still get this "Webvisu not supported due to missing browser feature HTML5-Canvas" fallback with a quite simple webvisu containing some buttons, images, textboxed and a grid. What can I do? is that a configuration to change? Thanks!

In your soft plc folder, there is a file called targetvisuextern.cfg. Open this with a text editor to change the settings. Remove the semi-colons in front of the lines to enable your custom window settings. WindowType=0 means you will get a moveable window. Save the file and restart the soft PLC to enable these settings.

OK, I figured out that I can simply define all the sensors as 16 bytes IN/OUT, even if they are not all used. EDIT: The negative effect is that each bit is taken into account as an I/O for the license, even if not used.

How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

For anyone with this issue, you may need to: Open the text list properties (right-click the text list once you create it). Select the Text List tab. Change the Download by option to Visualization. I was fighting this for so long. Once you do that, you should find your text list appears in the drop down when editing a visualisation.

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.

Hi imdatatas, thanks for your feedback. This change was intentional, as the quadratic ramp type has many advantages over the trapez ramptype. Sorry to hear it causes problems in your situation. Can you please shortly explain the nature of the problems? Best regards, Georg

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Hello, I don't really know what my problem was, but it's working for me at the moment. All i did was to change my code because of some REAL_TO_INT conversions, like i wrote above. And later a complete new Pi setup (because of 64x support with 4.10.0.0 now).

Hello, I think you can try to change the Connection from Multicast to Point to Point. Please also make sure your windows firewall is allowing the correct UDP ports inbound for ethernet IP. You might also need to increase the RPI, so it times out slower.

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) );

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
