Post by paulg on CODESYSControl_User.cfg - link to documentation? ^{CODESYS Forge talk (Post)}
Is there somewhere in the Codesys help files that generally details what configuration options are available for this file, and what details it logs regarding the configuration file? Or is that going to differ by libraries being used? Thanks!

Post by valenting on License problem with Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I have a raspberry pi with a license installed, but Codesys stops after 2 hours, and when I start it manually I have the following message: pszInfo=!!!! no runtime license - running in demo mode(~2 hours) I tried using License Manager, and got the following message: Licensing info not available. There is no dongle attached to the device. I have this message frequently, and usually removing the content of /var/opt/codesys/.cmact_license makes it work. After doing it and restarting Codesys, I have an empty Softcontainer without my License. I tried using "Install license" using the .WibuCmRau file for the corresponding license and got the following message: Licensing info not available. The device does not support this service. I also tried using Additional Functions > Restore Licenses with the Ticket ID and got the following message: This device does not support automatic license backup. How can I reinstall the license to this Raspberry Pi?

Post by askic on Generate FBs from source ^{CODESYS Forge talk (Post)}
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

Post by mabac on No file found ^{CODESYS Forge talk (Post)}
CODESYS introduced many cyber security related changes over the last few years, one of them is to restrict file access. By default, file access is restricted to the PlcLogic folder and subfolders of the CODESYS control runtime of version 3.5.19.0 and newer. For Control Win this would be the folder C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxxxxxxx\PlcLogic\ To enable access to other folders, you can configure additional paths by adding them to the file CODESYSControl.cfg. For example: [SysFile] FilePath=C:/temp/test FilePath.1=C:/Users/Public You should now be able to access your file in C:\temp\test\ or in C:\Users\Public

Post by rickmotion on Opening and saving files with fileOpenSave dialog ^{CODESYS Forge talk (Post)}
I have a customer that types in machine programs in a text file for machines and lets the machine execute it. In the old situation they can open and edit these files in a winform application. Now I want to move this to codesys. What I need is a simple way to open, close, save, edit the machine file in codesys visualisation. I want to use the fileOpenSave dialog. But don't understand how it works. I have the file transfer example and some other examples. But it is hard to figure out how the part with the file dialog works so that you can select a folder or file. Does someone know how that works?

Hello, I used to connect into my gateway using control SL tool 4.13, (it was called Update Linux.) I formated my computer, so today I install the new version of codesys and all package. Now I am not able to connect to my PLC using control SL. It says, check the status. Normally it used to worked perfectly before that.

Post by atcprojectteam on Modbus Function Code 15, writing multiple coils ^{CODESYS Forge talk (Post)}
Hi all, I am using an RSTI-EP I/O card along with the EPXMBE101 Modbus/TCP network adapter. I have a Control Standard L license. I successfully connected to the I/O card via Modbus and can read inputs without any issues. However, when I try to write to the digital output modules using function code 15, I am unable to make any changes. Here’s what I have done so far: I created a small project using Structured Text. I set up Modbus channels (as shown in the attached image) and mapped the pins. When I use cyclic mode, the connection results in an error. However, when I use the rising edge, the connection works, but I don’t see any changes on the I/O card. For the output module, I assigned one bit to high. After that, I ran CODESYS Control Win V3. (Should I be running the PLC as well?) I built the program, but I am not receiving any response from the I/O card. Could you please advise on what might be causing this issue?
