Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Post by bruceae on Ethernet/IP Scan ^{CODESYS Forge talk (Post)}
Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

Post by ojz0r on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Its important that you know the difference between the two. Example 1: Coils[0] := Coils[0] OR (Buttons[0] AND Sensors[0] > 6); In this case the statements will be evaluated every scan and result in either true or false for Coils[0]. Example 2: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; END_IF In this example Coils[0] will latch the result in a true evaluation, if you want it to behave the same way as example 1 then you need to do it like example 3 below: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; ELSE Coils[0] := FALSE; END_IF However back to the real question. There is no problem using either example 1 or example 3, if im not requiring a latch i usually go with example 1 as it is more compact.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Good morning, I'm digging into this topic because I'm curious about resolving my problem in a test environment. In my previous message, I asked about the CODESYS Safe Timeprovider SL package (4.18.0.0), which I saw in the illustration. I noticed that it runs as a service. I am asking about this because from the perspective of an "ordinary" user, this service provides easier access to the settings of the time provider's operating parameters. The basic time provider configuration is outlined at https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_virtual_safe_time_provider.html. Why my questions? They stem from my specific case, which is experiencing timeout issues. I know that my environment is currently only a test environment. I'm assuming a real-world scenario in which I won't be able to achieve a better result with my configuration, and I will ultimately need to increase the time provider's cycle time. By running the time provider service, I can easily influence the time provider's operation and thus eliminate the problem. I know, I know, safety systems are not life-enhancing extras.

Post by rshabsh on Using Latch Variable in Alarm as input from text list ^{CODESYS Forge talk (Post)}
I am currently utilizing Alarm Manager’s Latch Variable 1 to display additional information related to alarms. However, instead of mapping this latch variable to a fixed PLC variable, I would like to dynamically update its text content based on the selected language in the system. To achieve this, I am considering using a text list that corresponds to different languages rather than directly linking Latch Variable 1 to a PLC variable. This approach would allow the displayed alarm information to be automatically translated according to the active language setting. Could you please confirm if this method is feasible within the Alarm Manager configuration? Additionally, if there are specific steps or best practices to follow when implementing this functionality, I would appreciate any guidance you can provide. Looking forward to your insights.
