Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
I came up with an FBD that seems to be working, although it may not be a true Retriggerable Pulse timer. There may be some delay associated with the two MOVE functions and ADD function I incorporated. I'd be interested if anyone is able to come up with something cleaner. I am surprised that this is not a built-in function block of the CodeSYS library. This is a common feature of multi-function timer relays. I also attached a page from the cut sheet of a Schneider relay that shows 10 timing functions. Looks like the CodeSYS library has built-in function blocks for only 3 of the 10.

Post by rk-gaw on Unhandled exception and refactoring error ^{CODESYS Forge talk (Post)}
Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.

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.

Hello, our team is able to use Raspberry Pi on CODESYS, but we purchased two peripherals that utilize I2C and we cannot figure out how to access these devices in CODESYS. But they are working using Python. Does anyone have a suggestion or an existing library that might help support this? Thank you, Jeff

Post by cihangur on Application has invalid license metrics. ^{CODESYS Forge talk (Post)}
Hi, I have a "CODESYS Control Standard L" license and I use Ethercat and Profinet in my project. The project works seamlessly with two fieldbuses. However, when I add modbus_Com (Serial) or 1 OPC Tag to the project, the program throws an exception (Application app=Application has invalid license metrics!). My license should support 10*Modbus and 512 OPC Tags. Why might this problem occur?

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?

Post by bjarne-pagaard on Global Variables ^{CODESYS Forge talk (Post)}
Old thread, I know - but it still has good answers. I would like to add a bit of info to it, as I was having a problem that lead me to this thread, but didn't give an exact answer. I am porting a project to a different PLC architecture. (Wago PFC300) A GVL named 'GVL' in the POUs section of my project was shadowed by a PLC-specific library in the Application->Library Manager. So all the existing references in the device specific code to 'GVL.something' would not resolve. Right-clicking the GVL in the code and 'Go to definition' would point me to the library in the Application Library Manager. All I had to do from there, was right-click the library, and set the property 'Only allow qualified access to all identifiers' in the library.

I can't recall how I solved it and whether it was a problem with my codesys installation or the project itself. If it is the codesys installation, make sure all your required libraries and plugins are installed and available. compare with a colleagues installation if possible.

When you have a deep object structure where not all values are not exposed to OPC UA, the top object will not have a V check mark but be filled fully out. In that case CODESYS do not always registrate changes to inner object. Solution set a V in the checkbox of the top object, build, download. Now you can browse, but all values in the top object will be selected, then you can deselect the ones you don't want, build, download and it works

Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Don't set on SVN. The service phase has started in March 2024 and will be discontinued in 2027. We actually use SVN and have to switch to GIT in the future. As I informed, there is no way of getting a single SVN or GIT licence. I' dont understand, why Codesys forces us customers to pay for an expensive Professional Edition paket from year to year using only one part of it! If you find a way to buy a single licence, let me know.

Post by appling on License status of Linux 64Bit runtime via CLI ^{CODESYS Forge talk (Post)}
Hi, I have a Linux 64Bit system with a Codesys application running on it. It stops after 2hours and a few minutes, which makes me think something is wrong with the installed license. (in my last timing it stopped after 2h4min, on the codesys website it is stated that runtimes without a license stop after 2h) I installed the license via a USB license dongle that I activated on my workstation with the Codesys IDE a while ago. Now the system is shipped at not accessible physically, only remotely via SSH. So is there a way to check the status of the License of the Codesys runtime when it is running on the system? Running the codesyscontrol script with "status" just tells me that it is running, but does not provide any license information. Best regards

Post by mark on IO link on IFM AL133x only single digital input on a channel ^{CODESYS Forge talk (Post)}
I have a problem with the CODESYS IO-Link SL software. When I insert a IO link master AL1332 and plug a discrete digital input to a channel it reads only 1 of the 2 available inputs on that channel. Is there anyone who sorted out if the second input is also usable? When we configure the module without the CODESYS IO-Link SL software then the second input on the channel can be used. At the moment we use some channels on a module as IO-link port, and some as discrete IO. It would be very nice if we can use both inputs on a channel with the use of CODESYS IO-Link SL.

Post by alexgooi on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hi Jack, I think you have to look at a FB in a different way. A Function block (Class) can contain its own data. In other words don't define loose data in your GVL, but define a instance of a FB (Object) in your GVL: Example: Function_Block Basic_Class VAR_INPUT Open_Command: BOOL; END_VAR VAR_OUTPUT Opened: BOOL; END_VAR if Open_Command then Opened := TRUE; ELSE Opened := FALSE; END_IF Global Variables Objects: ARRAY[1..100] OF Basic_Class; //Here you ar defining you objects END_VAR In your code you can directly acces the data and couple it to the IO: GVL.Objects[1].Open_Command := %IX0.0; %QX0.0 := GVL.Objects[1].Opened; //To call the code itself use: GVL.Objects[1](); If you want to take this a step further you are also able to add methods and properties to the FB/Class end thereby creating a OOIP program

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).
