I'm Having the same issue. If I highlight PLC Logic and import it erases everything else and replaces the Task config. If I highlight the Application I get the same result. Simple manual fix is click and drag the task config onto the origional Application, and delete the second one. Easy fix but not the expected result of importing task config.

Hi, I have got a solution. Go to local disk C. (There will be an option View on top. Click View>Show>hidden items.) go to following path:C:\ProgramData\CODESYS\CODESYSControlWinV3x64 there will be one or two files. delete it and run control win again. issue will be resolved.

You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

At 19.1 the hFile_test should be RTS_IEC_HANDLE and always open-write - close in one cycle udi_handle: RTS_IEC_HANDLE; //handle-number. Is created by SysFileOpen udi_handle:=SysFileOpen(sFileName,Sysfile.AM_WRITE_PLUS, ADR(udi_ErrorCode)); udi_RetValWrite:=SysFileWrite(udi_handle, pRemBuffer, szRemBufSize, ADR(udi_ErrorCode)); //closing file IF udi_RetValWrite < szRemBufSize THEN ui_Error:=cWriteError; END_IF//error writing data udi_ErrorCode_Close:=SysFileClose(udi_handle);

That definitely does the job with the Ladder Logic Diagram type; fully equipped toolbox. Just starting with Codesys and was following programming steps which explains the choice of ladder I had picked. Thanks for the tip and have a good one! Cheers!

Hi guys, I am quite new Codesys. Be patient to me. I am having a problem now. Please refer to the attached photo. Is there a way to increase the memory ? If no, what is the way to solve this problem ? My retain variable list is in one place. Please refer to the attached photo. Thank you very much.

Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.

Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

Post by kimnegw on Codesys offline license batch ^{CODESYS Forge talk (Post)}
Hey guys, I'm currently developing a Codesys application for an offline Linux device. I can easily set up the license for ONE device using my Windows PC, but what happens if I need to produce a thousand devices? Is there any method to automate license insertion? I have already generated a dpkg installer for deploying the Linux control application to multiple targets. Thanks,

Hi there, I am getting troubles with a project. In the Hardware configuration I got some Lenze drives 9400. One of them got as status " Module not Found". Connection are good. ID Node of the Canopen network is also good. I don't find any reason for this status, nor any options to check.

Post by phoward131 on Numpad decimal value requires leading zero ^{CODESYS Forge talk (Post)}
I have noticed on the standard numpad dialog, if a user enters a purely decimal number (ie '.6'), the numpad will not accept the value but gives no indication. One must type a leading zero (ie '0.6') in order for it to work. Is there a way to correct this so that a user can just type the decimal value?

Thank you for your answer! I'm not sure, but it seems this is not what I am looking for. I attached three pictures. The first one is from the Codesys IDE. I use an Information Model to generate an OPC-UA server. I connected via UA-Expert, and there I see the URIs I would like to change.

Hello, Without much info, I would assume that this is an optional object on the EtherCAT network and it's either disconnected or the address doesn't match. I would look into the devices manual or contact the manufacturer for further assistance. And, I would have posted a new topic instead of using a non related one... Cheers!

Hello, I'm using th IDE Combivis studio 6 (codesys based) and I get an error message when I use IO-link. "The license is missing or invalid. The API is running in demo mode." However the package Manager indicates that no licence is required. It used to work, it seems that the free package has become a paying one. Can Codeys confirm this? BR

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Yes, this is the error the sometimes show up. What make me crazy is the fact that it happens randomly and not each times. I know very well where the problem is, in wich one program row it's located. For each actions of the state machine I have all events recorded with log on text file. it is not problematic for me to find the application point of the fault, but I need to understand why occasionally and for no apparent reason, switching the state machine and thus changing the motion FB, sends the axis into failure (but only occasionally). For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?
