Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? I don't have the answer to this question. One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task Yes. It was the exeption you can see in attached file.

Hello, I am getting the following error and warning when trying to download a project into a PLC: - Library CmpTargetVisu has not been added to the Library manager, or no valid license could be found - Unkown type: 'CmpEventMgr.EventParam' As far as I can see, both are included, and licensed, in the library manager (see image). What could the problem be, and how would I resolve this?

Post by askic on PLC error log help ^{CODESYS Forge talk (Post)}
Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

We are connected IFM CR711S to Exor EX710. We are exchanging data using network variables. Both devices are configured on same project so no need to use file source. When tested application it works fine. But after 3 months same application not working. We are able to send data from CR711 to EX710 but data from Ex710 to CR711s works only for one scan when we cold reset CR 711S. Can somebody help to find out error.

I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe

Update: I started over. I saved progress at each step. all compiled zero errors, zero warnings. Pre-processor messages remain, but I can make progress. Until I try to re- load the project file in Codesys. Re-loaded files error as above when compiled, even though they compiled error-free immediately before saving. Is my installation borked? (Not easy to re-install due to IT madness...)

However, when I want to open the html5control.html in the editor or create a new project myself, I always get this error: default filesystem storage could not be found.

Post by matthew on New Ladder Editor Issues ^{CODESYS Forge talk (Post)}
Hi There, When using the new ladder editor there is no option for function blocks to Remove uncalled FB call parameters. I also see no update function block. When you double click the function block it no longer opens the function block. I also now get warnings if I insert FB call without a contact in front. Warning is: (Impl)): C0373: Expression or part of it has no effect I take it the new editor must work differently? The only reason for using new ladder editor is the ST execute/block editing is far better, If you have alot of text in the old ST execute the editor window is very small and when online it's even worse. The new ST block seems a lot better Thanks!

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 andrebrandt on FB string and naming ^{CODESYS Forge talk (Post)}
Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?

Hallo zusammen, seit dem Update des Packages Codesys LB/FBD von Version 4.2.0.0 auf 4.3.0.0 bekomme ich beim compilieren folgende Fehlermeldung (siehe Screenshots). Hat jemand eine Idee was die Ursache sein könnte? Der rechte Baustein ist eigentlich ein FB aber die Instanz wird beim compilieren einfach entfernt. Edit: Wenn ich die Ausführung des rechten Bausteins in einem Execute mache, dann wird fehlerfrei compiliert.

Post by trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
OK, that makes sense. Because the FB is provided a specific interval period, it would change the target position accordingly based on the time it "thought" elapsed. If it has the wrong interval provided, it updates the target positions every cycle incorrectly so the axes will end up moving faster or slower. Thanks!

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Just a stab in the dark, but you might want to check the Dynamic Limits (accel, decel, velocity, jerk) in the Codesys SoftMotion device configuration, as well as checking similar limits on your servo drive? Are you seeing any errors, or does the MC_SetPosition FB get marked as complete?
