Post by k2saki on CNC / G01 Speed is very slow (or go-stop motion) in Continuous short segment . ^{CODESYS Forge talk (Post)}
I'm using CAD/CAM that outputs GCode with G01 many short segments from NURBS Curve, only X-Y axis. But CODESYS CNC motion seems much slower ( or stop-go motion ) in simulation mode than F-Value (I checked value from SMC_Interpolator - dVel ). In GCode G01, F value is F500, but movement is very slow, actual speed (dVel) is between 0 to 30 back and forth. I think very old CNC can move like that, but nowadays, a lot of CNC can move smoothly to process free curve ( somethimes option switch ) I tried to use G51 Dxx but I got the same result. My questions are 1) How do I improve CODESYS CNC motion in this case ? 2) How can I graph the sampling from dVel of SMC_Interpolate in CODESYS? From my GCode N2006 G01 X1.4364 Y-14.6847 F500 N2007 G01 X1.6759 Y-14.6768 N2008 G01 X1.9152 Y-14.6486 N2009 G01 X2.1547 Y-14.6400 N2010 G01 X2.3943 Y-14.6090 N2011 G01 X2.6336 Y-14.6002 N2012 G01 X2.8732 Y-14.5716 N2013 G01 X3.1127 Y-14.5634 N2014 G01 X3.3520 Y-14.5410 N2015 G01 X3.5915 Y-14.5336 N2016 G01 X3.8308 Y-14.5307 ...

Post by timvh on License problem gateway ^{CODESYS Forge talk (Post)}
What we are trying to explain is that, yes CODESYS creates the software, but Epis decides how they implement it on their hardware, which runtime version they use and they decide which functionality they support. So it is always a combination of the two. What CODESYS provides is a runtime with options for e.g. visualization or softmotion. Epis could add this softmotion license as default to their controller, but if they don't then CODESYS provides another option with a single license in a "Wibu CodeMeter" container. Eventhough the feature exists, Epis has to add this "CodeMeter" software on their controller to be able to access the licenses in the container. We don't know if they did this. Then finally it depends on what type of runtime is on this controller and which license Epis is using. So if they have an OEM license (not an application based license), then most likely you will need the Softmotion license (not a number of axis). See https://store.codesys.com/en/codesys-softmotion-sl-bundle.html. But to be sure if this is supported by the Epis controller, you must ask Epis.

Post by rringo on Function block not autofilling ^{CODESYS Forge talk (Post)}
I am attempting to place a block and make it an Analog sensor. When I go to change the name like in the instructional video on youtube it does not give me an option to autofill the block with a known configuration. This is a problem I have in Codesys 2.5 and 3.5. Did I mess up the install of the program or need to install a library? Any help would be appreciated. https://www.youtube.com/watch?v=PkJYQeIUmIM&t=136s at time mark 2:15ish The first image is what I can do and the second is what the videos function autofills to.

Post by dhumphries on install codesys runtime on linux ^{CODESYS Forge talk (Post)}
I'm running the 3.5.18.20 IDE, installed the control for linux SL package from the installer. Following the directions here: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_install_runtime_on_controller.html it says: Installing the runtime package with CODESYS on the Linux device Click Tools → Update CODESYS Control for <device> SL.</device> I don't have the update option in my tools menu. I've tried it without opening a project, as well as with a project open that uses the control for linux SL as a device. I have found the update device option by right clicking on the device in the device tree, but this only lets me change the device the project is using not load the runtime on the linux computer. Is there an updated instruction somewhere, or do I need to do some further preparation like install additional packages?

Post by jmorit on CAM Table - Quadratic velocity ramp with jerk limitation ^{CODESYS Forge talk (Post)}
Hello, I'm working on setup a CAM table by using the Codesys CAM Editor. My purpouse is to obtain a quadratic velocity ramp with jerk limitation motion profile, for which i define the accel/decel phases with Poly5 segment type, but the problem is that due to the fact i can "only" adjust until the acceleration, and the jerk is always setup to 0, and i cannot change the jerk values, i cannot achieve the desired results, as i need to generate jerk steps. Is there any way it can be achieved with the editor, or maybe by using PLC runtime code? Thank you in advance for your help BR, Jordi Morito

Post by dkugler on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
I would figure out, how to create a simple html webpage with 2 frames. One frame with buttons to select the plc. A second frame with hyperlink to the webvisu of the plc ("XXX.XXX.XXX.XXX:8080/webvisu.htm"). Selecting other PLC Button has to change the hyperlink in 2. frame. Costs only some time to figure out :-) Or setup a raspberry Pi with small visualization. Set up a button for each plc and add one browser element. Each button writes the URL of the depending plc to the URL setting of the browserelement. Costs 55€ for runtime licence and a Raspberry Pi.

Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Needed to connect to PFC200 via Putty, and open CodesysControl.cfg with “sudo nano /etc/CODESYSControl.cfg”. Then adding following command to the end of file, and use the name you want, save/close CODESYSControl.cfg, and reboot your PLC. [CmpOPCUAProviderIecVarAccess] CustomNodeName= PFC200 Hi! , I'm digging up this issue cause we have still this long name within current versions on CodesysControl. Is it a lock for "demo" licences or can it be changed in some way ? This DeviceSet name is too way long with spaces inside, not easy to handle with string parsing... Cheers !

Post by struccc on HTML5 Controls - string(>80) values ^{CODESYS Forge talk (Post)}
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hello guys, I have the following problem with the Codesys visualization (4.6.0) and Codesys V3.5.20.20. I would like to use my own HTML5 elements for my visualization. To do this, I have to select the option “Support client animations and overlay of native elements” in the visualization manager. But with the selection of this option, the visu has a massive loading delay when changing frame content. This happens even if I have not even added HTML5 elements. However, if this option is deactivated, then changing the content of the frames works without any problems, it loads instantly. I have already tried to change various refresh rates but without success. Have any of you experienced this and been able to fix it?

Hi there! I'm testing out modbus TCP/IP for my home brewery, using Wago PFC200 as both slave and master. I'm using Wago library WagoAppPlcModbus. Holding registers, input registers' and discrete inputs works fine, but when trying to write multiple coils, it doesn't work. Any idea what I'm doing wrong here? Attached is a screenshot of my code. I tried both using bit mapping and without. If I change to FC05, and write only 1 coil at the time, it works fine. But I want to write all at the same time.. Any help is very appreciated :)

Post by gseidel on Beckhoff AS1060 and EL7041 configuration ^{CODESYS Forge talk (Post)}
Hi pmanuele, while I don't have firsthand experience with the EL7041 and the step motor AS1060, there are two things you can check: If you use an external encoder, please make sure you use the alternative device description calles "EL7041 1Ch. Stepper motor output stage (50V, 5A) Rev24 with external Encoder". The SoftMotion driver will set the feedback type automatically, and use the correct object for the actual position (16#6010:21 instead of 16#6010:20) If you have problems with changing the controller mode, I assume to velocity, please make sure you change the PDO mapping so that the actual velocity (16#6020:33) and set velocity (16#7010:33) are mapped by PDO. Hope this helps, Georg

Post by struccc on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I don't exactly recall where (I think some release notes), but I read the information that this multiple application / sub application feature is to be discontinued. Please, correct me, if I'm not right about this I am a bit sad about that - I was using that feature with more or less success. However I understand the reason behind the change: it introduces huge complexity, especially when dealing with multicore and safety support... AS I understand, it's to be replaced with the new virtual plc architecture, and standard ways for synchronizing / sharing data... So, for now the "Add application" context menu item was removed, but behind the scene it is still supported... Hint: if you still want to experiment with it, might try copy-paste things within the PLCLogic tree...

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I got this working using OPC UA. In the logic application I just added a Symbol Configuration. In the HMI application I added a Data Sources Manager and OPC UA Data Source. The one thing I don't like is the way the tags end up being named in the HMI application. In the logic application I have a program named PLC_PRG. It has a variable named testDINT. In the logic application the name I get for this variable is DeviceSet.CODESYS_Control_Win_V3_x64.Resources.Logic.Programs.PLC_PRG.testDINT. This is very long and looks like it could change if I used this on a different device type. Any ideas how I could get this name shortened down to just PLC_PRG.testDINT like it is on the Logic application?

Post by ameba on PersistentVars and Webvisu Element ^{CODESYS Forge talk (Post)}
hello everyone I would like to try to better understand how persistent variables work. I created some boolean variables in the PersistentVars section initialized to the value TRUE. I have tied these boolean variables to toggle switches placed inside the HMI interface pages. Once the PLC program is started, the lever selectors, if operated, change their state, at least at a graphical level, but the persistent variables do not undergo any variation. Initially the above variables were declared as simple global variables, in this case the operation with the levers was correct; I then tried to transform them into persistent ones with the aim of using them as "settings saver" Thank you for support Bye

Post by timvh on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Which device do you use? Does this have persistent memory (e.g. NVRAM) available? Maybe first ask your PLC vendor about the possibilities and how they advice to use persistent variables? If you have no NVRAM available, CODESYS will store the variables in a file when the device gracefully shuts down. But on an abrupt power failure, this is not possible. If you have no NVRAM and you want to use persistent variables, then consider using a UPS. In this case when the power is lost, the UPS can keep the power on the PLC which then can gracefully shut down. Alternatively use the Persistence Manager to store the variable values in a file e.g. only on change. See: https://content.helpme-codesys.com/en/CODESYS%20Application%20Composer/ac_pm_overview.html

you are able to do this all in one screen. It is possible to set the rights of every element to visible but not editable for the user "none". so everyone is able to see this elements, but can't do any changes. At the login button you set the rights to editable for the user "none" to be able to go to the login. Every element that should be hidden before logging in, set the rights visible and editable only for "higher" users. Hint: to change rights you are able to select more then one element and edit rights for all at the same time. Saves a lot of time! Good luck!
