Post by food on Beaglebone Black OPC-UA Server ^{CODESYS Forge talk (Post)}
Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.

Post by arcadium on TargetVisu element stacking on top of each other ^{CODESYS Forge talk (Post)}
Hello, I'm new here so if I do something wrong please bare with me. I am using raspberry pi touchscreen made by comfile (CPi-C070WR4C). I also have a window 11 pc where I would like to have a second visualisation, but when I run a TargetVisu with it, all elements of the visualisation end up in the top left corner stacked on top of each other. I have same results running targetVisu on my laptop. Maybe someone had same issues and know the solution? Simas

Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Post by jeroen on Ramp function ^{CODESYS Forge talk (Post)}
Hi, Found a nice ramp function in the OSCAT lib (FT_RMP), but is there a nice way to 'set' the output to the current input as form of a reset. The reason for this, is that I want to set up a ramp for a pressure control input that should have x Bar/sec linear rise input. The only option (or code it by hand) I found is this OSCAT FB. Any other options? Just need to increase a value by x Bar/sec from let's say 250Bar (as start) to end 1500Bar. The Oscat ramp will always start at 0 when enable is off (FT_RMP.Rmp := FALSE)

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

Post by niallel on Continuous MC_PositionProfile ^{CODESYS Forge talk (Post)}
Hi, Is it possible to have a MC_PositionProfile that runs continuously again and again without stopping the motor and starting again. I have a profile that contains about 50 steps that I want to repeat. At the end of each run the motor comes to a stop before the next one starts. My code checks for Done, then resets the Execute to False before setting Execute to True to run again, and I think this is causing the motor to go to standstill before starting again. There doesn't seem to be a BufferMode option like with MC_MoveAbsolute. Is it possible to do this? Many thanks,

Hi there, I'm testing out MQTT from my Wago PLC using JSON object. I have managed to publish this {"Temperature":15.6,"Setpoint":38.0} to my broker. Now I', trying to subscribe to the same message. The result is this: '{"Temperature":15.6,"Setpoint":38.0}95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' First, why do I see 95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' at the end of the message? Second, how Can i sort out this data to use it in my program? I followed a youtube tutorial which gave me the attached result, which works. But I need some other smart way of doing this when the object gets even more data in it. Any help is very appreciated :)

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Post by paulpotat on Exclude traces when searching with ctrl+F ^{CODESYS Forge talk (Post)}
Hello, I was wondering if there is a way in codesys to exclude the traces from the search when using the "ctrl+F" window ? That would be nice to improve the search functionnality when looking for a specific variable. Sometimes when I iterate through all occurences with the "find next" button, it opens the trace configuration window. I would expect to be able to close it and go to the next occurence with the "find next" button, but after closing the trace configuration window the search says it has reached the end of the scope (even if in reality there are other occurences of the variable elsewhere). I tried to enable / disable the "search up" checkbox but it's not changing anything. I hope somebody have insight on this, BR

Post by timvh on Visuutils FbOpenDialog(Extended) not open Dialog from POUs ^{CODESYS Forge talk (Post)}
I had a similar situation recently where this didn't work, but read to the end to see the solution. The reason is that CODESYS only downloads visualisations (dialogs) if they are part of the project or linked to the project. In your case the dialog is not loaded onto the controller. But the solution is pretty simple: Double click on the Visualization Manager in your application. Select the Tab "Visualizations". Here you can see that your dialog is not "checked". Do this manually and load your project on the controller. Then your code should be able to open the dialog, because now it exists on the controller.

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

Post by toby on Ethernet/IP communication with Omron NX1P2 ^{CODESYS Forge talk (Post)}
Hey guys, I'm very much a noob with networking, it's my achillies heel, and this is my first networking project using Ethernet/IP. Any help offered is GREATLY appreciated. I'm trying to network a Codesys Project with an Omron NX1P2 PLC. I'm using EIP due to hardware restrains. I've added the fieldbus, EIP scanner (as the master), and made a Network Variable List. On the Sysmac Studio end, I've made the variables and set them to network inputs/outputs, registered them in EIP settings, but when I try to set the target device (the Codesys project), I suspect I need to import an EDS file for the EIP mapping. Back in the Codesys project, I'm not sure how to: - Make an EDS file to share with Sysmac Studio - How to link the target device (Omron PLC) to the EIP fieldbus - How to map the inputs from the Omron PLC. Im sorry for my very open request for help, i'm kind of lost looking through the various forums/video/tutorials as many of them dont match what im trying to do. Any help, or sample programs would be so so greatly appreciated. If you need any further clarifications, please feel free to ask. Thanks in advance, Toby

Post by dominggus on when going online, stuck on "Syncing file "visuelemsdatetime.tl_datetime.txt" ^{CODESYS Forge talk (Post)}
Hi, We are currently using a Raspberry Pi 4 CM4 module in a EdgeBox RPI 200 - Industrial Edge Controller running the latest CODESYS Runtime Package 4.11.0.0. On the PC (actually an Intel Macbook Pro running Windows 10 in Parallels) we run CODESYS V3.5.19.50. Yesterday end of day when I was about to logoff and head home, I wanted to send the latest build to the Raspberry I clicked the Login button to compile a new version and then sync the application and all the files, it get's stuck on the last file to sync (see attached screenshot). This takes eternally, although sometimes, when I use my SFTP client (Cyberduck) and go into the raspberry and refresh the directory /var/opt/codesys/PlcLogic/visu/, or when I open the actual file visuelemsdatetime.tl_datetime.txt, it gets un-stuck (forcing a refresh, which might fix the syncing issue) and CODESYS continues and I can click the Start button to start the application. But this SFTP force refresh trick does not always help either... What could be the issue here? network connectivity? Can someone please help me out?

Post by mtho on JSON Utilities - JSON file written with invalid structure ^{CODESYS Forge talk (Post)}
I'm using the JSON Utilities SL library to write configurations in my program to a file. I'm generating the JSON data using the builder function block and all appears to work correctly. When I write the jsondata to file, I'm finding that some of the JSON elements are not being written in the right location in the file. Rather than writing they keys under the parent object, they get written outside the root JSON object at the end of the file. If I then try to read the file back into the program, I get an invalid_structure error. I don't get any errors when populating the JSON data or when writing the file. I attached an example of the JSON writer output. The problems begin with key P200. Each P200 should go under MBR1 through MBR3. Among the rest of the keys, they are supposed to be under different parent objects. I am using default values for wsLineBreak and encoding.

I have a project with a Festo CPX-E-CEC-C1-PN PLC (Run-time version 3.5.12.50) that I have been developing on just fine using Codesys V3.5 SP19 Patch 5 (64bit). I am at the stage where I wanted to use the Festo HMI screen, and have added a RemoteTargetVisu object to my application. After adding this object, I am no longer able to log in to the PLC as I get an Unresolved Reference warning for 'USERMGRUSERGETPROPERTY' towards the end of the download process. I was able to find this post (https://forge.codesys.com/forge/talk/Visualization/thread/fc686a6cb2/) where the two possible solutions are to "set the placeholder to emtpy" or update the runtime. Problem is, I don't know how to do either of these things, as I'm still very green in Codesys land. I'd be happy to update the Festo PLC runtime, as that seems like the better option, but have not had any luck in finding a tutorial for this online. If anyone could point me in the right direction I'd appreciate it.

The hole setup is made by 3s. So its a comination of one not two. If Epis decide not to support extra licence whats then the funtion of providing an option with a single license ?? So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Post by rabaggett on Reading Named Pipes in Linux Is there a better way? ^{CODESYS Forge talk (Post)}
I have a Python program that will handle things in my application such as VISA over IP and Telnet control of instruments. I want the main control and HMI in Codesys. My problem is communication between the two. I have looked at several ways to accomplish this, and settled on having the Python program create two named pipes, one to send information to Codesys, and one for Codesys to send information to Python. The information would be packetized with \n for end of packet.. Seems simple. I think the named pipes method should work, but file reading in Codesys using the CAA file library starts to get difficult when the file is never ending, as in this case. Before I spend too much time making something that may be fundamentally flawed I want to ask. Is there a better way? Is there a way to read the file 'one line at a time' which might solve my never ending file problem? Thanks!

Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>

All screenshots are enclosed in MS Word document. NOTE; 4 questions features at the end. Any assistance would be greatly appreciated! Hi everyone, I am still having device logon problem following a fresh install Here are the STEPS I went through following a FRESH CODESYS Win 64 3.5.19.60 install on a different computer. ‘Gateway not configured properly’ when attempting to REFRESH from the Users and Groups. Then did Gateway manage and confirmed it was ok: This message popped out as it was a fresh install: YES then: Initially went with Administrator twice (user & password) but it did not like it. No device is responding to …: Continued by setting a new user Pressed OK and obtained the following message: Stopped and Restarted PLC at that point: Obtained the following: Attempted to login a 2nd time without success. Then I scanned the network to see if matching device can be detected: Only way to get it detected was to remove the tick in the ‘Hide non-matching devices…’ Attempted a WINK but got a return like this one: REFRESH either @ Users and Groups or @ Access Rights returns: Then created user ‘mp’ at Project level ang logged in: Understandably device user mp9876 was not valid for the Project. Device information A few questions comes to my mind following these connection attempts: 1- Gateway not configured properly message pops out because of a non-compatible device ? 2- Why would the device not be compatible ? 3- Any way to make the device compatible ? 4- Any ideas on how to get this connectivity problem to the device solved ?
