it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

Post by timvh on CAN Open Manager - varible of SYNC ^{CODESYS Forge talk (Post)}
You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.

yes i took the library from another forum: https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/, it is made for the ads1115 but the ads1015 is almost the same device with same adresses i only changed the divide value of the analog value, because thats the only difference between the ads1115 and ads1015.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

Okay i will try. I tried already the different settings. The CodeSys version i use, is CodeSys 3.5 SP20 Patch 3. The device which i use is CodeSys Control For Raspberry PI 64 SL version 4.13.0.0. The wiring should be okay because i'm using the Edatec ED-CM4IND-1432-4C(EU).

After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

I took a look at your project. First of all, a Raspbery Pi4 is installed. You must use the GPIOs_A_B(GPIOs B+/Pi2). The error ULINT can't be set to IDINT.... with your project as well. If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’ the error is gone.

I don't have a multiplexer so it very weird that it connects with that multiplexer. If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. I will try again with your libraries

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by martinlithlith on Mux I2C ^{CODESYS Forge talk (Post)}
Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

Post by timvh on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
I'm not sure what you are trying to do, but getting the CurrentUserGroupID like this will not work, because there could be multiple Visualization Clients and each can have a different user that is logged in. Also when you go online with CODESYS and open an Visualization, this is counted as a client. Probably this is the reason you see it changing. What you can to is "iterate" over all clients and then see which user is logged in on which visualization Client. For this you need to add the Visu Utils library to the project and call the FbIterateClients. See https://content.helpme-codesys.com/en/libs/Visu%20Utils/4.4.0.0/VisuUtils/VisuActionUtilities/Function-Blocks/FbIterateClients.html fbClientIteration( xExecute := x_Execute, itfClientFilter := VU.Globals.AllClients, itfIterationCallback := fbIterator, xDone => x_Done, xBusy => x_Busy, xError => x_Error, eError => e_Error); The fbIterator, in the example above, should be an instance of an FB which you have created yourself and this must implement VU.IVisualizationClientIteration. For example: FUNCTION_BLOCK FB_ITERATOR IMPLEMENTS VU.IVisualizationClientIteration Then automatically the corresponding methods will be called. In the HandleClient Method, you will get an interface to the client(s) and then you can get the current user through this interface: itfClient.UserGroupId You can also get the UserName: itfClient.UserName

Post by edepalos on Text list from sd card ^{CODESYS Forge talk (Post)}
Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes... Thank You in advance! Br, Ede

Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

Post by anlebr on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying use the Codesys Communication Manager to set up an Opc ua server with a custom information model. As a start I am using the Boiler model available on Opc foundations github page. I am testing with a Wago CC100 and using Codesys V3.5 SP19 Patch 6. I get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://opcfoundation.org/UA/Boiler/ with a minimal publication date from 15/12/2023 but the device has only a model from 15/09/2021 installed. Probably the information model from 15/09/2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway, both versions are available in the repository. How can I solve this?

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?

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 william-blandon on RecipeManCommands.ReloadRecipes ^{CODESYS Forge talk (Post)}
Hi Dave. Thanks for your answer. I still struggling with this. I have done everything according with the Codesys help even I have looked in detail at the example. I have double checked the recipe manager configuration and the use of all the methods. There are two methods that do not work as expected. I'm using Codesys 3.5.19.20 and recipe management 4.4.0.0 .CreateRecipe just create a recipe in the recipe definition but do not create the file. This have a walk around just giving a .ReadAndSaveRecipe afterwards. .ReloadRecipes do nothing but do not generate any error as well. After calling it I call the .GetRecipeCount and the number is always 0. When I create a new recipe (using the function block methods) then the number changes. Looks like this method is looking to the wrong directory finding nothing. I don't know if there is a missing configuration in the CODESYSControl.cfg file. I'm thinking in a walk around for this but I need to create a strings array with the recipe names as retentive and making all the management when deleting and adding recipes. Have had some one the same problem?

Post by mp9876 on Problem using MeasureFrequence FB ^{CODESYS Forge talk (Post)}
Hi everyone, new at Codesys and PLC programming in general. I am using Codesys Win V3.5 SP20 I would like to measure an encoder's frequency output (obtaining that pulse train from Factory IO) and intended to use the MeasureFrequence FB (Intern/CAA/Utilities/CAA Mathematics/3.5.19.0). As mentioned in the title what I need to measure is low frequency, such as lower than 40hz (a cycle every 25mS) or so; I could even go lower frequency if required as this is for test purposes) therefore I am not expecting problem measuring a low frequency with that FB The library in question appears to be installed as I can retrieve it from the Library Repository. I can also see it from the Device's Library Manager. Problem arises when I am trying to instantiate this particular FB. I go like this: VAR MeasF:MeasureFrequence; END_VAR Please note that as soon as I start typing the "MeasureFrequence", the MeasureFrequence comes out as a viable option in auto-typing; seems to indicate that the FB is recognized somehow. But there is no way I can compile this as it comes back with the following: C0046: Identifier 'MeasureFrequence' not defined. Tried to rename that to ABC instead of MeasF; same issue. Possibly that the library is not properly installed ? Placeholder ? I would greatly appreciate a bit of guidance if possible. Thank you and regards, Mike

Post by mikek10 on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
Hi, I have a project currently in development, it has a number of Ethernet/IP devices (18 adapter devices with Codesys as scanner, another scanner device with codesys as adapter). This has been stable whilst on factory floor for several months (though prior to that I did have some Ethernet/IP issues which were resolved by adjusting RPI rates). Today I tried updating to Ethernet /IP 4.6.0 from 4.5.1, subsequent to this I had 2 exceptions in a 2 hour period, I reverted to 4.5.1 and have had no further exceptions. Note I do have a device (Zebra printer) that frequently times out and reconnects, this does not seem to cause any issues in operation and does not cause any exceptions with 4.5.1. I believe the root cause of this is on the Zebra side, however there does not seem to be any adjustment I can make to prevent the time outs. Information from device log is in screenshot attached.

Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
The probelm arises for the B&R T30 panel after updating Codesys from 3.5.17 to 3.5.19 patch 5. We have to use 3.5.19 for other reasons so we cannot downgrade the version. The scaling problem only exists for the B&R 6PPT30.0702.20F025 panel, the B&R T50 panel and a esa lumia panel work. When we choose a fixed resolution it looks also good, however we also want to support the esa lumia panel with a different resolution. The images show the anisotropic and isotropic option. In the anisotropic option it scales the hight correctly but not the width and in the isotropic option is scales both hight and width false, it also does not start in the top left corner. Does someone have any suggestion why it does not work anymore with the new codesys version and are there workarounds? I added all versions with visualization packages as an image, visuElems is 4.4.0.0.

My topic is more of academic nature, I would like to implement an XOR-operation with four inputs on my own (without the predefined XOR-operator) in a function block diagram (FBD). I have two proposals. One works fine and the other one is just an idea, but I do not know, if it is possible to code it in CODESYS V3.5 SP18 in form of a FBD. Here the one that works: And here an idea, which I have not managed to code it as an FBD: Any ideas? Is the 2nd diagram a correct interpretation of the coding task? And is there a way to implement it in form of an FBD in CODESYS V3.5 SP18? Followup (08-Nov-2024): Also in the current version of CODESYS (V3.5SP20Patch3) I have not managed to connect the existing blocks. In the alternative SPS-IDE PLCnext Engineer it is possible.
