Post by dandyk on Dynamic Images ^{CODESYS Forge talk (Post)}
Hello, I have very similar problem, but it seems that your solution does not work for me. I am using TwinCAT XAE Shell v3.1.4024.55 and TwinCAT Runtime. Sorry for writing here on codesys forge, but since I found the only relevant topic here and since TwinCAT is almost the same with CODESYS in many applications, I chose to write here. I simply need to dynamically update image in visualization based on camera trigger (I am doing a machine vision application). Camera triggers an image, my program processes it (applies thresholding, draws contours etc...) and saves the processed image in the runtime location (the same one you were mentioning). This was done successfully. I need to make it work at runtime, while the program is executing and I need to refresh the image in the visualization each time camera triggers a new image and program processes it. When I create image element in the visualization and define the bitmap ID variable as STRING which contains the image ID defined in the image pool, then it displays the image in the image pool, but does not work at runtime, while the program is executing. I also used the Bitmap Version. I declared it in Global variable list as integer with initial value of 0 and wrote the variable in the bitmap version in the image element in visualization. Each time new image is saved to the runtime location, I wrote a program to increment Bitmap Version by 1. It increments and the image does not update in the visualization, unfortunately. I think that bitmap version is working correctly and deletes the cached image as it is supposed to, but the Image Pool does not update the image ID with the new image... the path to the image is always the same... only the actual image changes with the same file name. Image Pool is not dynamic and cannot refresh the image in the path to the actual one at runtime. How can I refresh the image ID in the image pool at runtime? Bitmap version only deletes cached image and reloads the image from the image ID, but the image ID has the same image, because image pool won't update at runtime. Do you know any solution to this problem?

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 vformanek on How to access files correctly in Linux ^{CODESYS Forge talk (Post)}
Hello, its still not quite clear to me how to deal with the PLCLogic directory in linux. I have the directory right here: I need to correctly access the files in this folder through CODESYSControl.cfg. Here is my CODESYSControl.cfg where on the first lines there are a few lines: [SysFile] FilePath.1=/etc/, 3S.dat PlcLogicPrefix=1 That means that if I am going to use relative paths its going to go to from the PLCLogic directory right ? For example here: Whitch paths should I use. I cant seem to successfully run any of these aproaches ...

I have a project in Codesys v3.5 sp19 patch2 that contains softmotion virtual axes. I want to simulation the code (softmotion) on the simulated plc on the pc. The controller in the project is a Codesys Softmotion Win V3 x64. I have started up the Codesys Softmotion Win 64 on the pc. However it seems a 3.5 sp14 controller. When trying to download the project, I get a message that target system is different from connected system (3.5.19 vs 3.5.14).

Post by pascaljt on Function block for Ethernet/IP ^{CODESYS Forge talk (Post)}
Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Post by gurke258 on Codesys Safety EtherCAT with Beckhoff ^{CODESYS Forge talk (Post)}
Hello :) We are currently configuring a system with Codesys as SoftPLC on a Linux system and with Beckhoff terminals. I have already gained some experience with Codesys and also with TwinCat incl. TwinCAT Safety. What is new to me now is Codesys in conjunction with Beckhoff safety terminals. We are currently using an EL1918 & EL2904 here. I have been able to integrate both terminals into my project, but I don't know how to interconnect them so that they communicate. That's a bit easier with Twincat ^^ Can any of you help me? I would also prefer a Codesys EtherCAT Safety training or webinar if anyone knows of one. Unfortunately I can't find such an event on the internet.

Goodmorning, I would need to set a control station that can manage a PLC network. In short I need to access to all visu programmed in any PLC of the network (LAN). I was thinking to use a PLC with buttons that call, by mean an IP address, the visu of any PLC. I don't know if it is possible but I saw that there is a RemoteVisuTarget that run CODESYS Control Win V3. Can someone suggest me how to create a remote main control station from a normal PC?

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 jegerjon on Testing of Codesys program ^{CODESYS Forge talk (Post)}
I have a simulation function that toggle xSimActive. I map all IO variables to "IO GVLs" when xSimActive=0. I map IO corresponding SimIO GVL to "IO GVLs" when xSimActive=1. Then I write code for the simulation program that runs when xSimActive=1. Typically increase flow corresponding to pump speed, simulate tankfilling corresponding to flow and so on. I made a FC that require a correct code to activate simulation to avoid unintended activation by service dept. When comissioned remove any possibility to activate simulation. Super when officetesting and supporting service dept. + cheap as it requires no additional equipment, and it is easier to support customer later on in the life cycle as you can test proposed changes without setting up a testlab.

Post by kunz on Responsive Design Example ^{CODESYS Forge talk (Post)}
Hello everyone, I have a problem with the example project Responsive Design Example, which is available here in Codesys Forge. I wanted to try switching the visualization depending on the device type. To do this, I used a smartphone to access it. I can see via breakpoints that the Smartphone visualization is selected, but the visualization of the normal monitor still appears on the smartphone. Could there be a problem with the libraries, or why is the device not assigned the correct visualization page? I dont know how do further debuggin or troubleshooting. Here the page to the example: https://forge.codesys.com/prj/codesys-example/responsive-desi/home/Home/ Thank you very much.

Post by mikek10 on HTTP Client TCP Init Error ^{CODESYS Forge talk (Post)}
Hi, I tried posting in the discussion for the HTTP Client example but perhaps that is not monitored? I have been using http client successfully for approximately 12 months, however in recent weeks I have begun to get TCP_INIT_ERROR when attempting to communicate. The only resolution seems to be power cycling and then the connection begins to work again for a time. I am not aware of any changes to code or libraries between working ok and now. Cold reset does not resolve, only power cycle. It seems the error from NBS.TCP_Client is 6002 which I think is invalid_addr However the address is the same when working and not working?

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by amy123 on Alarm Manager Example Alarm Client doesn't Populate ^{CODESYS Forge talk (Post)}
Hello, I tried to run the example project from https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ However, I can not get the interface for Alarm History 12 Alarm Manager client to populate with any alarms. 'udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClient12, ADR(arritfAlarmsFromHistory12), iMaxCountAlarmsFromHistory12);' when I look at itfAlarmManagerClient12 its always empty. What is confusing is that when I simulate 2 alarms, iCountActiveAlarms 12 has a vlaue of 2, associated with itfAlarmManagerClient12 - so that appears to work. And yet, its useless as the ProcessAlarms Function can't extract anything from the empty array. I dont understand how these arrays are supposed to be populated and why its not working. Any help would be greatly appreciated!

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

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

Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap. Please, if applicable, update these instructions.

Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

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?

Post by gatto on Undertanding Application Based Licenses ^{CODESYS Forge talk (Post)}
Hi, i think you are right. Did you press the key shopping cart? Codesys tells you the license. What I don't appreciate is that i need an additional license for communication. The system reports opc ua but this cheats you. This is communication that also concerns the tag symbols that codesys eth v3 exchanges with an operator panel. Attached is a screenshot of my case where you can see that communication opc ua is cheating you. 512 tags included in the program license are few. So, I had to buy 2 licenses. one for the program and one for communication. I don't like this policy.

Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
If I am understanding what you are saying, then yes that would be your problem. I would create an array of bools on the client side for the transfer and try that. Or if client can't be changed then use words on server and unpack. But I am not sure if you or I are mis interpreting but it sounds a bit jumbled. I don't know what you have control of, but, if you are turning on BITS in the server, you should write to BITS in the client with a Function 15. If you are writing to WORDS in the server, you should write to WORDS in the client with a Function 16.

@imdatatas, thanks for the info, I increased DSP402.uiHomingMinCycles to 10 and have a good feeling that will solve the issue of "false" homings. It's an intermittent issue so I'll report back once it's confirmed. @bruno-roth, also good info. According to my documentation, bit 14 is used to indicate the homed status. I did a test and the bit always stays true after it's been homed once (eg. even if I initiate a new homing procedure then hit the the e-stop mid homing), so I need to take that into consideration, but I can work with that. Thanks!
