Post by rcanfield on Code Coverage and Test Manager ^{CODESYS Forge talk (Post)}
I am exploring the possibility of measuring test coverage using the Test Manager and Profiler tools. It appears there are some significant limitations. Has anyone been successful trying to use these tools? Here are my observed limitations. Am I misunderstanding anything? * Profiler only works for one "run cycle". Even warm resets will clear the coverage calculations. Thus, all tests would have to manually reset values when complete to prevent contamination to other tests. * It is not possible to see which statements were/weren't executed. One would have to use the flow control tool which cannot be used in conjunction with the Profiler, and must be viewed in realtime. * The profiler control cannot be automated and therefore must be executed through a manual procedure. Thank you!

Post by lorenzo-pisoni on SysProcessExecuteCommand ^{CODESYS Forge talk (Post)}
Hello, I'm encountering an issue with the Sysprocess library while attempting to execute commands to transfer a file from a NAS to my PLC. Currently, I'm trying to test a simple "reboot" command, but it doesn't work as demonstrated in this video: https://youtu.be/77c7Af5xRhE?si=uFZdB6fTNQitzWMQ. I'm using CODESYS V3.5 SP18 Patch 4 (3.5.18.40). From other sources, I've learned that to enable the PLC to execute commands, I need to add the following line to the file CODESYSControl_User.txt: [SysProcess] Command=AllowAll However, the issue I'm facing is that this file doesn't exist on my CPU. I have full SSH access and can see all files, but only CODESYSControl.txt is present. Adding the command to CODESYSControl.txt hasn't resolved the problem.

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Post by mubeta on Reset problem with CMZ SD/SVM drive ^{CODESYS Forge talk (Post)}
In a recent project with SoftMotion 4.15.0.0, where I integrated two SD drives from CMZ (from catalogue EDS and not imported), on CANopen bus, I found that the SoftMotion MC_Reset function does not reset the drive faults. Even if the drive is in fault, either on the device or on the drive at the CoDeSys level, the function does not reset, instead reporting the error code: no error to reset. Finally, I had to connect the reset bit of the ControlWord directly to a tag in my program. Something I never had to do on other drives: Lexium, etc. all reset simply with MC_Reset.

Post by dawidr on Best practices for querying multiple MODBUS devices ^{CODESYS Forge talk (Post)}
Hi! What are the best practices for querying multiple Modbus devices? Single PRG or maybe multiple PRG (so basically multiple thread) per each Modbus device. In my current implementation I'm using single PRG and I'm utilizing FbMbMasterMultiQuerySerial and WagoAppPlcModbus.FbDigitalTwinMbSlaveDevice in eCockpit with PFC200. I've the timer with 2 seconds delay there and it was working fine for single device. But now I have three Modbus devices and for two of them I need to run 2/3 queries to get data from all registers. I noticed that the delays for getting the data from the Modbus devices is much bigger right now.

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

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 trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by damian177 on Problem with downloading OPC UA tags by Data Source Manager ^{CODESYS Forge talk (Post)}
Hi, In Codesys V3.5 SP20, using Data Source Manager I am trying to connect to the OPC UA server and receive tags from it. The connection is ok, but the Codesys have a problem with downloading Tags group. The window (downloadingTags.jpg in attachement) never stop. After waiting for a while, I disconnect the connection and only the Server group remains downloaded, with OPC UA server diagnostic data (and this is read in Codesys). Of course, I tried connected via another OPC UA client : UaExpert , and everything works as it should, all tags are downloaded (Uaexpert.jpg screen). Has anyone on the forum encountered the OPC UA client configuration in Codesys? Is it possible to manually request the appropriate tags from the OPC server for reading in Codesys?

Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

I ordered a cheap managed switch and tested it as soon as I received the switch. It works great! I even went a bit further. As you can see in the screenshot, I created 2 Codesys containers. Each one having 2 fieldbuses. The first one has EtherCAT and EtherNet/IP and the second one has EtherCAT and Modbus/TCP. All going through the same ethernet port from the PC to the switch. The switch splits it up into 4 different networks. The hardest part was to figure out how to configure the switch. @eschwellinger, thank you very much.

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?

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Hi All, I use the analysis page in automation server to capture historical trends from my PLC - i only sample one point per hour but it does the job (for now) One issue I have is I often log on to analysis page to find the system has stopped recording trends from my PLC. To fix this, I need to choose "state information" in the "List view" under PLC and click "Reconnect" When I do this I see my variables listed under "parameters" under "PLC Details" start updating again and the trend in Data analyzer continues to update. My Question, Why do I need to manually reconnect? Is there a way to get automation server to automatically reconnect to the PLC so I continue to capture data from the PLC? Regards, Trent

Post by timvh on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
It seems you have 2 network interfaces. Did you try eth1? Did you already configure the IP address for this interface in Linux? If yes, then maybe undo this. - or only set eth0 in the Nic configuration without anything else (so no IP address, because this is already set in Linux). For more information about the Nic settings, see (probably already read it?): https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_obj_deploy_control_sl_configuration.html PS, if you only want to run CODESYS Control SL, you don't necessarily need the Virtual PLC variant. You could also install and run the CODESYS Control SL Runtime in the Host operating system. This way you should also be able to access the serial port and directly access all ethernet ports. Maybe this is easier?

Post by struccc on Problem Update new version Master ethercat ^{CODESYS Forge talk (Post)}
Hi, I had some issues as well migrating to the new version. What I have learnt: - Have to check all the libraries in the library manager, if they are the proper versions. - Some other parts of the application, maybe an old library referenced by another one can keep the old Ethercat libraries.... Use the "Placeholders" function on the library manager - See if there is a new version available of the slave "devices". Might just have to update them ... I had problems moving from 4.7 to with 4.8, especially with the 2nd adapter for redundancy - some devices failed to initialize properly.... So I have just downgraded those libraries now. P.

Ok, with debug you suppress the errors, but that doesn't help you any further. You can find information about the missing drivers here https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/ and here https://github.com/stefandreyer/I2C-Multiplex I'll have to have another look at which library you need. But you can easily find out. Create a completely empty project and insert the TCA9548. You don't need the board. Then look in the library and resolve all conflicts If you can compile the project without errors, delete the TCA9548 and insert the ADS1115. The driver should then also run. Small bonus: with the TCA9548 you can expand your network as you wish and use identical sensors multiple times
