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 ...

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Post by felipemsgarcia on Edge Gateway online, but PLC is not online ^{CODESYS Forge talk (Post)}
Hello, Up until yesterday (2023/11/20) I was able to connect to the PLC remotely with no issues through Edge Gateway. However, today I can see the Edge Gateway online but I can find the PLC even if I do a network scan. Following the same path as janber0206 @ https://forge.codesys.com/forge/talk/automation_server/thread/e78b11d7e9/, I looked into certificates and found that one of the Trusted publisher certificates has expired earlier today (2023/11/21). Please see image. Questions are: Does it affect the connection to the PLC through Edge Gateway? How do I fix it? Thank you very much in advance!

Hello everyone, I want to establish communication between my Arduino and my Raspberry Pi via I²C, but I have no idea how to make it work. However, it should work because there are many examples available, although none of them were programmed using Codesys, but rather using Python. My Raspberry Pi will be the master and is supposed to exchange measurement data such as speed and battery capacity with the slave (Arduino). I would be very grateful if someone could help me with my problem. Here is another link that could be helpful. However, I can't find the mentioned libraries

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 hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

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 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 hyys12 on How to use/create SOTU in LD program ^{CODESYS Forge talk (Post)}
I am trying to make a LD program for an existing installation with a motor. Here an inductive sensor is used to give an input, as a check to verify the conveyor is actually running. Here the plan was to use a TOF timer which gets constantly reset when the sensor input gets detected. The problem is, that if the conveyor is stuck, and the sensor sends a continous signal, the timer will never do what it is supposed to do. Therefor I need some help on how I can convert the input to a pulse, with the help of something like a SOTU. I just cannot find this in codesys anywhere.

Post by xiaolo on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Does Ver. 4.12 support Raspberry Pi 5? I have three issues. The first issue is that Codesys cannot detect the RPI 5 when I want to download the runtime. When assigning the IP Address manually then I can download the runtime. The second issue is that I cannot connect to the RPI to download a program. Sometimes the window pops up and it ask for the user credentials, but it is still not connecting. The third issue is that I cannot connect to an ESP32 configured as a Modbus Slave with a Raspberry Pi 4B. I can connect to the ESP32 via a Radzio! Modbus Master Simulator. I am also missing the function Write Holding Registers in the setup of the slave. Are this known issues and when it will be solved?

Hi everyone, I use Python Script to generate some POU in Codesys V3.5 SP19 and I would like to limit the "Access Control" to them thanks to the Python command. Is there any commands that allow to edit the "Properties... >> Access Control" of the POU? The other possibility is to set the permissions with "Project >> User Management >> Permissions... >> Project objects >> Modify >> ... >> myPOU", but I did not find the related Python commands. Otherwise, is there a global setting that allows to set the permissions by default? For example, Modify = Denied for everyone user by default. Thank you in advance for your help, Nico

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge talk (Post)}
I let this project rest for a while and picked it up last week. I have been in contact with the support from beckhoff and got the information that the terminals were identical (communication wise). As the Log of the Axis (not the drive's log) shows the error when trying to write into the register 0x8012 and set the value for an encoder to a value that is the default - at least according to the manual - I was wondering if it is possible to "not write that value" to skip that part? Or am I misunderstanding the way the library communicates with the drive?

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.

Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

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 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.

Good day I would appreciate it if you can give me some advice on how to fix my "Bus Not Running Error". I am Using Codesys 3.5 SP20 and Codesys Control PLCnext SL V4.12.0.0. Codesys control was installed on the device and I can log into it but it seems that it does not pick up the PLC or the IO attached (Please see attached Image). The Bus Cycle Task of the AXL F 2152 is set to Main Task and the "Always update Variable" is Enabled on each IO Module. My Main Task interval is set to 100ms and Priority is set to 0. I have tried other options and none seem to work. Your response to this issue will be highly appreciated.

Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?
