Post by mostafa-beshr on implementing continuous movement in Codesys ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on implementing continuous movement in Codesys, but I've run into some trouble. I've tried using ALL SM3 Basic and SML without success. I’m specifically looking for a library that supports continuous updates and can fetch values from a server in real time. Does anyone know of a library or approach that fits these requirements? Any advice or suggestions would be greatly appreciated! i read plcopen documentaion as well as codesys Thank you!

Post by davidbo on RPI can system operation like rm in a shell have an impact on a Task cycle time ^{CODESYS Forge talk (Post)}
CODESYS Control for Raspberry Pi MC SL v4.4.0.0 CANopen_Manager 4.2.0.0 I did not call rm directly from my TASK-i2c, it was trough the attached python script. It is not always a problem happens, but sometimes a rm takes a long time. I reduced the amount of calls to logi2c.py but I don't understand why TASK-i2c sometimes can cause problems for TASK-CAN

Post by jwhaley on C0007 Errors ^{CODESYS Forge talk (Post)}
I ended up figuring it out It wasn't in my code. It kept taking me to 2 of my visualizations but it wasn't going to anything specific. Figured out it was some arrows that I had made to buttons for a mouse click to go to the other visualizations. I removed the text in the assign box but didn't remove the action "change shown Visualization from the list. If I deleted the images all together, the error went away. That's how I thought to go look at that.

Post by mini-developer on Profinet Exor connection drop ^{CODESYS Forge talk (Post)}
Hello, I have a Exor HMI with 2 seperatred ETH interface's. It is Configured as PN Master on ETH interface 1 and the IO's are working, as long as the development PC is connected to the ETH 0 interface. When the PC is disconnected, the PN communication drops and a reconnection is started. I installed the newest device description for Codesys and Firmware for the Panel. The IO Gateway is from Weidmueller What could cause the Problem?

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Thats what I did. The files existed originally, but when I had problems logging in as described I deleted those files (if they in some way had been corrupted causing my problems to login?). After that I have not managed to get the system to re-created these def-files. I manually created the folder structure (from CODESYS file browser) but this has not helped.

Post by warrumungi on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
Hi Thanks, Manuel, for providing this solution and insight. I too had exactly the same problem as you did. While I did implement a custom filter, I'd also like to point out what jinlee mentioned above...I see no reference to VU.PublicVariables.Clients.Current anywhere?? In my case I only needed to show a dialog on a "master" client, not all the clients, so I filtered by IP address to do this.

Post by durallymax on Access Variable Visu Dialog ^{CODESYS Forge talk (Post)}
Is there a way to access the variable in the called dialog? Example: Text Field element with PLC_PRG.myVar as Text variable. OnMouseClick configured to write variable with keypad pop-up. OnValueChanged configured to Execute ST RND(PLC_PRG.myVar,2); Rather than change myVar with each copy of this Text Field, is there a way to access whatever the configured text variable is? Generally try to stay away from ST in visu, but was curious regardless.

Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
When you say it does not work, does nothing happen or do you get an error? I have not used this function in codesys but from my past experience with Modbus I believe the coils need to be contiguous, which may be why yours is failing? Have you tried using Write Registers (16) to do the job? Or is their data in-between you do not want to edit in the transaction?

Post by rmaas on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Hi, The '' characters in Codesys are there only to indicate it is a STRING type. They are not actually added to the string, maybe you are adding them unintentionally in the concat function? You can send your data from Codesys to Hercules to verify... Another option is to send the data as an array of bytes instead of a string, with every byte representing 1 ASCII character. https://www.ascii-code.com/ This way you are 100% sure Codesys is not adding any unwanted characters.

Hi @TimvH, In the meantime, I did some experiments and could find a way to achieve similar result. I made some tests, removing the last card from the array, seeing the change on status. PROGRAM P_IOS_STATUSES VAR devStateInput : DEVICE_STATE; devStateOutput : DEVICE_STATE; devStateEncoder : DEVICE_STATE; END_VAR devStateInput := IoConfig_Globals.EL1819.GetDeviceState(); devStateOutput := IoConfig_Globals.EL2809.GetDeviceState(); devStateEncoder := IoConfig_Globals.EL5151.GetDeviceState(); GVL.bInputCardOK := ( devStateInput = DEVICE_STATE.RUNNING ); GVL.bOutputCardOK := ( devStateOutput = DEVICE_STATE.RUNNING ); GVL.bEncoderCardOK := ( devStateEncoder = DEVICE_STATE.RUNNING ); Many thanks for your quick and extensive reply.

Post by pedrorgd on SFC Exit Action during SFCReset Flag ^{CODESYS Forge talk (Post)}
I have an SFC POU with an SFCReset Flag that I use to restart it from the beginning. It works properly. During an Action Step I set one variable to TRUE and I reset it to FALSE during the Exit Action. My question is if this Exit Action will be activated -and the variable reset to FALSE- if I get out of the active step using the SFCReset Flag.

Post by struccc on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
Are you sure when running as service, it is not reading configuration from C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS... ? Is the SRV user is set for the CODESYS services? 2 ways to fix it: Change the CODESYSControl.cfg in the installation directory (ProgramFiles/CODESYS...). Replace %APPDATA% with something fix. Modify the service configuration in windows service manager to run as a different user (ie bot as Local system account)

Wow! Thanks mr Strucc. Changed to service to run as local acc, and now log works! The service (run from local acc) is using this config: C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg The path you first mentioned (c:\Windows\System32\config\systemprofile\AppData\Roaming) has no CODESYS folder in it (Windows 11 24H2 b26100.3194). Thanks for your help :)

Post by krisj on ScriptEngine POU property Get and Set accessor. ^{CODESYS Forge talk (Post)}
Hey! I am trying to generate a function block with properties from a list with script engine. Codesys/ScriptEngine creates both the Get and the Set accessor. I cannot find a way to delete the Set method/accessor. Anyone encountered the same problem or have a solution for this? for prop_name, prop_type in list: property = pou.create_property(prop_name, prop_type) get = pou.find("Get", recursive=True)[i] get.textual_declaration.replace("") get.textual_implementation.replace(prop_name + " := " + struct_name + "." + prop_name + ";") set = pou.find("Set", recursive=True)[i] set.textual_declaration.replace("") set.textual_implementation.replace("") i += 1

Post by dkugler on Beckhoff EL6652-0010 with Codesys ^{CODESYS Forge talk (Post)}
we use successful for many years the KEB MFI terminal for Profinet, EtherCAT, Ethernet/IP,... You'll need a EtherCAT Coupler as "head" from KEB, Kendrion or Berghof. It's all the same board inside: https://www.kebamerica.com/products/ethercat-bus-coupler/ Or the coupler with 16Di/Do integrated: https://www.kebamerica.com/products/ethercat-digital-io-module/ last year I got a EK1100 with EL6731 Profibus treminal runnig. But it was a lot of reverse engineering and thinkering in Codesys and TwinCAT to be done, to get it up, fulfilling my needs. Good luck!

Post by installwhat on Ethercat and profinet on together ^{CODESYS Forge talk (Post)}
I'm curious about the impact of having profinet and Ethercat (specifically softmotion so frame at start of task?) running together. Since it's advised to access the data from the bus task should have both profinet io and ethercat on the same task? Are there any implications around this one should be aware of especially since the frame at task start is just, so far as I'm aware, an ethercat thing? Thanks

Im Putting alot of my custom functions blocks into a library I have a EthernetIP VSD FB that i would like to get Status from the adaptor. EthernetIP_remote_adaptor.estate is one what i want to get. so anyone know how to point that to my function block? when i use the block i just want to have an input "Drive" that would point to the adaptor. like in softmotion when you just put the axis name in the FB to point the FB to a certain axis. Hope that makes sense, cheers

Update: I still have no idea what was causing my issues, but it went away as soon as I identified that another device on the CAN was generating a Sync message at 16#7F. Changing this to be on 16#80 made the problem go away. I have no idea why this solves the problem and would love to hear from anyone who knows why these two things might be related.

Hi, I'd like to share the list of gateways between different versions (and sandboxes) of Codesys IDE. I refer to the list that is managed in Device > Communication Settings (as described in https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_edt_device_communication_settings.html ) Can I export/import that list? Or is there a file that I can copy from one installation to another one? Thank you GG

Post by imdatatas on Use MC_Home without enabling the drive for homing method 35 ^{CODESYS Forge talk (Post)}
Hello, As far as I know, no matter which home mode is selected, the axis must be in Standstill mode to run MC_Home according to PLCopen state machine. However, if the function you want can already be done from a parameter in the driver of the vendor you are using, you can try to perform the same function by sending the required value to that parameter via communication with the SDO write command.

Post by andrej on Threads and TID created by CODESYSControl Win V3 ^{CODESYS Forge talk (Post)}
Hi all, for a deeper understanding of the Codesys RTE - I created a simple application with 3 IEC tasks (Ta,Tb,Tc) each with different priorities, and different cycle times. The application runs on Windows 10 in the Soft PLC CODESYS Control Win V3. If my understanding is correct, the RTE i.e. the Process CodesysControlService should spawn 3 threads (Th_a,Th_b,Th_c) which are executed with the defined cycle times, the priority of the threads should reflect the priority of the task set in the Codesys IDE. Does somebody have an idea, how I could identify the respective threads in Windows? Kind regards Andrej
