Hi everyone, I’m new to CODESYS and Wago devices, and I’m trying to set up Modbus RTU communication. I have a Wago PFC200 (8110) and a 750-653 RS485 module, and I want to read data from an energy meter using Modbus RTU. Thanks in advance for your help!

Post by yannickasselin on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have been running Codesys IDE in VirtualBox on a Linux Mint host for many many years without issues. I use it every day and it works great. I wouldn't mess around with wine. Would probably just be a waste of time. Codesys Go might be the future of PLC programming on Linux! Can't wait to test it.

Post by davidmic on Struct Literal ^{CODESYS Forge talk (Post)}
Hi all I want to pass a struct into a function without declaring the struct in a VAR/END_VAR. Is this possible? I think this would be called a struct literal It would look something like this someFB.write(structArgument := MyStruct#(a := 1, b := 1.2), otherArgument := TRUE); With this struct declaration TYPE MyStruct : STRUCT a : INT; b : REAL; END_STRUCT END_TYPE

Hello everyone. I am using Codesys and saw in a YouTube video on the Codesys channel (https://www.youtube.com/watch?v=y_l2siXY7dA) that you can create frames and move them with the mouse. However, the video does not show how to do this. Can someone please explain it to me? Thank you very much.

Thank you for your answer! I know that 0 will be the end of the string. I checked it. There is no 0 in array of bytes. I made screenshots. There is array of bytes, aborted string and the result of my test via online converter.

Hi jbu0105, which error doe you get, exactly? Is it error 11008, SMC_MOVE_INVALID_DYNAMICS? (It might help if you check the "Log" tab in the PLC device and copy the exact error.) Please double-check whether the inputs Velocity, Acceleration, Deceleration, and Jerk of MC_MoveCircularAbsolute have correct (positive) values. Best regards, Georg

Nachdem ich einige Zeit unbehelligt arbeiten konnte, bin ich wieder ausgesperrt, Deinstallieren und Neuinstallation der Nachfolgeversion (SP21) hat nichts gebracht und der Trick, der unter SP18 funktioniert ist mittlerweile verbaut (wie bereits geschrieben). Gibt es evtl. in der Registry einen Ort, an dem ich etwas löschen muss / modifizieren kann?

the Answer is easy, you don't reapecting the codesys-behaviour and pre-request on a dll/so like you like to create. codesys won't load it about the fact that the dll isn't registered in codesys. check this page for more informations: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_extension_extension_sdk.html

Hello, Working in 3.5 SP11 32 bit and using the 3S CANopenSafety Slave 3.5.11.0 library on an IFM CR711S. The 3SCSSD.CANOpenDevicesSIL2 function block keeps throwing "UNSAFESTACK_NOT_OPERATIONAL" Additionally, the Status of the device gives "There was an error accessing an I/O parameter". Any ideas on where my issues may lay? I have not found any good documentation that would explain the issue.

da kenne ich einige Ursachen: - Antimalwareserviceexecutable - Projekt liegt am Netzlaufwerk - Projekt liegt in OneDrive - Die Festplatte ist voll - Arbeitsspeicher ist voll - Netzwerkanbinding ist mangelhaft - Windows-Update ist fehlerhaft oder es steht noch ein Neustart aus Das sind so die am häufigsten auftrettenden Probleme im Zusammenhang mit dem verhalten. Ab und an hilft auch eine Neuinstallation von Codesys

Post by imdatatas on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Hi, You can give a try it by adding "Codesys.exe" in the "Exclusions > Process" section of the Windows Security Center or your antivirus program. I hope it works for your situation. Antivirus programs check many things during both the installation or startup of an application, and may be slow down or block some functions. Regards Imdat

This is a homing routine which is controlled by setting mode of operation and started by setting a bit in the control word. If MC_Home is not usable for this homing method then I need to implement the same functionality. But how?

It seems that the hmi sl license only works with windows. If i'm happy using web visu, rather than target visu, is possible to use remote opc-ua remote alarms without the hmi sl? Maybe it can be included in a different license that works on Linux? thanks

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?

Hi, which CODESYS Version are you using exactly? Either update to 3.5.21.x if you are on 3.5.20.x if not - add a more secure pw. Seems that on adding the login credentials it is mandatory in 4.16.0.0 -to have complianct to password policy seems a bug that the message not occure.

ich meine mich zu erinnern, dass ich schon FB's hatte, die Fehlermeldungen mit löschen des Enable/Execute Bits abgelöscht haben. Dann würde bei dir sobald das Error Bit gesetzt wird, nichts mehr drin stehen. Vielleicht wäre es ein Versuch wert, den String vor dem zurücksetzen des Execute in eine Variable zu speichern, ob dann was drin steht und danach erst ablöschen?

Post by eschwellinger on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.

Yes, you are right. I think the help is pretty clear: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_library_development.html It helps you to find errors in the source code of your library if you want to create a library which is using pointers and you want to use your library on 32 and/or 64 bit platforms.
