Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Thanks for info... However, I changed the directory to: C:\ProgramData\CODESYS\CODESYSControlWinV3x64\58719825\PlcLogic\Recipes It still displays the content of this folder OK, however still will not write or read files. Is this the PLCLogic area you speak of? I also tried adding this path the the CodesysControl.cfg file. But still can't get it to work. Any additional direction would be appreciated!

Post by trusty-squire on CNC - How to manipulate SMC_GeoInfo objects ^{CODESYS Forge talk (Post)}
I have an application using CNC GCode interpolation, but I need to modify the GCode provided to the PLC based on certain parameters. I am currently attempting to modify the SMC_GeoInfo objects in the SMC_OutQueue using the code below. Note that all the other code is pretty standard and works fine, but when I add the below it errors. PROGRAM TEST VAR fbReadCncFile : SMC_ReadNCFile2; fbCncInterpreter : SMC_NCInterpreter; arrCncInterpreter : ARRAY[1..99] OF SMC_GeoInfo; pGeoInfo: POINTER TO SMC_GeoInfo; giGeoInfo: SMC_GeoInfo; // ... END_VAR // ... Some code here in order to read CNC file using SMC_ReadNCFile2 and provide to SMC_NCInterpreter pGeoInfo := SMC_GetObj(poq:=ADR(fbCncInterpreter.poqDataOut), n:=1); IF pGeoInfo <> 0 THEN giGeoInfo := pGeoInfo^; // Do some manipulation here, then update the queue at the same position MC_SetObj(poq:=ADR(fbCncInterpreter.poqDataOut) , n:=0 , pgi:=ADR(giGeoInfo) ); END_IF It throws an error when I get to the line giGeoInfo := pGeoInfo^; Error: EXCEPTION [AccessViolation] occured: App=[Sim.Device.Application], Task=[PathTask] How do I use SMC_GetObj and access the data? It creates a pointer with the value as shown in the photo, but all the dereferenced values say dereference of invalid pointer.

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge talk (Post)}
For anyone confused with the process visit this link (the bottom section about creating a .pfx file) https://content.helpme-codesys.com/en/LibDevSummary/certificate.html#import-of-client-certificates-with-private-key. I solved this problem by creating a .pfx file and importing it into the security store under 'Own Certificates'(must have SP18 or newer to import .pfx). I used a gitbash shell to enter the openssl command that created the .pfx file. Once you import the file, in your TLS context, set your 'sUseCaseName' to be the same as the name listed in the 'Information' column of your imported certificate. This did it for me

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.

Post by fedex03 on Read Global Variable from an IoT Device ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to the forum, and to programming with CodeSys. I am dealing with IoT device for industry and I should check if a device is able to read/write global variables in an EtherNet/IP Master. Since I do not have an EtherNet/IP PLC, I thought of using CodeSys as a softPLC. I created a program with a set of global variables (GVL) and a task that increments them. I would like to know if I need to enable any options so that the global variables can be read by IoT devices. My device supports Class 2 Class (Explicit Messaging Connection) communication. Thank you in advance for your help.

Post by gatto on CAA File open Problems ^{CODESYS Forge talk (Post)}
Ciao, here same question https://forge.codesys.com/forge/talk/Engineering/thread/2538729618/ in this post https://forge.codesys.com/forge/talk/Engineering/thread/4586a90290/?limit=25#d531 i find : keep in mind that all files which are generated / or read should be exist in the iecfilepath this means: for Windows (Control Win as example) c:\ProgramData\CODESYS\CODESYSControlWinV3x64\268E8ADF\PlcLogic for Linux /var/opt/codesys/PlcLogic I never use codesys on windows but im sure on linux we can manipulate file only inside /var/opt/codesys/Plc Logic. Or you need to modify the file codesyscontrol.cfg for change path permission, but this is another history Buone feste !

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge talk (Post)}
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Sorry, wrong expression. You have a 64bit system, so do I. You can also use the 64bit runtime, but most bib and commands are 32bit and are not properly supported. I had read somewhere that there are problems with I2C. That's why I recommend switching to PI_SL and using the correct gpio.

Post by rmaas on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

Post by hyys12 on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
Hello. I am currently working on a WAGO PLC, where I am trying to wrap my head around how the analog inputs and outputs work in codesys. I have looked far and wide on the internet, for a general introduction to the whole concept, but I have not had any luck with finding anything that helped me understand it better. The whole goal is for me to be able to read an analog input from a temperature sensor, as well as using an analog output, to control a frequency inverter. I know these have nothing to do with each other, but that is all I have on hand right now. I am trying to program this using Ladder Diagram. The only thing is, that every video/guide I have seen/read using LD, just adds a whole lot of function blocks, to do all kinds of stuff they don't explain. My general question is, how would one go ahead and read the analog input, as well as transmit an analog output? Is there some kind of specific function block I would have to use for this, or some great video I can watch, to understand the inner workings. Is it somehow possible to see the values the PLC recieved/sends? Regards.
