I believe I have installed the correct device descriptions and library, in an attempt to use the MCP3008 in conjunction with RPI; when project runs the MCP3008 is unable to find the correct driver. Is there anything I'm missing? Very new to this so any help is apprecated!

I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

The codesys application license allows the use of up to 4 fieldbus instances (eg Modbus). I need to use more instances than that. Can I use the Modbus library instead? Does this usage require a license? Similar to other libraries such as CanOpen, Modbus TCP...

Hi, I suppose that you are referring to the error code "SMC_FB_WASNT_CALLED_DURING_MOTION"? Starting of Softmotion version 4.15.0.0 the instance path of the function block that has not been called is logged into the device log. This might help you to identify why it has not been called.

The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.

Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

The other one has mysteriously left. the 2nd and 3rd showed up after I restarted the program. I'm not sure how to take care of them. Please help!

it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

Post by otbeka on CAA File Handling: "Read only" error
CODESYS Forge
talk
(Post)
Hi, On CODESYS V3.5.19.50 I am using the latest 3S File Access library (CAA File & CAA Types) to save and retrieve configuration data from the User Data section of an SD card, via file called config.txt. The application reads the file to memory once upon initialisation, and then the only other operation is overwriting the file with the updated configuration whenever the user changes the settings. An issue is ocurring, seemingly randomly, where the config.txt file, and all surrounding directories, cannot be written to by the unit, returning a READ_ONLY_CAA error upon file open. This sometimes does not clear even after power-cycling the PLC several times, yet checking the file permissions with ls -l shows normal read, write, and execute access. I am wondering if this is caused by the PLC itself or by an issue in my application. I have included my CAA File handler function block (SD_Card_Bin(FB).txt) and any associated types/calls below: TYPE ConfigData : STRUCT Config : ARRAY[0..256] OF STRING(64); NumberOfStrings : UDINT; END_STRUCT END_TYPE TYPE Buffer : STRUCT Data : ARRAY[0..SIZEOF(ConfigData)] OF BYTE; DataLength : UDINT; END_STRUCT END_TYPE A case within my MAIN PRG: mode.WriteConfigDataToFile: VisuElems.CURRENTVISU := 'Screen_Write'; IF xModeHasChanged THEN iErrorCount := 0; iRoute := 0; END_IF CASE iRoute OF 0: inBuffer := ConfigData_To_Buffer(GVL.UnitData); xConfigError := FALSE; xDataConfigured := FALSE; iRoute := 1; 1 : //Read Data from Card SD_Card_Bin.strFileName :=FileName; SD_Card_Bin.iFileOperation := 2; SD_Card_Bin(xExecute :=TRUE, WriteBuffer := inBuffer, xDone =>xDataConfigured, xError=>xConfigError, strErrorCodes=>strError); IF xDataConfigured THEN SD_Card_Bin(xExecute :=FALSE); IF xConfigError THEN iRoute := 32767; ELSE iRoute :=100; END_IF END_IF 100: // The end bCurMode := mode.DisplayProcessVariables; 32767: // Config error iErrorCount := iErrorCount + 1; IF iErrorCount > 2 THEN // Repeats 3 times, if no progress abandons and returns error bCurMode := mode.WriteError; ELSE iRoute := 0; // Try again END_IF END_CASE I'd like to rule out my application as the cause of this bug - help via comments or criticism would be greatly appreciated.

Hello Everyone, Create separate repositories option not working in latest Codesys Installer 2.4.0 (Build 3545). It seems like a useful option regarding install the different versions of Codesys IDE on the same computer and keep in isolation from each other, but unfortunately it didn't work. I hope the Codesys team can fix this issue in the next update. Regards, Imdat

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
