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.

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

Hello SDO will write to the drive, not the axis, so you need to pass in the ethercat slave: VAR_IN_OUT Axis: IoDrvEthercatLib.ETCSlave; END_VAR Then you can get the address with: Axis.PhysSlaveAddr (as UINT)

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Using SDO, I can read the EtherCAT mappings and offsets from various registers like 0x1c12, 0x1c13, etc. When I obtain registers mapped in the PDOs and various offsets, I could technically access directly to the statusword, controlword, etc., if they are mapped. I have noticed that on IoDrvEthercatLib.ETCSlave_Diag I can find pointers to the input and output buffers. However, although the input buffer can be easily read by referring to what has been obtained from the SDOs, it is not possible to write to the output buffer, as it is overwritten in each cycle by the data from the IOMapping task. Is there a way, knowing an instance of IoDrvEthercatLib.ETCSlave_Diag, to obtain the pointer to the first data in the IOMapping? The offsets are identical to those of the PDOs, but obviously the data is a copy. For me, the cleanest thing would be to access the pointers on IOMapping, for DS402a devices to retrieve the key data and point them to internal references. I need to know this as, having developed our own motion library, I would like to simplify the initial setup by eliminating unnecessary and nonsensical mappings that can lead users to unnecessary errors. In the current version that we have been using for years, we have to map everything manually. I would like to pass only the slave reference to the FB_init constructors and eliminate the mapping.

Post by trusty-squire on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hi, Is there a way to read the homed status from the EtherCAT drive directly? I am currently flagging the homed status on the succesful completion of the MC_Home function block, but I have had false triggers where the drive didn't actually execute the homing procedure but the MC_Home FB is marked as complete without error. I looked at other MC/SMC function blocks but the closest I can find is the "Homing" bit from MC_ReadStatus FB, but this doesn't show if the drive is succesfully homed, only that it's homing. Any guidance is welcome. Thanks!

I need to be able to change (set) the DeviceID of an IO-Link sensor (see DeviceID.png) at runtime. I tried with both ProfinetCommon.PN_PortConfiguration and ProfinetCommon.IOL_PortConfiguration, but I get an error for both when I try to read the port configuration (see PN_PortConfiguration.png). Does one of those FBs is the right one for my purpose? Do I possibly make a mistake when assigning the parameter IOLD_ID/IOLM_ID?

My PLC is WAGO PFC200 Firmware Revision 26. target After updating WAGO_Devices_and_Libraries with newer Firmware 27, CODESYS wants to update all libraries to new versions. I will only add that I did not update the Firmware in the PLC. After compiling the program, I received the following errors: ------ Build started: Application: Device.Application ------- Typify code...

After returning to version 1.5.3.0, the problems disappeared. Probably the version number of this library is responsible for supporting the appropriate Firmware Revision. Can anyone confirm or deny my suspicions?

Hello, I am having trouble figuring out the proper location for my virtual runtime to create a .CSV file. No matter the file location I set, I get error 14 (CANNOT_OPEN_DIRECTORY). I have tried multiple different file paths ('/', '/var/opt/codesysvcontrol/PlcLogic', '/var/opt/codesys/'). I understand that there is only certain places that Codesys can read/write. I am also running this virtual runtime in a Podman container. Does anyone know what the location should be? I attached the archive I was using, a project that tests CSV capability that I borrowed from someone else. Thanks!

Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>
