Post by eozupek on File Transfer Error 4 ^{CODESYS Forge talk (Post)}
I couldn't exactly solve the file transfer when I wanted to do multiple transfers while the compiler was open in a way that I couldn't understand. Notification from target: runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! * details of the target component that sent this notification: [CmpName=SysExcept, CmpId=0x00000103, ClassID=0X0001008, ErrorID=0X00000001, InfoID= 0X0000000j] I see the warning. I couldn't find out why error code 4 is coming or what kind of measures I need to take to prevent it from coming within the application. Can you help me? regards Emre OZUPEK

Post by tqvist on Gateway Start ^{CODESYS Forge talk (Post)}
Hello, I am trying to connect to my PLC (IFM CR711S) via VPN(EWON COSY). I have been told to use Gateway SP14 or higher. I installed CODESYS 3.5 SP20 Patch4. In the Codesys Installer Software I can sleect "Set Gateway Service" and I do so for CODESYS 3.5 SP20 Patch4. I can start the Gateyay and select About and it shows: "CoDeSys Gateway V3 - x64 Version 3.5.20.40" (see attached) For compatibility reasons I have to run my PLC code in 3.5 SP11 and when I start I can first connect but then somehow the system restarts an older version of the Gateway only displaying: "CoDeSys Gateway V3" (see attached) I guess my question is how to run an old Cocesys Software with a new Gateway?

Post by george32 on TCP Server ^{CODESYS Forge talk (Post)}
Dear people, I would like to create a TCP server in my PLC program. The TCP server needs to communicate with an external device. I have been searching the internet and found that the libraries Syssocket or CAA NetBaseSrv are two possible solutions to create a TCP server. From what I have read, CAA NetBaseSrv is more user-friendly to implement than the Syssocket variant. However, I am still struggling to actually implement this library. Foremost is my little knowledge about creating a TCP server and how to read/understand each function block, especially the outputs of some blocks and the types, e.g. server has an output CAA.Handle, but I cannot find the explanation of CAA.Handle. I tried to find a good document that can help me understand how to implement a TCP server, but I could not find it. Thank you in advance, George

Post by mkintegration on Reading Absolute Encoder Position From Yasakawa Drive ^{CODESYS Forge talk (Post)}
I am looking to read in the absolute position of a yaskawa servo drive Sigma 7 that is using absolute encoder. It looks like yaskawa outputs this across there CN1 I/O connecter and during operation just outputs encoder pulses. But at boot up transmits the Multiturn data position and the Position within one rotation (pulse train) on two different wires. Once the drives are enabled it just uses incremental pulses. Does any one have experience with what IEC blocks to use to read this information in. I attached the Yaskawa Manual section that talks about the format.

Post by bingo on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Suppose you need to switch PLC IP dynamically between 192.168.1.10\192.168.2.10, First, set PLC IP to 192.16.1.10. Create a PGVL with a flag ‘xUseSecondry’ xUseSecondry : bool ; create a function that use socket to update IP: FUNCTION fSwitchIP : bool VAR_INPUT useMainIP:bool; END_VAR --------------------------------CODE------ if useMainIP then SysSockSetIPAddress(‘0’, ‘192.168.1.10’); PGVL.xUseSecondry := 0; else SysSockSetIPAddress(‘0’, ‘192.168.2.10’); PGVL.xUseSecondry := 1; end_if Now, if during execution, you need to switch IP, call the function ‘fSwitchIP()’, Set input to 1 for main IP, 0 for secondary IP. In order to set secondary IP at startup, you can do the following: in your PLC_PRG add a flag: xInit : bool := 1 ; and the code: if xInit then if PGVL.xUseSecondry then fSwitchIP(0); end_if xInit := 0 ; end_if *Alternative way is to use system events.

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks

Post by alberto on ExportPLCopenXML is failing ^{CODESYS Forge talk (Post)}
I'm trying to export my whole project through the option ExportPLCopenXML. It seems working, but when I'm trying to import the xml I have the following error during the importation process: Object reference not set to an instance of an object. It seems a usual issue with this process that affects to the pointer to user classes inside a procedure. I receive this error for two general functions that have this pointer declarations in the VAR_INPUT section. It seems a bug into the export/import process of CodeSYS and I couldn't skip it so far. Anyone could help me? Thanks in advance.

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 ulvis on CFC Pages Cut&Paste is not working at its best ^{CODESYS Forge talk (Post)}
In the CFC page oriendted editor, if I copy some elements consisting of an input connector, some connected logic and an output connector and then paste this on a another page then the pasted elements get inserted with an offset to the right so that the rightmost connector falls outside of the page, in the grey hatched area. So far so good. Then I mark all the elements and try to drag them into the correct placement, collectively. THIS IS NOT POSSIBLE! I only get the "forbidden" icon tooltip. One has to drag & drop the INDIVIDUAL elements to move the elements around. What am I doing wrong?

Hi All, I have problem with ModbusFB.ClientSerial. I'm using 4 different port for Modbus communication. After some time of running program ClientSerial stops to receive data to reply buffer and all request finish with Reply Timeout. The Device sent reply correctly,that it is visible on oscilloscope and it is possible to see that data( reply )are in the device. If the usbtty device is read over external app. then it is possible to see all data which were not taken by ModbusFB.ClientSerial. The stack does not overflow or something , program runs correctly forward and no exceptions or something. The main problem it is that when the error occur than it is not possible to reset port or something or maybe i'm doing it wrong way. please help me with this issue. Thank you for any help in advice Milan

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
Hi, I want to use two OneWireMaster on a Raspberry Pi5. I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0. Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27. Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs. The two masters are 'w1_bus_master1' and 'w1_bus_master2'. In Codesys I've configured to OneWireMasters with the corresponding file paths. But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work. Status is showing "OnewireMaster : Not running" What am I doing wrong? Does Codesys on Raspberry support multiple OneWireMasters? Any help is appreciated.

Post by hclai on Maximum Array Index Issue ^{CODESYS Forge talk (Post)}
I was trying to use a table object in visualization. I want to dynamically show the valid rows in the table. However, it does not work when there is 1 row. i put the maximum array index to 1. it does not show the 1st row. when i change to 2, it show the second row only. my project with older visualization profile version is working perfectly fine. I did some test and realized that i must use a Row Selection variable to change from 0 to 1. With this change of Row selection, then the row 1 will show up.

Post by rer-code on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue. If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input. Best regards

Post by kporter on High-resolution drive with SoftMotion ^{CODESYS Forge talk (Post)}
I'm beta-testing a new EtherCAT drive for a rotary (modulo) axis in a system where the encoder resolution is 81920000 counts per rotation. If I enter this in the SoftMotion Scaling/Mapping tab for "increments <=> motor turns", I get the error below on the Commissioning tab. Is SM unable to handle a high-resolution encoder? The bus cycle is currently set to the default of 4 msec (Control Win V3 x64), although I plan to reduce that to reduce latency, possibly by switching to the realtime (RT) master. Is SoftMotion incompatible with high-resolution encoders? SMC_CGR_INVALID_POSPERIOD Invalid modulo period (<= 0 or greater than half the bus bandwidth)

Post by dkugler on Webvisu Combined Authentication ^{CODESYS Forge talk (Post)}
you are able to do this all in one screen. It is possible to set the rights of every element to visible but not editable for the user "none". so everyone is able to see this elements, but can't do any changes. At the login button you set the rights to editable for the user "none" to be able to go to the login. Every element that should be hidden before logging in, set the rights visible and editable only for "higher" users. Hint: to change rights you are able to select more then one element and edit rights for all at the same time. Saves a lot of time! Good luck!

Post by beavel on Customizing FileOpenSave Dialog and Keypad Integration in Visualization ^{CODESYS Forge talk (Post)}
Hi all, I'm looking to adjust the visualization of the FileOpenSave dialog. Is there a library or visualization file associated with this dialog that can be extracted, customized, and re-imported into the project — similar to how the user management dialogs can be handled? Alternatively, is there a supported way to replace or override the default dialog with a custom one? Also, is it possible to configure the FileOpenSave dialog to use a custom keypad for text input? The rest of the project uses a custom keypad due to readability concerns (the default one is too small), and this inconsistency is now quite noticeable. Any guidance or workarounds would be greatly appreciated. Thanks in advance! @thk @eschwellinger @sheberle

Post by gseidel on Using an Axis of an Axis Group in Torque Conctrol ^{CODESYS Forge talk (Post)}
Hi manuknecht, the axis group currently always writes the axis set torque values. If no dynamic model has been configured for the axis group, then the set torques are written to 0. The solution for your use case is to call SMC_GroupUpdate [0] before you call SMC_SetTorque on the axes. This way, the axis group will write 0 to the set torques in the call to SMC_GroupUpdate(), and SMC_SetTorque then will write the desired set torque. Best regards, Georg [0] https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_GroupUpdate.html
