Post by wbj0t on Raspberry Pi CM4. CoDeSyS files corrupted after hard reset. ^{CODESYS Forge talk (Post)}
Hello everyone. Raspberry Pi CM4 after some 1 week of work was hard reset mannualy several times and after these hard resets User Management file was missed (when click login button, enter login/password, error: User Management File missed). Also programm can not open file via SysFile library, but this file exists and size of him is 0 bytes, but must be more any way (I keep some kind of archive via this lib). What happens, how files corrupted? Where do I need try to find this error of the codesys or system whole? In the log files of codesys nothing interesting about this happens. Thanks for reading Is this enough hold PlcLogic and SysFileMap.cfg as reserve copy in another place for restoring the programm? And how automate restoring actions if programm files corrupted?

My experience is that opening pdf file is very dependent on which browser is used. I have tried a couple of them and only Mozilla Firefox has opened file correctly in same screen. All other browsers face some issues. Therefor I had to flip my pdf to txt which has not been nice solution.

Post by dkugler on User management ^{CODESYS Forge talk (Post)}
If the PLC is equieped with a USB socket it's possible to copy the user management file via IEC code to a USB stick and restore it at the new plc. The file is located there: /PlcLogic/visu/app_visuusermgmtdb.csv I use this to reset the user management to default in case of the customer has changed passwords and lost it.

It's a bit confusing, the two RPI is the same (board, OS, runtime, programing with Codesys V3.5 SP20 P2) but the one has a codesyscontrol.cfg file and the other has a codesyscontrol_user.cfg file. Shouldn't be the same? And because I over Codesys 3.5 SP 12 this would be the '_user.cfg' for both. Attached...

Post by albzen on EtherCat Slaves diagnosis ^{CODESYS Forge talk (Post)}
Hello everybody, I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus with many devices. The bus has some communication fault but I don't know how understand which is the device or the cable that has the trouble. To understand the cause of the problem I would like to read the WKC (Working counter) of the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of the counter is disabled. Attached there is an extract of the Ethercat document. Can anyone give me some advice about how and with function can I read it. Thank you in advance!

Post by sigurdrb on Codesys and error messages, warnings exceptions etc. ^{CODESYS Forge talk (Post)}
Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

Post by ellcap on Symbol Configuration, I'm doing it wrong ^{CODESYS Forge talk (Post)}
if you're here because you are making the same mistake as me, I just resolved it. I mistakenly thought I didn't need to write the word attribute in the column labeled attribute. changed this 'symbol' := 'read' to this attribute 'symbol' := 'read' The last two in this clip are still wrong: I recongize this is probably a big "duh". That's ok. I like to fail out loud in hopes it helps someone else from looking silly.

Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

Post by leandroct on Error reading files after runtime update from 4.0.0.0 to 4.8.0.0 ^{CODESYS Forge talk (Post)}
Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled. See following issue: CDS-81506 - CODESYS Control SysFile system file access vulnerability. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 Here is the official release-note: [[COMPATIBILITY_INFORMATION]] With the activation of ForceIecFilePath the file access from IEC is now restricted to the configured paths only (file sandbox)! [SysFile] ForceIecFilePath=1 (new default) The standard path is the current directory, the PlcLogic subfolder or a configured path. Every file access outside of this path is configured via PlaceholderFilePath, for example access to temporary files or removable media: [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ PlaceholderFilePath.2=/media/usb, $USB$ PlaceholderFilePath.2.Volatile=1 For more information see our tutorial FilePath & Placeholders. To restore the old behavior ForceIecFilePath may be configured as follows: [SysFile] ForceIecFilePath=0 BUT WE HIGHLY RECOMMEND TO LEAVE THIS SETTING AT ITS NEW DEFAULT VALUE! "
