Post by leandroct on Error reading files after runtime update from 4.0.0.0 to 4.8.0.0

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! "

You can try this setup: DINTVar := SHL(INT_TO_DINT (Low_Word_INT_Var),16) + INT_TO_DINT(High_Word_INT_Var);

Hi. I'm trying to show in Vijeo Designer a timer countdown. But I want to display the data in hour, minutes and seconds. I tried to change the data by converting in the Machine Expert but not able to succeed. Can you help me to find a solution? Regards, FG

Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.
