<div class="markdown_content"><p>I have exactly the same problem and tried entering “ForceIecFilePath=0” in the file “CODESYSControl.cfg” (<span>[SysFile]</span>). Unfortunately, this was unsuccessful. Can anyone help in the meantime, e.g., with some sample code or with the FAQ that TimvH refers to above (link no longer works)? Many thanks and best regards</p></div>

<div class="markdown_content"><p>Hello, I have the same problem now with 3.5.20 Patch 3. Normally it works if I ad in CODESYSControl.cfg:</p> <p><span>[SysFile]</span><br/> ForceIecFilePath=0 (This told me codesys last time)</p> <p>I try to use the placeholders but without success. Something special is that the Files are not in C:. The Plc Configuration Path is not as usual C:\ProgrammData\CODESYS\CODESYSControlRTEV3\, it's E:\Control.</p></div>

<div class="markdown_content"><p>Hi,<br/> I have the same problem. Some of the libraries I created over time depend on writing fikes to a folders like c:\Temp. I can confirm that proposed solution is not working with 3.5.20 Patch 2.<br/> Can you please specify wich exactly .cfg file needs to be modified and in what way, in order to include c:\Temp in the SysFile path?<br/> Thank you!</p></div>

<div class="markdown_content"><p>Most likely you use a Runtime of SP19 or higher, because starting from this version the default setting is that only access to files in the PLC folder are allowed. This is for security reasons.</p> <p>You can allow the runtime to access files outside of this folder, but you have to modify the CODESYSControl_User.cfg. For the exact file name and it's location, see: <a href="https://faq.codesys.com/display/CDSFAQ/Location+of+the+configuration+file" rel="nofollow">https://faq.codesys.com/display/CDSFAQ/Location+of+the+configuration+file</a><br/> Or ask the vendor of your PLC.</p> <p>One option is to set the IecFilePath, but this limits it to only one folder. More flexible is to use placeholders similar to what you can find in the following link:<br/> <a href="https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager" rel="nofollow">https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager</a></p> <p>An example + more information which I got from the CODESYS support team when I had the same question:<br/> **<br/> <span>[SysFile]</span><br/> PlaceholderFilePath.1=C:\tmp, $TMP$<br/> PlaceholderFilePath.2=C:\IEC, $IEC$<br/> PlaceholderFilePath.3=E:, $USB$<br/> PlaceholderFilePath.3.Volatile=1 <br/> PlaceholderFilePath.3.View=1<br/> PlaceholderFilePath.4=F:, $USB2$<br/> PlaceholderFilePath.4.Volatile=1 <br/> PlaceholderFilePath.4.View=1</p> <p>To make the placeholder visible in the "Device/Files" window, the view attribute must be set.<br/> The volatile attribute is especially important for Linux-like systems, because here newly inserted disks are mounted in directories.</p> <p>You can simply assign placeholders for additional drives in Windows and use them from IEC.</p> <p>The inclined IEC developer then writes<br/> sUsbDir : STRING := '$$USB$$';<br/> sUsbDir2 : STRING := '$$USB2$$';<br/> (with double dollar signs).</p> <p>And the smart CODESYS programmer then uses, with the above configuration, either<br/> sBaseDir : STRING := 'C:\IEC';<br/> or<br/> sBaseDir : STRING := '$$IEC$$';</p> <p>Both will then work.<br/> **</p></div>
