Post by mariacugnier on Reading Devices ComState ^{CODESYS Forge talk (Post)}
Does anyone know how to access the ModbusTCPSlave_Diag.ComState without declaring each one by the device name? I attached them to an array but since I may have dozens of devices this is still a bad solution.

Post by canplum on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
Although I have set in /etc/codesyscontrol/CODESYSControl_User.cfg the [SysFile] PlaceholderFilePath.1=/media/pi, $usb$ PlaceholderFilePath.1.View=1 PlaceholderFilePath.1.Volatile=1 I am not able to copy a file to this directory defined by the placeholder. Neither SysProcess.SysProcessExecuteCommand2 nor SysFileCopy nor FileCopy is working. If I try to copy the same file to /home/pi all is working fine. I also can create and open a different file by using SysFileOpen. I don't understand why the system allows to open (create) and write files into that directory but doesn't allow to copy into it. Obviously there is a rights problem with the USB drive. I have already set the permissions to drwxr-xr-x 2 and the user to pi but without any success. With 3.5.16 I never had such an issue. Is there anybody with some hints how to solve that problem? Cheers, canplum

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

If you update all to the newest versions in the project environment and update all devices in the device tree, the errors should gone! Missing the device updates is often causing this problems!

You can write any expression that evaluates to TRUE/FALSE in that property, you can also call a method from the property.

Post by timothyzalusky on Missing Device Descriptions in Repository ^{CODESYS Forge talk (Post)}
For reference this is fixed by installing the new codesys install with a separate repository folder. Completely resolved. If anyone else sees this. I would like to know why the persistent devices repository folder does not properly retain between installs though.

Thx for the hint. It works if I add following line to the .cfg file. PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ Is there a documentation how to modify this config file? Will this be overwritten if I do an update of the CodesysControl Runtime?

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Hi, Is there a solution found for the problem described in first post? Any version above Codesys 3.5 P19 hangs during start up. It makes no difference whether I simply start Codesys or open a project directly. I'm using Windows 10 Home edition. Thanks!
