By using the CAA FILE library (FB FILE.Open) (raspberry pi, codesys 3.5.19.0) I always get the error FILE_OPERATION_DENIED The file exist, it has r/w/x access and path is correct... Some idea to fix it?

Hi all, I am also looking for a solution to transfer a csv file from ifm HMI-PLC to some cloud and finally to node-red, for example. Do any of you advise me how to do it? Thanks

An ENI file is needed for a 3rd party software solution that is being used over EtherCAT connection that emulates multiple Slave devices. This one cant be that complex, seen some legacy posts but no answers. Thank you! Bruce

It would be such a simple fix to first check if the file is missing or changed before writing to it, onedrive only has a problem because codesys writes to the file every second no matter the change.

Hi Tobthi, Do you have the eds file of the camera? I usually load first the eds file and then add the device to the Ethernet/IP scanner.

I think that the .err file is the .app file renamed by Codesys, so it is compiled. We met this behaviour one time, it was because the runtime goes in exception due to bad Ethercat cables.

Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

Go in Windows to this location. Right click on this file and go to properties. Is it in Read-only state? Then CODESYS cannot open in Write mode.

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?

For the protocol. What also works is to do the process via ssh (using runtime on linux) sudo /etc/init.d/codesyscontrol stop modify the persistence file values sudo /etc/init.d/codesyscontrol start

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
