Hello, Is it possible with the help of a python script on the ctrlX core to access a file on a network drive. Currently we need to use winscp to add the files to the core. The customer doesn't want this because then they have multiple locations to store these files and no longer a overview where everything is stored. Is there already a client to access files on a network drive or is this still in development? Thanks in advance

I've found the cause why my outputs weren't working correctly. The problem started when I added the axis interface template to my project. Somewhere in the demo code in the axis interface it overwrites the datalayer. I don't know exactly where it does this but after I deleted the demo programs from my project I didn't have any problem anymore with my outputs and controlling my axis.

Thanks for the fast response. For adding the io's to my plc program I clicked on Datalayer_Realtime and select realtime data. Then from the ethercat master I selected my drive parameters that I needed and my Output card I also checked if the updated always was enabled but this is disabled. I understand when the output is false that when I use the datalayer the output can be overwritten. But the problem is when I set the output to High in my PLC program the output starts blinking. I attached a video file where you can see the blinking. I only set the variable on one place to true and never to false. The blinking problem also occurs when I try to use the output pin from my drive. So what I see is that something in the datalayer is overwriting my outputs because my plc program sets the value to true and never to false. I made a trace to make sure of this. The end goal is to set the outputs correctly in my plc program and that it won't effect the rest of the system.

I have a problem with setting the outputs of my IO card. The systeem I have is an CtrlX core with a plc program, a ctrlx drive and a beckhoff bus coupler (EK1100) station with an 16 output card (2809). I've succesfully configured the IO configuration and have no errors in my system. If I don't add the output card to my plc program then I can set the output with the help of the datalayer with no problem. But when I add the output card to my plc program then for whatever reason my outputs keeps getting written over by something to 0. After adding the outputs to my plc program it's also not possible anymore to set the outputs with the datalayer. Because the system is not giving me any errors I don't know why and how the system keeps overwriting these outputs. Even if I don't use the outputs in my PLC program they still keep getting overwritten. I want to know what is causing this problem and how to fix it because right now I don't know where to start looking to fix this.

I've fixed the problem. The problem was the ethercat master, for whatever reason it would write my data back to 0. I solved this by deleting the old ethercat master and adding a new ethercat master.
