Hi, I'm experiencing this problem as well. Did the suggested combination resolve your issues in the end? If not, I can stop my efforts rolling back to these versions. I'm trying to get CC for RPi 4.8.0.0 installed on the device, but I can't find it after installing it through the packet manager.

There are examples installed when you install codesys. they are located in C:\Program Files\CODESYS 3.5.19.50\CODESYS\CODESYS SoftMotion\Examples The examples won't be specific to your drive, though you haven't specified the exact drive. After you add the device to the ethercat master you can click on it and set pdo etc

As I see from your logs I think the Timeprovider is not accurate enough in your case. Things to check - at the moment you run it on the same device? (for tesing purpose ok) I would set 127.0.0.0 as IP and set it not really to Core 0 ( many other stuff is there)

Hi Reinier, I'm wondering if you managed to get this FB to work? I was just trying it, and found it not to work, I get an EMCY message in the CodeSys program under the Device Status, but the FB doesn't pick up any EMCY messages from the Bus. Cheers.

Here is what I use to read online the parameter value. proj = projects.primary app = proj.active_application plc = proj.find("Device", True)[0] onlineapp = online.create_online_application(app) onlineapp.login(OnlineChangeOption.Try, True) dev1 = proj.find("DEV1", True)[0] for conn in dev1.connectors: > parms = conn.host_parameters > if len(parms) > 0: > p = parms.by_id(1074855985) > p.read_online_value(2000) ---> error: Gateway not configured properly

I am trying to use Codesys to connect by Modbus RTU to an Arduino UNO, I add the Modbus COM Port but when I try to add the master and the slave I don't have these options, I attach an image of the device manager. I am using Codesys 3.5 SP21.

Post by westcountryewe on ac_persistence not working when creating a Boot Application but works with a Direct Download to the PLC ^{CODESYS Forge talk (Post)}
I am using V3.5 SP18 Patch 5. I have noticed that when I Create a Boot Application from CODESYS, and upload this to my PLC via a USB stick the AC_Persistence does not work and none of my values that are in my PersistenceChannel are retained. However, if I connect direct to my PLC and I perform a direct download of my CODESYS program, my values that are in my PersistenceChannel are retained and work as they should. This makes me wonder if there are files that are missing when a Boot Application is created. I have tried taking a backup of my configuration files after performing a direct download, which gives me the plclog.zip folder, and appears to have the ac_persistence folder present within the file structure, however when I replace the plclogic.zip with the same folder that was created when I created a Boot Application, it still does not work but I wonder whether this is because the ac_persistence folder isn't stored in the correct location for reading. The .app and .crc files are embedded within the plclogic.zip folder, which obviously when uploading need to be standalone files in the root directory of the USB, so the intention there is clearly to extract the .app and .crc files and put them into the correct location within the USB. I wonder if it could be the same for the ac_persistence folder? I have tried moving it to different locations but none have worked. Has anybody else discovered a fix for this? I know the short-term solution is to do a direct download to the PLC but there are some logistical reasons why this isn't neccesarily the best solution for us.

Hi, I am looking for a way to define a local variable that will be multi user independent. This is so several user can connect at the same time select frames independent of each other.
