Hi geoweil, have you tried to save changed values to remanent area or using a VAR RETAIN? After restart you have to initialize Counter with last remanent value. Depending on changes per cycle and the possibilitiy of your control unit to write remanent storage. Otherwise you need a buffering system to ensure save backup of last PI_Counter value. May you could read this Thread to get further help: https://forge.codesys.com/forge/talk/Engineering/thread/31e1c8349e/#bf48

Try using a password instead of a public key to log into the controller. I have a video showing how to do this on a default installation of Ubuntu server, it should work the same for Ubuntu Core. https://youtu.be/rj0dOhgnGjs?si=352PmveEP7JXZnO- I sign in to the controller at about 6:40 in the video. I have never tried to remove the public key and revert to signing in using a password, but it looks pretty straightforward https://askubuntu.com/questions/745423/how-to-turn-off-password-less-login-for-ssh

Post by bjarne-pagaard on WebVisu with Runtime Based User Management, Default user (no login) - is it possible? ^{CODESYS Forge talk (Post)}
Hi, With the new Runtime Based User Management, is there any way for WebVisu clients to be logged in to a default user automatically - no login prompt? I would like for the default user to be able to perform normal operation of the machine, without logging in to the WebVisu. This is possible with the Legacy User Management. For the Runtime based user management, there seems to be a default user for the TargetVisu - but not for the WebVisu. -Bjarne

Post by alez on CANOpen SDO to write VISIBLE STRING ^{CODESYS Forge talk (Post)}
Hello, I am experiencing difficulties in configuring a CANopen device by sending SDOs. In particular I am attempting to write an Object Dictionary that has VISIBLE STRING as the Data Type. When I try to configure the sending of an SDO from Codesys to configure this parameter I am not allowed to enter a string value. In my particular case I am trying to change the Manufacturer Device Name ( Index 0x1008 ). Could it be that Codesys doesn't manage these types of variables?

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Hello I am using an OpusA3 with version 3.5 SP17 Patch 3 as part of a project. I had no real problem before I encountered a problem that blocked me. The detection of the OpusA3 from Codesys is done correctly. The gateway is well configured and if I ping the gateway or the OpusA3 I receive the response correctly. The problem is that when I try to connect, the Opus screen freezes and a few moments later Codesys displays an error message ("connection to device closed"). I tried to change PC, to update the runtime, to change OpusA3 but the problem remains the same. I'm a little lost knowing that before it worked without problem. I went back to a previous version of the project (where it worked correctly) but the message still appears. Do you have any clues to solve the problem? Sincerely,
