Post by sivakov on CoDeSys Exception EIP Adapter ^{CODESYS Forge talk (Post)}
Hi, Got same problem, appeared after 4.3.1.0 update. Prabably problem is in performance. I am using virtual machine, so adding one more core and several GB to RAM still not solved, but atleast did system more stable. Try optimise your main program or set less task interval. Regards, I will be your mate in solving this mistery =)

Trying to create a Data Source under Data source manager, but I'm having issues with security. I get "BadUserAcessDenied" I don't know if there is something special I need to do on the Kepware server to make this work or what.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

I want to make an application with a UI for CODESYS Control for Raspberry Pi MC SL which make it possible to switch between dynamin and fixed IP address and to set the IP address. However I do not know whether that is possible?

Post by timvh on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

Post by leon78 on Codesys 3.5 SP17 Patch 2 CheckBounds (POUs for Implicit Checks) ^{CODESYS Forge talk (Post)}
Hello! I use CheckBounds (POUs for Implicit Checks). But I have a problem. I use an array as an VAR_IN_OUT of Function Block. If I try to monitor the array of variable length ([* ]), its does't work. The CheckBounds POU isn't called. If I use the array of fixed lenght ([lower..upper]), the CheckBounds POU is called. Why?

Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.

Hi Sir Kevin. May I know how you came up with this solution. Im a bit confused but I tried to put this. [SysCom] Linux.Devicefile=/dev/ttyRS48 (remember, no 5 at the end!) then set com port in codesys to 6. It also works for me but want to know where did you get this. Thank you.

maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/

Post by acc00 on Redundancy Codesys Runtime, Synchronization ^{CODESYS Forge talk (Post)}
Hi, I’m currently testing the Codesys Redundancy application with 2 Raspberry Pi, with the idea is of using in my project 2 Wago PFC200 and 1 Ethercat Master with 2 Remote IO. After I configure the redundancy, and one Pi is Active and the other is Passive, if I disconnect the Ethernet cable of the Active, the Passive become Standalone, which is good, but the problem is the following: -When I recover the Ethernet connection, both stay Standalone. They will NOT Sync until I do it manually in the Codesys environment. How to make the synchronization automatically? -If both Pi/PLC stays Standalone, who is managing the IO? (Ethercat and Serial) I have done a test with an Modbus Slave, where I am sending a counter that increase every second. And I see that when both PLC are standalone, they both keep an active connection with the Slave, and both write values. This does not seem good, since according to this in my project both PLC would try to control the IO at the same time. Note: The Codesys have an option (greyed out, not possible to select) which says “Auto Sync”. What is the purpose, and why I’m not able to select it? I'm using Codesys Control for Rapsberry Pi 64SL Runtime in my test environment (2xRaspberry Pi 4), with the idea of using Codesys Control PFC 200 Runtime in my project (2xWago PFC200 and 1 Ethercat Master with 2x Wago 750-354 Ethercat Fieldbus Coupler). Using the last Codesys 3.5 version (SP19 PAtch 5). I'd appreciate a lot any help on this questions!

Hi aniket-b, If you save the library as a compiled library you are not able to see the source code. When the end user tries to view inside the object, CODESYS will give a notification that the source code is missing, see attachment. In short if you don't send the source code, it will not show.
