Post by oymyakon on Modbus Lockup ^{CODESYS Forge talk (Post)}
Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Hi all, I’m new to codesys and working on some project. Codesy 3.5 V20 patch 3 Every time I try to use refactor codesys hang and not respond. I was trying to use repair function in installer but this is not helping at all. Wonder if anyone experience this behaviour? Sometimes I have Popup saying : Cannot insert ‘CreateTextFile’ bellow ‘<root>’</root>

Post by eschwellinger on Scan Network on gateway created with Control Sl ^{CODESYS Forge talk (Post)}
it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

Post by phoward131 on Alarm Table Filtering ^{CODESYS Forge talk (Post)}
I actually just found the solution maybe. If anyone else is running into this, go to your Project Settings > Visualization > Advanced (check 'Visible' to see advanced settings) > UNCHECK 'Activate property handling in all element properties.' I am not sure what else unchecking this might affect but it seems to allow the alarm table to be filtered as expected.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

I tried to use C code in the library that I have been developing in the project, but without success. I tried to use the CODESYS Control SL Extension Package to generate XXXdep.h and XXXltf.h, but without success. Do you have a better example of how to generate these files and how to compile them?

Post by totorovic on Project loses 'Download time' information ^{CODESYS Forge talk (Post)}
I continue this topic by myself, I'm very happy with the Codesys support / community ;-) This information (Download time) should be stored in the compileinfo : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_load.html But the file is not text-readable (see attached file) so how to solve if download time is empty?

I am trying to create multiple branches in my project and I keep getting gaps in the ladder logic "wiring". I'm not sure if this is a graphical error or something else but every thing I've tried to do to correct it does not work. Has anyone else run into this or know how to correct it?

Hello everyone, I was just wondering if anybody knows if there's a way to pull the string name of the current visualization without using the current visu variable. I'm working on a project where we don't want web clients to change the current visualization on the HMI of the machine. Thanks!!

1) Based on your first screenshot. Do NOT filter on "Phoenix". Then first select the Ethernet adapter (of CODESYS) and add this to your device. 2) Then to this Ethernet adapter add a Profinet Controller of CODESYS. 3) Then to this Profinet Controller, add your Phoenix Profinet coupler/adapter.

Thank you Pernockham, I am using Windows SoftPLC and the device is CODESYS Control Win V3 x64. In the above attached example, the file is Linux-based. This is an external add-on file in the CODESYS installer (CODESYS Control for PLCnext SL). I am trying to implement it without this add-on file.

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!
