Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hello, We have a problem with CodeSys on a raspbery pi with an ADS1015 analog to I2C module. It can't find the I2C device on the i2c bus, it says No I2C Driver Found. When we use the RPI terminal we can find the I2C device and read it out. The i2c-1 bus is also accessible from codesys. The device address of the Analog to I2C module is 0x48. Can someone have a look what the problem is? i submitted the screenshots in the attachments. i also include the device description and library.

Post by madskaizer on ModbusTCP Slave Device, maximum uiClientConnections? ^{CODESYS Forge talk (Post)}
I got a Wago PFC200V2, running Codesys 3.5.16.40, 100ms scan cycle, consumes about 20ms. It will randomly crash the runtime every 10 minutes to a few hours. We suspect an overloaded ModbusTCP Slave Device, as this is work done by a 3rd party contractor, but we can not find anything in the help files or documentation, that mentions a hard limit on maximum number of clients connections. This PLC currently has 44 client connections to the Slave Device and 29 slaves configured for its own Master Device. This topic metnions a hard limit of maximum 16 connections, but where is this written? https://forge.codesys.com/forge/talk/Engineering/thread/bd95b9d6d2/

Post by timvh on Dynamically enabling/disabling Modbus slave devices in runtime (performance issue with timeouts) ^{CODESYS Forge talk (Post)}
As far as I remember, the Reconfigure functionality doesn't work for Modbus devices. But... Each Modbus device in your device tree has a name. You can set the property "Enable" of this device to FALSE to stop communicating with it. So if one of your Modbus Slave devices name is "MbSlave1" in the device tree, then in your code you can set the Enable to FALSE to let it stop communicating: MbSlave1.Enable := FALSE; Please let us know if this worked on your controller with your application and your CODESYS version. Alternatively you could use the ModbusFB library. See: https://forge.codesys.com/prj/codesys-example/modbus/home/Home/

Post by wmoon on Licensing info not available. ^{CODESYS Forge talk (Post)}
Hello, I bought some licenses from CODESYS store. I am trying to install licenses into my device(CODESYS Control for Linux ARM64 SL). But I have a trouble with it. I did it in the following order. Tool -> License Manager Selected Device and Next... Selected Soft container and Next... Select the device and Ok.. And then I always show a message "Licensing info not available. There is no dongle attached to the device." And I tried to click "Install Licenses" button. I saw the message "The value cannot be NULL. Parameter name : continerToLicenses" Could you let me know what I've missed or what I've got wrong?

Post by damian177 on CM4S GPIO's in Codesys ^{CODESYS Forge talk (Post)}
Hi, I am running my application on device based on Compute Module 4S (Cortex-A72 (ARMv8) 64-bit ). On this device I installed RPi Runtime in 4.11.0.0 version. In my project I use device: Codesys Control for Raspberry Pi 64SL and my project works, but I actually do not have acces to all GPIO's , because GPIOs Compute Module is available only in 3.5.16.0 version and it doesn't work. Properly work GPIOs B+/Pi2 but using this device I do not have acces to all GPIO's in CM4S. Anyone of can tell me how add GPIOs Compute Module 4.11.0.0 to my project ?

Post by valenting on Runtime not working on raspberry pi Bullseye ^{CODESYS Forge talk (Post)}
Hello I have a problem with Codesys on Raspberry pi with Bullseye The device is not recognized as a Raspberry pi, as I get this error : ooops... this runtime was built for RASPBERRYPI. Hardware version or firmware version not supported! (-18, 0x00000BB8, 0xFFFFFFFB) I'm running Codesys on a compute module 4S with Raspbian GNU/Linux 11 (bullseye), my kernel version is Linux 5.10.90-v7l+ Codesys version is the latest, released last week (4.11.0.0, CODESYS Control V3.5.19.61 for ARM-32Bit - build Feb 22 2024) I know it works on the same device if I use Raspbian 10 (Buster) with Linux 5.4.81-v7l+ kernel, but for some other reasons I have to use Bullseye. What can I do ?
