Bonjour Mucleus, peut-être mettre à jour le Device et recompiler?

Post by fedex03 on Read Global Variable from an IoT Device ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to the forum, and to programming with CodeSys. I am dealing with IoT device for industry and I should check if a device is able to read/write global variables in an EtherNet/IP Master. Since I do not have an EtherNet/IP PLC, I thought of using CodeSys as a softPLC. I created a program with a set of global variables (GVL) and a task that increments them. I would like to know if I need to enable any options so that the global variables can be read by IoT devices. My device supports Class 2 Class (Explicit Messaging Connection) communication. Thank you in advance for your help.

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 joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

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 mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day

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 ?

You need to ask Weintek if they support the licensing. For Softmotion the device should be realtime capable.

Does it mean that the USB dongle has to be inserted all time in order, for the device running in licensed mode?
