Post by dgrard on Camera RTSP Feed ^{CODESYS Forge} ^talk ^(Post)
Hello Is it possible to view a camera RTSP feed in a visualization? It seems as though the browser element doesn't support this and we are trying to replicate an example using the ActivX element with no luck. We are using the Windows Control Win x64 device with a camera connected via LAN. If it is possible, can you provide some instructions please. Thank you

Post by davidbo on i2c How does CODESYS handle exception or error messages. ^{CODESYS Forge} ^talk ^(Post)
For Raspberry Pi I have made a python script which regularly read a bulk of data over the ic2 from a device. Sometimes I get an Exception an IOError. I assume similar things can happen in CODESYS. So how does CODESYS handle that? Can I get any info about such an event?

Post by florian on Stepper Drive with Ethercat ^{CODESYS Forge} ^talk ^(Post)
Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.

Has anyone figured out a way to use the ethercat bus on a beckhoff CX using codesys running on linux? Using ethercat on the native NICs works fine but I get a "packet could not be sent" error when trying to scan the ethercat bus device. Errors and hardware in attached image.

Post by schnepper on How to delete main action from SFC Step ^{CODESYS Forge} ^talk ^(Post)
I added a main action to an SFC step, and then tried to delete it. There is no delete option in the SFC menu nor in the right click menu of the step. I deleted the action from the device tree, but building results in and error saying the action is not defined. Is there a way to delete a main action?

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge} ^talk ^(Post)
Hello, Basically, everything is clear to me. There's still the issue of a TimeProvider for an external device. This may be a stupid question, but I can't find this package. And of course, the question is, can the RPi machine be an external provider? Has anyone tested such a solution?

Post by mbmik on IoDrvModbusTCP_Diag not defined when using MODBUS ^{CODESYS Forge} ^talk ^(Post)
Hi Im trying to setup a Weidmüller WL2000 to run with MODBUS, to get some data from a server. Codesys V3.5 SP20. The issue is, that whenever i attach an ethernet port and add MODBUS Master und also a Slave, codesys will compile the project, but there always seem to be some remaining errors, which or only visible, when setting the messages window to "Pre-Compiled". I tried a lot of stuff to get rid of these errors, but cant find to seem the reason. New installation of codesys, cleaned project, setup completely empty new project, manually adding libs. Nothing helps. Any help is apreciated. Maybe we are doing something wrong.. Example Project is available, if somebodey wants to take a look. Greetings and thanks alot

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 talpade on WAGO PLC 200 750-8216 Ethernet connection to Codesys 3.5 ^{CODESYS Forge} ^talk ^(Post)
Hello, I have the WAGO PLC 200 750-8210. In addition I have downloaded the "WAGO Devices and Libraries 2.0.4.3" and installed the library into the Codesys v 3.5. I then create a new project on Codesys 3.5 and select the device "750-8216 PFC200 (WAGO)" (which I downloaded from the WAGO library). However when I have connected the ethernet cable from the WAGO device to my computer and on my codesys 3.5 i press "Scan Network" on codesys and it does not detect the device. How can I get it to detect the device? (I have put the ethernet cable from my WAGO to the computer, but it does not show the device).
