Post by jinlee on Reading Camera Feed in Codesys v3.5 webvisu web element browser ^{CODESYS Forge talk (Post)}
Hi guys, I have been trying to use web browser element in the visualisation to connect with my IP camera. From the past few weeks, I have not been successful of doing it. I thought it would be very easy to just connect to the ip address, but apparantly it is not. I am using WAGO PLC PFC200 and my PC as a webvisu. or else can you guys please advice me on which kind of camera should I use as a CCTV system in my project instead of IP Camera. Ideally, I want multiple web browser elements to browse my IP Cameras in one frame. Kind regards, Jin.

Bitmap Image (outlined in Red in attachment) with it’s configure window open in Codesys 2.3.9.55. Image doesn’t show-up in on-line Web Visu (this project only). No problem with bitmap images in all other codesys 2.3 projects. Web visu in Internet Explorer since 2.3 Web visualizations don't work in Edge.

Post by timvh on library is not available ^{CODESYS Forge talk (Post)}
1) In the library manager of your project select "Download missing libraries". 2) In the library manager open the "Placeholders" dialog. In here find the Placeholder which is not referenced to a specific library yet. Click in this line on the Library column and select the latest version of this library.

Post by william on Unit testing support / libraries for EcoStruxure Machine Expert (CODESYS) ^{CODESYS Forge talk (Post)}
Hi, We are investigating available libraries and frameworks for automated PLC unit testing in Schneider EcoStruxure Machine Expert. Specifically, we are looking for: Assertion libraries or test frameworks compatible with Machine Expert CODESYS‑based solutions that are not TwinCAT‑specific Any official or community‑recommended approach for unit testing FB/FC logic offline We have found several open‑source examples, but many appear to be TwinCAT‑dependent and therefore not compatible. Are there any known libraries, best practices, or recommended approaches for implementing unit tests in Machine Expert? Thanks in advance.

Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>

Goodmorning, The projects we have made (with several persons) are in differents versions, Codesys V3.5 sp18 patch4, V3.5 sp19 patch 2, V3,5 sp19 patch 5 etc V3.5 sp21 patch 3 etc.. Now when we're opening an project thats's not opend before on my pc and we're not sure in witch version it's made it's quite annoying. We don't want to update to the newest version. Is there a way that it's automatic opening the correct version? Is there a program/tool/easy way to do this? Thanks,

So I found the mistakes. First I forget to deactivate "Use access rights defined in the user management". And also I used in "UaModeler" a project name with whitespaces, which lead to a wrong namespace name.

I've created a very basic version of this problem as a project. Please see attached. One of the libraries in conflict is different from that described above, but the problem is the same. My development environment is 32bit v3.5.16.70 using v3.5.11.0 compiler.

Hi, I have a Combivis studio 6 licence. What I need is information from Codesys about how the information 'Download time' is saved and if it is possible to modify it manually.

In the device selection. Do not filter on Phoenix. Remove this filter and first add an Ethernet Adapter from CODESYS. To this Ethernet adapter add the Profinet Controller. After this you can filter on Phoenix devices in the "add device dialog".

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco
