I have a question for the Visu File Transfer Example. Is it possible to transfer more than one file from the plc to the webvisu with only one button click? How can i realize it?

Post by danielbeers on Automation Server + Pi Gateway + PLC w/ CAN ^{CODESYS Forge talk (Post)}
Hello, I have a project using some EPEC PLC's. Some of them are programmable using Ethernet and some use CAN. We currently have a Raspberry Pi that is acting as a gateway to the Codesys Automation Server and is successfully working for the PLC's communicating over ethernet. I am trying to achieve a similar result for the PLC's that have only CAN access. I have PEAKCan drivers on the Pi, and can successfully send/receive messages. But the Gateway does not recognise the PLC when scanned from the Automation server online. Is there a library or service that exists to translate the CAN messaging, to the Edge Gateway, and be able to achieve remote access with the Automation Server? Or is this not possible without creating something custom? Cheers, Daniel

Post by imdatatas on C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
Hello everyone, I downloaded the "Example: PLC Chat Net Base Services" example from the Codesys help site to review and try it out. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_plc_chat_net_base_services.html However, when I open and compile the example program with SP21 Patch2, I get the strange error message below regarding Visualisation component, and it fails to compile. " [ERROR] visuelems, 4.8.0.0 (system): VisuFbTabControl: C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr " Are others experiencing the error "C0138: No matching 'FB_Init' method found for instantiation..." when trying to compile example projects created with older versions of Codesys with a later version of the IDE? How did you overcome this problem? Could you share your solutions? Regards, Imdat

Post by edepalos on Text list from sd card ^{CODESYS Forge talk (Post)}
Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes... Thank You in advance! Br, Ede

Post by dim54 on multiple entry of the Owner password ^{CODESYS Forge talk (Post)}
I have to enter the owner password from time to time, even though I haven't closed the project yet. Is there a way to disable this option? So I only have to enter it once when I log in to the project, and that's it.

I have the same error. It appears to be something in my project. An older version of the same project from a few days ago is fine.

Solved: I started from a fresh project and everything worked. I had a Function Block in the project at one point and deleted it. I think Codesys doesn't fully clean up on deletes.

Post by chaoschaos on Visualisation generates "Unresolved reference" ^{CODESYS Forge talk (Post)}
For the DynamicText error i have finally found a solution. You have to delete some libraries from your project. For me it was the WagoSysIcon library which wanted to reference dynamictexts even though i didn't have any in my project.

Hello Zol6, Have you solved this issue? I use Festo PLC CPX-E-CEC-C1 to create alarm monitoring project. In CODESYS V3.5-SP18 I used the Alarm Storage object and have the same problem. Is it the PLC that is not compatible or the version of the library is not match? Best, wb16
