Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.

I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

Hi William, I struggled in the same way as you at the beginning with the recipe manager. This chapter helped me a lot to understand how it has to be used: https://content.helpme-codesys.com/en/CODESYS%20Recipes/_rec_start_page.html Check out the Methode LoadFromAndWriteRecipe / LoadAndWriteRecipe Good luck!

Maybe your question makes sense but I don't see it. Maybe you should rephrase and add a lot of detail

Post by davidbo on How to stay in a method until something is finished. ^{CODESYS Forge talk (Post)}
You never stay in a method. You need a block to do that. Something like: VAR button:BOOL:=FALSE; count:UINT:=0; END_VAR IF button THEN //read pressure count:=count+1; IF count>1 THEN button:=FALSE; count:=0; END_IF END_IF

Thank you @eschwellinger Even tough I think the content of the link you provided is a bit messy. To bind OPCUA server to a specific adapter, I should have had insert the following section. [CmpOPCUA] NetworkAdapter=eth0 But it doesn't work, I had to insert the following section instead to get the right configuration. [CmpOPCUAServer] NetworkAdapter=eth0 Regards Rossano

Post by vstrom on Recipe definition, how to have the Name string in current language? ^{CODESYS Forge talk (Post)}
I'd like to know if it is possible to have the "Name" field, in the recipe definition, language dependent. Something like to have the possibility to put there a string ID that will be add to the GlobalTextList. In this way it can be translated and when showed in a Visualization screen its value depend on the current language. Thanks.

Post by jwhaley on C0007 Errors ^{CODESYS Forge talk (Post)}
I ended up figuring it out It wasn't in my code. It kept taking me to 2 of my visualizations but it wasn't going to anything specific. Figured out it was some arrows that I had made to buttons for a mouse click to go to the other visualizations. I removed the text in the assign box but didn't remove the action "change shown Visualization from the list. If I deleted the images all together, the error went away. That's how I thought to go look at that.

I have a raspberry pi trying to add encoder to it using that free encoder node. I simply dont understand where the encoder channel A/B suppoded to be mapped when i got to I/O mapping on encoder I get nothing to where to set the channels for the encoder or is there any blocks from a library or how is it that you use an encoder with Codesys it doesn't seem clear at all

Post by nano on How to access to variable value through symbolic string name ^{CODESYS Forge talk (Post)}
i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

Post by mdetrana on VPLC Section 'Gray-ed Out' ^{CODESYS Forge talk (Post)}
When evaluating Codesys functionality, I found that the VPLC tab under Deploy Control SL > Operation > VPLCs is 'gray-ed out', see attached image. I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help.

Post by kevinrn on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
Hello community, I just want to inform you about our plans and the current status of automating the build process for CODESYS libraries. So it might be helpful for some people who are in the same situation. Background story: I am a software engineer at powerIO GmbH, normally I use high level languages for the products we develop and offer. Sometimes I work with my team on CODESYS libraries, which can also be found in the CODESYS store. Most of the time I spend with them on architecture tasks and tasks that are not directly related to our products. Every time I see the manual processes for releasing a library etc., I am very surprised about this time intensive process. Current situation: I know there has been a scripting interface for years. CODESYS Git was released a few years ago, but the scripting interface was only released a few months (weeks?) ago. We developed a pseudo-automated solution a few months ago, but it was all very hacky. So now there is a better Git implementation and also more modularization and installation options. For example, the CODESYS installer has a full CLI, which makes it very convenient to install CODESYS installations headless. Plans: I think it's the right time to develop a better automation solution. Most of our software projects are hosted on Github and we use Github actions very intensively for other software projects. Therefore, we have decided to use Github for our CODESYS library projects as well. Following tasks should be implemented in automation for CI/CD tasks: - Automated setup of CODESYS installation (Already released: https://github.com/marketplace/actions/setup-codesys-installation) - Checkout CODESYS libraries - Execute tests scripts - Sign CODESYS libraries - Extract Library documentation - Create CODESYS package - Sign CODESYS package Side Note: - This is mainly a side project, and we do not provide support for the CI/CD part. - This topic is here to help and also to get help from other software engineers. - This project and idea is not prioritized as I am currently the only one working on it and I hope it will help us and also others and increase productivity. - We are putting this out there as an organization, but priorities can change quickly and the CI/CD tasks I am developing are mostly done in my spare time. So please don't expect this to happen in a short time or even be fully completed. I would be very happy if some ppl will join the development process and might be open to discuss some technical details for this. I hope this topic is not to off-topic, but I think the CI/CD part is very important today and it can increase a lot of quality and push productivity. Thanks :)

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Post by gatewail0 on Digital Clock ^{CODESYS Forge talk (Post)}
You can definitely pull the actual system time into CODESYS without too much trouble. Take a look at the SysTimeRtc or SysTime library—both let you read the current date and time from the Raspberry Pi. You can call SysTimeRtcGet() or SysTimeGetTime() in your PLC code and then format the hours, minutes, and seconds into variables that feed your 7-segment visualization. Once you’ve mapped those values, your Visu display will update automatically each cycle. It’s a pretty common approach for clocks in CODESYS, so you should be able to get it working quickly. golf hit

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hi, i found a solution for me. I had installed a 'old' version of CoDeSys (3.5.18 P5). I tried to add channels there, which works fine. I created a new project, added an Ethernet-Port, added a Modbus-Master and then I copied the ModBus-Slave from my working project to the new project. Now I could add more channels. I add the channels 10 and 11. Then I deleted (please make a backup before :-) the original ModBus-Slave in my working project and copied the extended Slave back to my working project. Surprisingly it is now possible to add new channels. Maybe this will help you.
