Post by khaledkhalil on Import OPC UA model to Codesys ^{CODESYS Forge talk (Post)}
I have added a models in SiOME which a software to design nodes and add instances. and created a resultant xml file. I tried to import the xml file to Codesys through OPC UA information model Repository the problem i don't know how to view my objects which i have designed. and map it to my PLC to make viewable on my server UaExpert. I watched the tutorial video https://youtu.be/aJhzN3Uk-Do?feature=shared. But it only give you how to add the Information model, and my resultant model doesn't have information type. So how in Codesys i can view a model which i have designed in SiOME and mapped my instances (Objects, Variable or methods) with my Variables in PLC I saw people do it in Tia Portal or other Software, but i have no clue how to do it on CODESYS

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

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 gatto on variables between two applications ^{CODESYS Forge talk (Post)}
Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

In my case, I used a different version of gateway. ex)3.5.18.5 sysTray gateway start did not work, so I terminated it and made it work with 3.5.18.3 in "codesys installer" "Settings" and was able to connect to the PLC.

Post by nickelwater on Fix compiler version in SP18+ ^{CODESYS Forge talk (Post)}
Is is possible to use the compiler "Fix Version" in SP18+? I have noticed that in SP17 and below, the option is available in the compiler options under project settings, but in versions 18+ it is unselectable. The help topic does not provide any information.
