Post by siscu on Raspberry Pi: List of available example applications ^{CODESYS Forge talk (Post)}
Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

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 shooxplc on How to call the same program from library and get the vars updated. ^{CODESYS Forge talk (Post)}
Hi, I am writing to you today because I would like to create a library that would contain a program with its various subprograms, in my example "PLC_PRG" with "a", "aa", "aaa". But once the library is created as shown below: I would like to be able to drag and drop my folder as many times as I want (let's say I manage the same system multiple times). Once the drag and drop is done, we can see the second folder with the variables renamed successfully. As shown below: But my variables in CAD_1 remain the same as for CAD, so it's PLC_PRG instead of PLC_PRG_1, for example. Is there a solution to automate this? I wouldn't want to have to rename all my variables manually, considering that in the program where I want to do this, the number of variables is substantial. Lucas.

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).

Post by jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

You have to update the device in your IDE to 3.5.14 or you can contact your Codesys runtime supplier to know how to set the connected system to 3.5.19

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex
