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.

Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

If I want to display level in the tank, what's usual approach? Is there tank or vessel element I can use? I see there is bar display, but I can't make it fill the shape I need.

The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

Post by squiggleypuff on Can't Add New Version of Modbus TCP Master
CODESYS Forge
talk
(Post)
I'm having a tough time trying to get Modbus working on a Festo CPX-E PLC; it throws these pre-compiler errors as soon as I add in my Modbus TCP Master 3.5.12.30 to my project: I'm confused about the C0046 error, as I have IODrvModbusTCP 4.3.0.0 Library installed. So I thought maybe I needed to use the newest Modbus TCP Master 4.3.0.0, which is in my device repository: However, whenever I go to add this underneath the Ethernet adapter (which is version 4.2.0.0), the only TCP Master version available is the old 3.5.12.30 one, even if I have Display all versions checked.: I even went so far as to delete the old version, but then there were no options to add a Modbus TCP Master under my Ethernet adapter. What needs to be done to use the newest Modbus TCP Master? Or are these pre-compiler errors unrelated and I'm missing something? Any help greatly appreciated.

Hello, I'm using CR711S from IFM and I would like to use the CAA Can Low Level in de Safety part. I already use it on the Standard part and it works properly. I would like to know if there is some restriction on using it on the safepart of the PLC (I tried but my PCL put himself in Stop...) ? And if you have some example or even a forum with some types on IFM and CoDeSys, I would Take It. Have a nice Day.

Hi, is there any solution to the problem? You can find the missing file in the C:\Program Files (x86)\CODESYS 3.5.19.60\GatewayPLC\tempCFG directory, but attaching it to the c:\ProgramData\CODESYS\CODESYSControlWinV3\<unique number="">\ directory does not solve the problem with visualization.</unique> In the log file you can find the entry: 04/04/24 13:32:44: --------------------------------------- ----------------------------------- 04/04/24 13:32:44: CODESYS Control Win V3 Service started 04/04/24 13:32:44: Config file: 04/04/24 13:32:44: C:\Program Files (x86)\CODESYS 3.5.19.60\GatewayPLC\CODESYSControl.cfg 04/04/24 13:32:44: ERROR: AddDllDirectory failed (2). Qt based components cannot be loaded In my case, the problem concerns versions 3.5.17/3.5.18/3.5.19 Reinstalling doesn't help.
