Post by schnepper on Minor UI bug: cannot create SFC POU after creating a Function POU ^{CODESYS Forge talk (Post)}
After creating a Function POU, it is not possible to then create an SFC POU. Steps to recreate: * Create a new Function POU. SFC is not allowed for Functions, so SFC does not show in the Implementation language dropdown. * Click Add Object -> POU... Function is selected for Type. * Select Program * SFC is not present in the Implementation language dropdown

The green icon with an ! next to the device is concerning. Is the data type correct for the input, you are using a byte input but the description says string. Is there anything useful in the status tab?

Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
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.

Post by mubeta on UNION statement is not supported in the ethercat data exchange ^{CODESYS Forge talk (Post)}
Hi all, I am using a unionn statement for merge in integer data type some values that are received in byte from the i/o cards, but, using this simple and light technique, is not recognized by the ethercat data exchange and in fact the tags are not updated. In my opinion it's a very big bug.

Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Post by eguerra on Error in ScriptingEngine Docs - create_pou() ^{CODESYS Forge talk (Post)}
In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )
