Hello and thank you for this great Library.

Is it planned to make the TFU003 also working on a TwinCAT BSD system? Or is it somehow already possible to run it on BSD?

Hey.
Thanks for this code.
I had some issues since there is a mix of definitions in the sw/documentation with read/write and ReadFile/WriteFile.
In the Example, you use ReadFile/WriteFile, but in the actual library, you use read/write.

Hello

Overall, very good job, thank you for this code.
I tried two things on write:

1. Wrong variable name to input "File" (variable doesn't exist) - No error, no file created, no feedback
2. If data array/structure is huge - No error, no file created, no feedback

This is async function block so will be nice to see some feedback from it like: Busy, Done etc
Even using this FB without TFU003 installed, done nothing without any feedback

Hello,

is it possible to use this library on a CX9020 with Windows Embedded?

I Installed your lib but i get the error code 1862.

In your function you start a .exe in the background,right?

Is it possible to start .exe with Windows Embedded like on a CX9020?

Hi Frederico,
Was trying to use the library ( locally on my laptop) ( both read and write) but I can't get it to work :( . The code runs but doesn't read/write to/from a JSON file. and I'm not getting any errors either. is there anything that I miss ? I appreciate any help

Hello Frederico,
could you please help me with using your library.

I am using the following json:

{
  "name":"John",
  "age":30, 
  "car":"blue"
}

My MAIN looks like this:

VAR
	parser : JsonParser;
	Json_Content : STRING(255);
	a : STRING;
        json : json_st;
END_VAR
parser(
	Execute:=FALSE , 
	File:= 'C:/temp/json_test.json', 
	ParseMethod:= 'Read' , // or even 'Write'
	Content:= 'json',
	HasError=> , 
	ErrorId=> );
a := json.name;

And lastly this is my struct:

TYPE json_st :
STRUCT
	name : STRING;
	age : INT;
	car : STRING;
END_STRUCT
END_TYP

The Code is getting executed so far, but the Struct Variables do not get updated with the Json Variables.
I tried lots of different things but do not see my problem. Could you please help me?

Thanks a lot

Hi there.
Thank you for this library 👍.

I have an issue while importing the JSON file to the structures. If I import it to a structure with ARAYS inside, it's fine but, if I try to import into an ARRAY OF STRUCT, it will not import nothing.

Can you confirm this issue?

Thanks
