Multi Array and Struct of Struct of ... Issue

[mehmetbezenk]

I encountered 2 problems while generating json. I want to create multiple array in a struct and struct of struct of ... .While debugging, I realized that it was caused by JSONVAR (FB) and made changes.

1. Change: I added at this statement for struct of struct of .. issue . You can look at added attached image.

2. Change: I changed this statement for multiple array issue. You can see it at image.

Example of created json (struct of struct of.. ):
'{"header":{"stamp":{"sec":1666700230,"nanosec":666597925},"frame_id":"asad"},"goal_pose":{"position":{"x1":3.212,"y1":1.656,"z1":2.977},"orientation":{"x2":3.212,"y2":1.656,"z2":2.977}},"velocity":0.123,"acceleration":5.986}'

Thanks for the library.

Hi Memeht,

I teste your case, it still doesen't work with the lib of Tim.

I'm implementing your changes and will suggest Tim an new version.

With your changes I get:

{"test3":{"header":{"stamp":{"sec":1666700230,"nanosec":666597925},"frame_id":"asad"},"goal_pose":{"position":{"x1":3.212,"y1":1.656,"z1":2.977},"orientation":{"x2":3.212,"y2":1.656,"z2":2.977}},"velocity":0.123,"acceleration":5.986}}

Bevor:
{"test3":{"header":{"stamp":{"sec":1666700230,"nanosec":666597925},"frame_id":"asad"},"goal_pose":{"position":{"x1":3.212,"y1":1.656,"z1":2.977},"orientation":{"x2":3.212,"y2":1.656,"z2":2.977},"velocity":0.123,"acceleration":5.986}}

Hi Mr. Stefan,

I have new problems.

1. I am writing variable at number of the json_var. I do not set value type. I want to set variable as real and I'm writing the counter increment at number of json_var. The changes are in the integer json_var. In the integer of json_var, it also writes the multiples of 10 to the number of json_var. So, I don't see the changes in between ( ie. xx10-xx20 ) numbers.

*******IO_Value : ARRAY [1..255] OF JSONVAR;

2. Sometimes It fills the json object incompletely or incorrectly.

Thanks,

Mehmet

Hi Stefan,

I am trying this new version but I have new problem with this.

Also I think we should add the one in bottom picture.

Also Old problem is continuing...

Hi Mehment,

can you provide a simple program wich raises the problem?

Further more, Tim implementet a function which cuts of the trailing zero:

do you need it?

maybe a parameter will be usefull for that.

Hi Stefan,

I'm sorry for the late reply.

I converted my project using network variable. But I prepared a simple program for you. You can download from the link below.

I think I encouter this problem as well.
Where I wanted to get cns: [["ip", "10.1.1.5"],["mac", "00-30-AA-AA-AA-AA"]].
That would give me "cu":"http://wago.ii""cns[1]":["cns[2]":[]], and is an non-valid json aswell

Hi Mehmet,

MAX_NAME_SIZE solves your Problem, your array name is too long:

What ist the "old Problem" missing ".0"?

@meijer3,

this is a different Problem, you want a anonymous array in a array. A named array would work.

Hi Stefan,

I'm sorry for the late reply. I am busy at these days.

I do not any problem because of too long array name.

What ist the "old Problem" missing ".0"? ==> It's not a problem with the library. I work with large and floating numbers. You can understand what the problem is from the images in the attached document.

Note : When I had a problem with the library, I used network variables. I plan to use it in next projects.
