I try to use the HMIRuntime.FileSystem.ReadFile() Function to read some data from a textfile.

I am following the definition from the "WinCC Engineering V16 - Runtime Unified System Manual"

myCode:

let tag3 = Tags('tag3');
let tag4 = Tags('tag4');

HMIRuntime.FileSystem.ReadFile("C:\\Temp\\key.txt",
'utf8').then(
function(text) {
tag3.Write("Text: " + text);
}).catch(function(errorCode) {
tag4.Write("errorCode: " + errorCode);
});

I recive the errorCode "2156935125". Any ideas what this error meanes?

Hi, Did you find where the error codes are listed? I have the same problem for writing...

Thanks.

Here you have a list of error codes based on trial & error, I couldn't find any official information about this: 

Hello rdoliveira,

can you tell me, where exactly you set the permission?

thanks

 Hi,

I have the same problem (V17). If I use the root drive like:

HMIRuntime.FileSystem.ReadFile("C:\\key.txt",'utf8').then(

It works, but when I use a directory like:

HMIRuntime.FileSystem.ReadFile("C:\\Temp\\key.txt",'utf8').then(

I got the "2156935125" error code. The folder security is set to Full control.

Anyone has a solution for this?

Hello, a comment, I had an error in writing and I had the error 2156935121, I made the permission in the folder, for writing and it worked.

 Hello rdoliveira,

to which User did you assign the permissions?
