Ethercat Master/Data Layer/S-Parameter/Flatbuffer/Go-Lang

Ethercat Master/Data Layer/S-Parameter/Flatbuffer/Go-Lang

Dear everybody.

Just installed the ctrlX CORE - DRIVE Connect App and tried to get the value from the data layer generated by Connect App by Go-Lang.

I managed to get the value for S-0-0383.0.0 in the data layer:

So did I in the Go-Lang runtime (own written code); upon reading the flat buffer data type out of S-0-0383.0.0, the response gave me 160 bytes of data (flat buffer). The first 30 raw bytes separated by '|':

0x18|
0x00|
0x00|
0x00|
0x14|
0x00|
0x20|
0x00|
0x00|
0x00|
0x04|
0x00|
0x08|
0x00|
0x0c|
0x00|
0x10|
0x00|
0x14|
0x00|
0x18|
0x00|
0x1c|
0x00|
0x14|
0x00|
0x00|
0x00|
0x58|
0x00|

...

 

Is there any specification, how I can interprete those bytes to the readable JSON structure?

I suspect that the double sequence of 0x00 could be kind of separator - but not sure, though.

Any help and info highly appreciated.

It's possible to deserialize the FlatBuffers in go.  

But I would recommend to directly access and read in the values you can find as child nodes of the parameter. See my screenshot:

 I used the version 1.18 of the DRIVE connect App.
