Cameras Cognex (GSD DATAMAN)

esteban2147 · April 2022

I am trying to take the records from a camera (Cognex brand) communicated by profinet to an AXC F 1152 PLC, I was able to access some of its entries but seeing the examples they have with siemens they do not match.

I need to take the barcode that the camera captures and see it inside the plc

Has anyone worked with these devices?

I'm waiting for your answers

From the screen shot I am guessing that the process data item named "Result Data" contains the barcode information. Is that not the case?

Exactly, after searching a little more I found the solution.
I created a 64 byte array of data types and I was able to get the code in ascii(TYPE
    TEST_02 : ARRAY[0..63] OF BYTE;
END_TYPE), now I just need to pass the bytes I need to string

The BUF_TO_STRING function block should help with that. The camera should return the number of characters in the buffer, which will also need to be passed to the function block instance.
