Does anyone know if I can use LibNoDave Ethernet communication with some of these modules:
6GK7 343-1CX10-0XE0 (CP343-1 Lean)
6GK7 343-1EX30-0XE0 (CP343)
6GK7 343-1GX21-0XE0 (CP343-1 Advanced-IT)
Is all of them compatible?
Is it also possible to talk directly to CPU 315-2 PN/DP, CPU317-2 PN/DP ?
Kind Regards
Thomas

I'm using 6GK7 343-1EX21-0XE0 with firmware version 1.0 and I have a problem to read data with "libnodave" on linux with gcc4.
I can communicate with CPU 314 (RUN-STOP is ok), but when I read a data block with "daveReadBytes" function, the section data of PDU is 0.
cheers

Hello Francesco, I get the impression you open a new contribution here! If this is the same CPU and CP you used in that issue, I can tell you IT IS NO PROBLEM of the CP VERSION!
You would never have got so far if it were!
PLEASE LEARN HOW TO OBSERVE THE BYTEWISE CONTENTS OF YOUR DB and I am shure you will see Libnodave is right!

Now I' m out of my laboratory and I 'm starting for summer holidays.
Probably you right . I'm not an expert of PLC S7 , However I got it in my laboratory to use it as a development & test device . So I can reset it whenever I want. I can setup the PLC using STEP 7 with one Data Block (DB1) with one byte (8 boolean datapoint with all values TRUE) and OB1 of default.
What should I read with "daveReadBytes(dc,daveDB,1,0,1,buffer)" function ?
keep in touch in September.
greetings and thanks once again

I used these two cards successfully:
6GK7 343-1CX10-0XE0 (CP343-1 Lean)
6GK7 343-1EX30-0XE0 (CP343)

ok
it is the same CPU and CP.
