Hi Chris,

thank you for that nice report (I won't make it to Nürnberg this year).
It is great to hear that, also the "big players" seem to start to shift their 
points of view (well, you cant turn around an aircraft carrier in one day). 
We see that movement already with many of our small and medium-sized clients 
but I didn't expect it to happen that "fast" in this area (even expensive PLCs 
have like 4MB RAM... and yes, I'm talking about MEGA bytes).
Did you get any "deeper" interest from anybody in the sense of "hey of course 
we can hack some days together with you and implement our protocol"?

And I agree that this is perhaps (not yet) a result of our work as the PLC4X 
community but I would definitely say that this is, at least to a certain amount 
a result of YOUR work. Of your vision, of all your visits to fairs, talks, 
presentations. This is my personal opinion but I'm pretty sure there are more 
people here on the list thinking the same way.

So let's keep going on rocking this shit... there's a whole industry waiting to 
be evangelized to the OSS side of things.

    Hi all,
    
    today I had my second visit at the SPS IPC Drives in Nürnberg. It’s one of 
the world’s biggest (if not even THE biggest industry fair on everything in 
industrial automation).
    Last year people treated me with sort of an attitude of being someone with 
really strange point of view. This was with the first line of PLC4X being about 
1-2 months old.
    This year people (even sales guys) seem to have gotten used to the 
industry. I wouldn’t say that’s our work, but at least things seem to be 
changing.
    
    Also I visited all the big PLC vendors for my annual “Who’s an Ass and 
who’s not” ranking ;-) Last year most of the companies in business for over 50 
years were on the red side of the list.
    
    This year, the worst I got was a: “But we don’t want you to do that” from 
Rockwell.
    
    On the Opposite side, I have to mention: Beckhoff and Phoenix Contact. 
These were extremely kind and seem to have adopted and embraced the idea of 
Open-Source.
    
    The other ones that were “just nice to me” were:
    
      *   Festo
      *   Rexroth
      *   Codesys
      *   ABB
      *   Schneider Electric
    
    Also I had a talk with one of the Profinet guys.
    The takeaway from that was, that we don’t need to become a member in order 
to be allowed to implement a driver. We can simply purchase the Specs.
    If we want to actively communicate (Active-Mode Driver) we need a 
vendor-id, but we could get that for free too. I was asked to contact the guy I 
talked with after the fair and he would send me all needed information. The 
only thing we are not allowed to do without a membership is use the ProfiNet 
Logo … guess I can live with that.
    
    So guess there’s nothing preventing us from implementing a ProfiNet driver. 
:-)
    
    Also did I do a quick summary of which protocols we would need to talk to 
the different types of PLCs:
    
      *   Rockwell: Ethernet/IP
      *   Phoenix Contact: Ethernet/IP, Modbus-TCP, ProfiNet
      *   Festo: Ethernet/IP, Modbus-TCP, ProfiNet
      *   Pilz: Modbus-TCP
      *   Beckhoff: ADS. OPC-UA
      *   Rexroth: OCI (MLPI for PLCs, EAL for Drives)
      *   Codesys: Codesys (Profinet, OPC-UA, Modbus, via plugins)
      *   ABB: Codesys, Profinet, Modbus-TCP
      *   Schneider Electric: Modbus-TCP (simple PLCs), EtherNet/IP (Controll 
Systems)
    
    So it seems implementing ProfiNet, Codesys and OPC-UA would increase the 
coverage even more.
    
    So far my summary …
    
    Chris
