Feasibility of OSS alternatives to RSLOGIX, Step 7, et.al.

Originally posted by Curt Wuollet on 28 February, 2005 - 8:44 pm

I've been working with a variety of projects lately and diagnosing problems with the usual tools, which vary from pretty good to abysmal. As I've been doing this, it occurs to me that it should be possible to reverse engineer the protocols and datagrams and build applications that do the same things with OSS tools.
