Hi I am looking for a tool that can detect changes to a program running in a Siemens or Rockwell PLC.
We do have a sw archive for this, but many changes are made to programs without being archived.
I'd like to compare the latest copy in the sw archive to the current running program, to see...
I ran into an Ethernet (TCP) based protocol which sends packets like (in ASCII):
28253199166202202220008+0041808825319_4F7
I can't find what it is, does it sound familiar ?
