Bottom line up front: Where is a good source to learn about S7 CPU to PC communications?
I found this thread, but it isn't really helping me: http://www.plctalk.net/qanda/showthread.php?t=100297
I have some engineers that I'm trying to get familiar with PLCs. I have delcared that we are a Siemens shop, so we only use Siemens S7 series CPUs (1500 and ET200 type, for our current projects). Our software is up-to-date using TIA Portal V13, WinCC Comfort/Advanced (I think; concur with rant in linked thread about Siemens' product naming structure and infinite number of versions being confusing).
What I need is something basic for my guys to be able to first communicate via Modbus TCP to some dedicated hardware - got this one covered. I then want them to learn to communicate to a PC to be able to store historical data offline, as well as importing the data into a spreadsheet for display and analysis.
Our industry is in a downturn, so I'm using this time for my engineers to bring their skills to a higher level now that we have some spare time.
Thanks for any links anyone can show me,
Don
