Hello,
I have a bunch of old discarded PLC, that I would like to reuse to some projects. But I have absolutely no idea, where to start and what I need for it - which programming software,programming cables or other accessories and how to do it.
The PLCs in question is S7-300 and ET200S. I have tried to do my research, but have not found much definitive info, as to what I need to program them or do anything with them. I have found out that in the past, some "STEP 7 Lite" software was used on the PC side to program them, unfortunately this software is obsolete and no longer available. The replacement should be "TIA portal" or whatever it is called. But it seems a whole lot of mess to a beginner, I have really no idea, where to look first.
So can anyone please point me to some manbual/tutorial, or simply write in short, what are the required tools to work with these?
Thank you for any hints, meanwhile, I will try to look further, if I can come up with anything. I have unforutenately no previous experience programming any Siemens PLCs, so am out of ideas.
