We walk before we run. If we limit ourselves to being perfect out of the gate, we will never get out of the gate.Now don't get me wrong, as a developer of both platforms I hate those expensive 25k RAM (!) PLCs and all the visual programming nonsense that comes with it, but it's really still the only viable option if you need RELIABILITY.
So, the real question then is what would it take to build a PI with the same level of reliability as a PLC?
Not at all. It is just a different perspective.jstokes5 wrote:Sorry if I offended rm. I was joking. I'm an electrician myself.
It sounds interesting, but all I seem to be able to find are descriptions alluding more to monitoring features than programming one.ranpitime wrote:Hi
>now maybe I'm missing something, but how does the software you're promoting help use the Raspberry Pi as an actual PLC?
ok, sorry will not do it again, (the Intension was more how to do it)
but the answer to that question is a clear yes, it will turn Raspberry PI to an actual plc... that's it!
Thanks for the fair warning!
Hmm... An interesting question. I bet everyone will have their own answer to it If you're asking as long as the Pi can turn on and sense digital signals and measure and source analog signals (which is 95% of what a PLC does) then why do we need to make it a full blown PLC since it's already doing everything a PLC does.SGPIGLF wrote:Hi to all,
I am new to Raspberry Pi ,control engineering and PLC System. I thought as long as the system is able to perform the function design for it will be good enough. Why is there a need to get Raspberry Pi to becomes PLC System?
Do understand from the discussion above on Safety which I agree but in many situations there are external circuits connected to raspberry pi that can be designed to incorporate the safety requirement I guess..... Correct me if I am wrong or enlighten me on it.
Hope to learn more about all the experts here. Thanks.
Exactly that was the spirit when this thread was started back in 2011. We succeeded to make thinks moving to that direction.abishur wrote: .....That's just WAY too expensive to use in a class room environment. I can't even get my company, a PLC programming company, to purchase a training PLC for new employees to learn on for that price! But a $50 solution that used the Pi and gave just a handful of electrically isolated I/O and maybe an ADC with a could analog inputs? It wouldn't be much but it would be more than enough to teach new employees the basics and would be almost 3 times less than the last useless college book I bought!
That is something! and I believe the best is not seen yet! Nice work @DWomack.DWomack & 3S answer wrote: So you won't need an extra license dongle unless you want it explicitly.
The fully licensed product without runtime limits will have a price of 35€.
