PLC or Arduino?

Question

Arduino

I collected, here, from a children's designer a toy on my head. Now I’m thinking what to choose to control such a thing with a PLC or Arduin and co.? It is assumed that there will be a two-level system - at the bottom of the controller, which moves the mechanisms, and at the top something like a WMS with a web face.

Answer 1

Thank you very much for the replies.
I did make one copy on Siemens Simatic S7-1200:

Now I will try to repeat on Arduino.
If I manage to overcome laziness, then I will publish a table for comparing the prices of SIE and Arduino components, which were needed to solve the lower-level automation problem.

Answer 2

choose what is "closer".

Answer 3

A PLC with that many I/Os will be as brutally priced as a dozen arduinos. Well, you will have to program in specific languages.
But for the arduino, you will have to match the levels to 24 V, so what can it be easier to do the same to the native controller?

Answer 4

"By eye" - missed, assuming that signaling positions is easier.
Yes, it is quite normal for a PLC.
Additionally, several, depending on the number of channels (usually from 8 to 32), DI and DO modules will be required.

Answer 5

It depends on what parameters are priority in the choice.
I would suggest focusing on the number of actuators and sensors (DIO / AIO).
And the complexity of their control signals.
According to the “by eye” assessment, in my opinion it’s too easy for a PLC (except to consider the weakest rulers),
and apparently this option will be significantly more expensive.
But more reliable.

Answer 6

It depends on what kind of development is expected.
If you are only interested in the production process, then only the PLC and nothing else, because arduins are not used in real production and almost everything is done on the PLC. Not a PLC, there are only single-board computers, in which, in fact, a software PLC is also implemented.

Answer 7

Look towards the Zelio line from Schneider Electric. Almost a child can assemble and configure, programming languages ​​are also very simple - they practically represent a logical circuit.
