Robotic System Sanity Check

Can someone tell me if I am missing anything? This will be my first ground-up system design.

Thanks!!

do you mind explaining the architecture or actual goal behind this?

it appears that you plan on using small non-safety PLC to collect diagnostics data from several small safety controllers (Banner SC10-2ROE) and then passing this data to Node Red over Modbus/TCP.

Yes, I was under the impression that safety signals can not be sent over ethernet but I also want to be able to monitor all systems remotely. So, my thought was that I could use the Banner SC10-2ROE for necessary safety inputs (EStop, Doors, etc) and then send relevant data to a Siemens PLC. The Siemens PLC can then pass data to/from other Banner PLCs and be connected to a Node-Red service for purely monitoring purposes.

The goal I guess would be to pass coords from vision to the robot and signal conveyor movement based on vision as well. Generally, its function is a pick-and-place routine with a couple of extra steps.

Why use so many controllers? You could use S1200F which is a safety plc

So your suggesting skip the banner PLC's and only use a single s1200f? Would it be capable of handling ALL the aforementioned functions?

As panic mode said, use one safety plc. Then you are flexible, safe and probably cheaper. Never have seen such a complicated design. Exeption would be if all the different components will be independend and programmed by different suppliers.
