Which is better, a quantitative loading device made with a PLC or one made with a microcontroller?
Thread Content
Currently, there are two types of quantitative loading instruments available in China: one is integrated around a PLC as its core, and the other uses a microcontroller such as ARM as its core. The design institute can’t tell which is better or worse. Have any users used a quantitative loading device? Please share your opinions.
Quantitative loading devices are all integrated systems, developed by the manufacturers themselves. Even if you ask the manufacturer to use a PLC, I guess they will still give you an encrypted program!
That’s right; therefore, some design firms claim that claiming that a PLC-based quantitative loading device allows users to carry out maintenance on their own is nonsense – the PLC programs cannot be made available, which increases reliance on the manufacturer
In my personal opinion, the loading device made with PLCs is nothing more than a PLC placed inside an explosion-proof enclosure, complete with a keyboard and a display!
It must be that way! However, this type of system is relatively easier to maintain!
The overall reliability of PLCs is several orders of magnitude higher than that of microcontrollers! When it comes to PLCs, you definitely choose top-tier brands, but microcontrollers are integrated circuits developed by the manufacturers themselves or designed and manufactured by others. How good can such integrated circuits be? Anyway, we still encounter problems from time to time!
That makes sense; a PLC is also built using a microcontroller. The performance of a microcontroller depends largely on the chip chosen
A decentralized loading device costs less than 10,000; how is it possible to use a PLC for this purpose? It seems a bit extravagant. Usually, a single-board computer is used, with the signals being sent to the upper-level equipment.
