A lot of PLCs are just microcontrollers too. The Arduino Opta just uses an STM32H747XI which is a microcontroller. A PLC generally just has more protection, both environmentally and electrically ...

However, to wire an Arduino (or any other micro) to a PLC, logic-level translation (TTL to RS-232) is essential because of the inherent voltage level differences between TTL and RS-232 (see below ...

Software would be way down on the list of why you would pick a PLC over an Arduino for anything other than a home hobby project. Report comment. Reply. Roberto says: July 17, 2017 at 2:50 pm ...

Arduino as PLC is an open-source project that demonstrates how to use Arduino boards as a low-cost, efficient alternative to traditional PLCs (Programmable Logic Controllers) for industrial automation ...
