You won't find 24 V logic chips so you will need level converters. Your discrete logic approach would have been OK in the 1980s but not anymore. | |

added tags for plc, industrial; fix typos

| Jun 5, 2020 at 9:22 | comment | added | Neil_UK | PLCs were brought in as a programmable alternative to fixed simple logic gates. Nobody in their right mind would today automate something with solder-down logic, when it can be done programmably. Find the right small PLC. What happens when you want to change it? What happens when the customer wants assurance that it's suitable for the rugged factory environment? | |
| Jun 5, 2020 at 9:17 | comment | added | MarkU | Yes, microcontroller requires programming, PLC requires ladder logic, CMOS/TTL logic gates require digital design, CPLD/FPGA require HDL design. Any of these tools will work (PLC is best for harsh industrial environment), but they all require defining the actual work that the system must perform, in detail. Same approach is needed in all cases: first define the scope of work, document the existing system requirements. Determine the available cost budget and time allowed. Determine whether additional skill sets are needed, either to learn, or to hire an engineering consultant. | |
