An Affordable And Programmable PLC

An Affordable And Programmable PLC

We’re all utilised to basic purpose microcontroller boards this kind of as the Arduino or its lots of imitators, but potentially we don’t see as much of their industrial cousins. A programmable logic controller (PLC) is a laptop or computer designed to automate industrial machinery, and comes with safeguarded interfaces and commonly a distinct PLC programming surroundings. So [Galopago]’s operate with an reasonably priced Chinese PLC clone is in particular interesting, delivering a route ahead to making use of it in the Arduino IDE ecosystem.

Opening it up, the processor is discovered as an STM32F103, and the relationship required to location it in bootloader mode is determined. Then it can be programmed from the Arduino IDE, even nevertheless its bootloader simply cannot be modified. Then to comprehensive the approach it is necessary to determine the several unique inputs and outputs by previous-fashioned components reverse engineering.

This PLC may not be very as robust as some merchandise costing a great deal far more funds, but it continue to represents a price-powerful way to accessibility a microcontroller board with substantially of the interface circuitry presently set up that would normally be demanded for managing equipment. We anticipate that we’ll be seeing it seem on these pages more than the coming months, and perhaps there could even be a different comparison in the air.
