An Affordable And Programmable PLC

Jean J. White

We’re all utilized to general function microcontroller boards these types of as the Arduino or its numerous imitators, but probably we really do not see as much of their industrial cousins. A programmable logic controller (PLC) is a personal computer built to automate industrial equipment, and arrives with protected interfaces and ordinarily a distinct PLC programming surroundings. Therefore [Galopago]’s perform with an inexpensive Chinese PLC clone is primarily attention-grabbing, supplying a route ahead to making use of it within the Arduino IDE ecosystem.

Opening it up, the processor is determined as an STM32F103, and the relationship essential to area it in bootloader method is recognized. Then it can be programmed from the Arduino IDE, even however its bootloader cannot be improved. Then to finish the process it’s needed to identify the several unique inputs and outputs by previous-fashioned components reverse engineering.

This PLC may well not be very as strong as some merchandise costing a lot more money, but it nevertheless represents a expense-successful way to entry a microcontroller board with substantially of the interface circuitry now put in that would commonly be needed for controlling machinery. We count on that we’ll be observing it seem on these internet pages in excess of the coming months, and possibly there could even be a further comparison in the air.

Asus RT-AXE7800: Another Cool Wi-Fi 6E Router

In late September 2022, Asus quietly released the RT-AXE7800 router — its fifth Wi-Fi 6E broadcaster after the GT-AXE11000, ZenWiFi ET8, GT-AXE16000, and ZenWiFi Pro ET12. Judging from the name, the new hardware seems to be another mundane Wi-Fi 6E router of a lower tier than the GT-AXE11000. But looking […]
