PLC – Power Key

I decided to go with a Power Key, meaning the motherboard will provide 24V, 12V and 6-8V on 3 separate pins. The module then decide what power it need by pin usage as illustrated below. The top image is my Power Servo Controller, while the lower one is PWM3. If a module need to select…

PLC – PowerServo

This is a 2 x Power Servo module I just made based on the PWM3. The circuit is very similar except I removed the DRV8313 and 3 of the current sensors. Controlling a servo is about sending a pulse at 50Hz between 500uS to 1500uS – and I have some 60Kg Servoes that can drain…

BSA – Using a PLC PWM Module

Using a PLC module (or any component) in BSA is straight forward – you simply declare an UML State symbol with the input/output events you need and set this as external with the selected interface protocol and addressing scheme. The protocol can be anything because BSA is after all just a visual specification, so the…

PLC – G491RE Template

I will be using a few MCU’s to create PLC Modules, so it makes sence to create a template – starting project for each MCU. The most obvious is STM32G491RE. This template contains MCU, CAN, RS485, Crystal, SWD, Leds, FRAM and PSU condenced as tight as possible towards one side. The template might change, but…
