love it, thanks for the new videos! The power grid project you're putting together is awesome - your students are very lucky to have such an inventive teacher. Your channel has inspired me to start getting into automation, I recently picked up a Click plc and am replacing my homes thermostat and light controls with it. I'll be sure to make a video of the finished project!
Hi am doing something similar, with siemens S7-1200 PLC and SEL 751A Relay. But for some reason I am having trouble communicating both devices thru modbus rtu with rs232 cable :(
