Over the years there have been several times you upload a video and you're messing with the same thing I am, always found that to be a funny coincidence. Although its happening less now that I've moved away from Automation Direct PLCs. Have you ever messed with any Beckhoff stuff? I think you would have a lot of fun with it. The program environment is free in a way that's good for educational stuff like this and their hardware is decently priced. I switched to Beckhoff recently because of the platforms nearly endless possibilities and user friendly support.
Hi @Fine_i_set_the_handle I have not had the opportunity to use the Beckoff PLC. I believe that it is the TwinCat 3 software. I'll will reach out to them. Thank you, Garry
Can you recommend some hardware from Beckhoff that would be good to utilize? I am especially interested in communication with Modbus TCP and MQTT. Thanks, Garry
@@ACCautomation You can actually just use an old desktop or laptop you have around with twincat 3 XAE software to turn it into a temporary beckhoff PLC. It can use MQTT and Modbus TCP without any special hardware. A desktop pc with XAE software will also be compatible with their ethercat hardware (EK1100 bus couplers and relevant IO cards). I bought some Ek1100(field coupler) el1809(16 digital input) and el2809(16 digital output) cards off ebay for a few hundred to play with a year or so ago and had a blast.
Here is a thread that will discuss how to do this. stackoverflow.com/questions/25682962/timers-in-plc-structured-text I hope this helps you out. Regards, Garry
