Thanks!! It was really helpful. Now I get the basics of PLC
Very Good , Fahad Bhai , Nicely explained. Many Thanks, Sharad (India)
I really enjoyed the simplicity of your explanation. Am completely to this and I wish to learn from you and want you to be my mentor.
Hi Fahad, thank you for the clear walkthrough.
Quick question though. In your video it shows the timer counting up in red in the timer block and I like that visual feedback while running the program. Was there something that you did to make that show? On mine everything works perfectly, but there is no visual timer that counts up. Also, on mine there is an automatic Program Unit Comment that was added under the “EN” on the timer and the “T50” b input that just says “timer”. Is this a matter of the program version? I downloaded the V3.31 version updated 9/20/2023 from the Fatek website.
Thanks again,
Kent
