Currently I'm working on a university project based on Star/Delta Starter on PLC. I wrote program using LD, that switches on the circuit with a motor rotating forward (of course with star/delta starter - here I've used TON timer), then with another start button called "Start back" after pressing "STOP" I can turn the motor on backwards. Everything is working fine. Now I'm trying to figure out how I can set the delay after pressing STOP button (let's say 8 seconds) to block user with pressing START button with another direction.
For example, motor has been started forward, then we press stop and we cannot press "START BACK" until 8 seconds will elapse (to secure the motor).
I was trying to use TOF timer 2 times (one timer for Forward and one for Backwards) but it doesn't solve the problem. Is there any logic way to solve this problem?
Thanks in advance,
