Hi
Im relatively new to any plc programming and now i took a challenge to program one to my friends company. im ok with basics, atleast i think i am but one thing has been bugging me for a week or so now.
What im trying to achieve is that when i turn the process on by push button timer turns on and the inverter and keeps running motor for set ammount of time on 100% when time is up it starts another timer and runs motor for 90 minutes but only with 75%. thing i can´t figure out is how i can set analog output automaticly to smaller value when 1st timer runs out? well i have no idea how to set analog output to a value at all without doing it manually from the screen.
any help would be great.
thanks
