Dear all .

I made a program for boiler tank using TIA V15 , the program consists of 2 PID blocks in OB30 .

but the PID didn’t work automatically until i opened the PID block settings and choose start PID as shown in the picture .

and when i switched off the power then switched it on again , i must open the PID block setting and choose start PID also !!

Note : i choose the PID to work automatically as shown in photos .


I need your help to solve the problem .

thank you .
