hey All Am using ABB PLC with automation builder ,
So i have an HMI i use it to send the set points for presser , time ...etc ,
my problem is that when i shut down the plc ( remove the power ) and run it again , all these value become zero,
I think it is a problem in my code , i use these values as retentive and persistent and global and its seem to work when i cut off the power for one hour ,
but when i cut off the power for 18 hour , its become zero again So what i miss ? Thanks in advance .

Hi
What kind of ABB PLC are you using? What model? With which HW devices are connected?
A more detailed description can only help ...
Are you sure the data backup battery is in good condition?
Because what you write, a short break of one hour does not make you lose data, but a longer interruption yes ... if this is not a low battery symptom ....
