Hello geddawy_79, If you want to select between Back-up batteries and external power supply to keep the content of internal RAMs inside CPU intact , it depends on the situation.In case of using RAM external memories, the importance of back up voltage strategies is doubled.
Personally, I think using original back-up batteries is also reliable if your systems's down time is not very long to consume more from batteries.As an example "6ES7405-0KA02-0AA0", supports 2 back-up batteries and with a simple program in OB81,You can detect a dead battery then generate an alarm in your SCADA for change. In brief, my suggestion would be using both strategies simultaneously and my prefernce would be batteries for normal cases.Read more HERE for battery failure detection. I hope this helps, Hamid Hosseini |
