MVP 2022 kratmel Posted November 8, 2021 MVP 2022 Report Share Posted November 8, 2021 If it is possible to connect to old PLC - you can read operand and save it. After download project to new PLC - you can write saved operand from file. I think you simply do not remember timer value setup and if it resetted to 0 - blinking is normal behavior Quote Link to comment Share on other sites More sharing options...
MVP 2022 Ausman Posted November 8, 2021 MVP 2022 Report Share Posted November 8, 2021 Kratmel is likely correct. The unanswered question is "how fast"? On the forum there have been references to extremely fast blinking being caused by screen section overlaps. I know this shouldn't be the case in a change-over scenario, but perhaps worth checking to see if it makes a difference. Look for anything on that screen that is close together and re-arrange slightly to test. cheers, Aus Quote Link to comment Share on other sites More sharing options...
