MVP 2021 kratmel Posted September 18, 2022 MVP 2021 Report Share Posted September 18, 2022 RTC is embedded to this PLC. You can find time and date in PLC Info mode. If you have project for V280 - you can add RTC to display. If you do not have a project and it is not burned to PLC (upload project is not possible) - you must program new project for add RTC on screen.

MVP 2021 Flex727 Posted September 18, 2022 MVP 2021 Report Share Posted September 18, 2022 You can also utilize RTC in ladder by using SI 30 - SI 38. There is also plenty of information in the Help file. Quote Link to comment Share on other sites More sharing options...

It's a standard controller that doesn't have upload and burn. If you lose the battery you lose the program. Joe T. 1 Quote Link to comment Share on other sites More sharing options...

Can you attach your program? Go online with the controller and look at SI 30 .. SI 38. Is SI 30 (Current second) incrementing? Joe T.
