Heitor Posted December 13, 2018 Report Share Posted December 13, 2018 Hi. I'm need help for the function storage the date. Is possible to monitor the time when the output is up? My proccess need a logic for to monitor a output but the time can isn't reset when the output is down. I'm monitoring the useful life of lamp. The time need reset when a lamp is replaced. Is possible with V350-J-TR20? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted December 13, 2018 MVP 2023 Report Share Posted December 13, 2018 Just increment a register (ML) with contacts SB 13 and your output in series. Divide the result by 3600 to obtain hours. Unless the PLC battery dies and 24V power is removed the PLC will retain all register values.

MVP 2023 Flex727 Posted December 14, 2018 MVP 2023 Report Share Posted December 14, 2018 The PLC battery will last for years, but is only used when there is no 24V power applied. Quote Link to comment Share on other sites More sharing options...
