(Notice at 16:50) deviate 5 hours from PC time. 3/ Move out and you will see Data_block_1.day.time = 4 (it’s mean 16 of 24 hour, the same with 4:PM) 4/ The Diagnotics PLC is synchronized with PC - So who can explain why there are some deviations in part 1,2,3. - Use RD_SYS_T function to write to the system time. Is OK - Can’t refer on support website of Siemens https://www.automation.siemens.com/W...31&language=en - In my opinion, there must be SET_TIMEZONE function in the program, but it can’t be set now.

Wish you success. Good luck. ========================== Bao Quoc ========================= Attachment Edit Error Time S7-1200.jpg (721 Downloads)

If you need just read your curent time from PLC, without rewrite, use RD_LOC_T: Read local time Info: "use this instruction to read out the current local time from the CPU clock and output this at the OUT output. Information on the time zone and the start of daylight saving time and standard time, which you have set in the configuration of the CPU clock, is used to output the local time."
