Hi, what function you've written? Have you try synchronize time using this FAQ: How do you synchronize the time and date of an HMI Basic Panel with an S7-1200 PLC using the "Job mailbox" area pointer? regards |

Do you mean that the PLC and HMI software time are the same but the machine on which the HMI is installed is different. No, The time at HMI, PLC and PC are the same and is correct. I set the time in PLC with "Take from PG/PC" in "Set time of day" in "Online & diagnostics" If not can you check the time on the HMI machine? Is this the same as the alarm time? When triggering a bit (as a part of a word)(which is defined as an HMI-alarm) in PLC, the time that occurs in alarm-display at HMI is totally wrong. It is the internal time of HMI which occurs when HMI is not syncronized with PLC (always start at 2004). Or does the Alarm's take a default start time as if it has just started. Yes! Starts at 2004-01-01 Try resetting the server parameters of the HMI. Where do I find these "server parameters"? In WinCC it is re creating the Server Data. Perhaps I've done a big mistake or a misunderstanding of HMI-alarms? I've attachthe test project which shows the problem AttachmentTimeDate.zip (990 Downloads) |
