I have a single wincc station with siemens S7 PLC in one of the project.Yesterday while checking trends i found the time of trends and actual time are not matching.I observed that the time recorded in trends is same as my computer time and somebody changed it.
How can i avoid it from winCC so that it will not folow the time from PC ?
