The NTP server synchronisation is configured in the PLC properties.

Consult the network administrator for more details. Some technology networks even operate their own internal time servers, so the NTP time synchronisation is possible even without Internet access. If the PLC is in a network with Internet access, a NTP server can be used for time synchronisation.

If the PLC and PC are located in different time zones, this may not be an error. Therefore, it may happen that if the PC and PLC have different setting of time zones, the PLC time will not be the same as the PC local time. The time displayed in the PLC is the UTC time set in the PLC, recalculated to local PLC time according to the time zone which is set in the PLC. When the time is set using the dialogue above, the time entered in the Mervis IDE dialogue (be it the PC time or Custom time) is recalculated to the UTC time according to the time zone set in the PC, and this UTC time is written to the PLC. In the PLC Runtime, this UTC time is recalculated to local PLC time, which depends on the time zone setting in the PLC. Note:The PLC real time clock are working with UTC time (central world time). The fastest and easiest correction, mostly with sufficient accuracy.Ĭustom time: It is possible to set any time and write it to the PLC by clicking OK. Or: System status - Right click on UTC time - Time setup:Ĭomputer time: The PLC clock wil be set to the current time of the PC from which the setting is done. Right click to PLC - PLC Operation - PLC Setup - Time setup: However, it is advised to check the correct time when servicing the device: Time setting is thus not influenced by power outages. The Real Time Clock, RTC is backupped by a battery. The PLC has a real time clock which, among other things, is used to control weekly and exception schedules.
