Date/time

"Date/time" option
This is used to set the date, time and time zone for the HMI device.
Synchronizing date/time with the PLC
The date and time of the HMI device can be synchronized with the PLC, if this has been
configured in the project and the PLC program.. The two PLC jobs 14 ("Set time") and 15
("Set date") are provided for this.
PLC jobs 40 and 41 can be used to transfer the date and time from the HMI device to the
PLC.
Notice
Synchronize the date and time when time-controlled responses should be triggered in the
PLC by the HMI device.
The HMI device can only buffer the date and time for a few days if no power is supplied. If
the HMI device is not to be used for a number of days, it is recommended to synchronize the
date and time via the PLC.
Further information on this is available in the "WinCC flexible Communication" user manual.
