Hi

My HMI screen wont show the same time as my PG/PC time. The HMI is always 1 hour behind the actual time in my timezone. Why could this be?

HMI is also 1 hour behind when i uncheck the PG/PC box and manualy set the time.

Hi,

are you using time synchronization?

Maybe time server and HMI have different time zones.

Hello,

Keep HMI, PLC time zone same.

There may be different time zones for both.

In case of time synchronization check block used whether it is local for local time or system time.

Hi,

Yes im using time synchronization in the program. The HMI is set as a slave.

How can i set the time for the HMI if i disable time synchronization?

Hi,

on the panel go to Control Panel. There you find date and time settings where you can adjust the time resp. time zone.

Hi,

When i have unchecked the master/slave field for the HMI and set its own time, will the date/time fields put into a HMI program show the HMI date/time? Or will the HMI date/time field in the program show date/time of the PLC CPU? Also is this the same for the HMI alarm window date/time?

when you select System Time for the IO field, then it shows the time of the HMI and it is the same time in the alarm view.
