Hi everyone,

I have got a problem between PLC and Touch Panel, the problem is that I want to change the hour in the Touch Pannel but when I set up the new hour, it does not change, it carry on being the same hour and date.

Could be it due that from the Touch Pannel only can read and from the PLC you may read/write?

I need a solution as soon as possible.

PLC: 300

Touch Panel: KTP

Thank you in advance

Hello lacuna23,

Have you seen this link:

Clock synchronization between a HMI operator panel and a SIMATIC PLC

It is possible to change time by using HMI panel. After you have changed it, you should Set (write) realtime clock of CPU.

Best regards,
