Date and Time Library | S7-200 Smart | RTC

Write Date and Time :

You can also set PLC Date and Time via using above Block.
Note: You can't use WRITE and READ block simultaneously.

Check Validity for your Machine :

L_Date means the Last Date... When the current time crosses the last date and time, Expired output bit will turn on. you can use to set expiry date for your machines. 

Sharing is caring!
