how to generate Real time clock in S7 plc.

Hi there,

The S7 PLC range already has a clock - you can access this in your code with the relevant SFC/FC.

Are you trying to write software to emulate a clock (part of the Siemens course)?

Or are you trying to synchronise the time of the PLC clock to your network?

Or are you looking to use the PLC time within your user program?

Please provide more information and we might be able to give you a better answer?

Regards

Craig
