Micrologix 1200 Clock Functions

Hello, Is there a way to control this PLC clock? Beyond the RTA function, it doesn't appear that one can actually programmatically set the clock. I've tried to write to both the S:37-S:42 and RTC:0.XXX parameters and have ran out of ideas...

Thanks for your help.

i met the same question.someone said we don't have the RTC modle

Look at the Micrologix reference manual. 1762-rm001. It says these addresses are read only but it also talks about syncing the time between 2 controllers with messaging.
