I am trying to get a handle on how to manipulate/interpret the following bits in a C0-11DRE-D running version 2.10: SC53: _RTC_Date_Change SC54: _RTC_Date_Change_Error SC55: _RTC_Time_Change SC56: _RTC_Time_Change_Error Specifically, I am trying to set the date and time from a EA9-T7CL running version 6.30. If for some reason I have invalid data in the following registers when I turn on SC53 or SC55 the respective error comes on as I would expect : SD29: _RTC_New_Year(4 digits) SD31: _RTC_New_Month SD32: _RTC_New_Day SD34: _RTC_New_Hour SD35: _RTC_New_Minute SD36: _RTC_New_Second However, I have no way to CLEAR THE ERROR. If I reset SC53/55 then subsequently set each of them it attempts the date/time change and will update the error bits accordingly. I have found the Help Topic: CL109 to be lacking these bits both in the version installed in CLICK 2.10 as well as the online (link attached) version. Is there any information available to give a clear description of these system bits/registers?

    Take a look at Help Topic CL194.

    Hey thanks!

    I thought that there was some published explanation, but did not find it.

    It would be nice for CL109/CL110 to indicate something about this - maybe a reference to CL194.

    Thanks mwdkmpr!

    This is exactly what I was looking for. I had assumed it would be included in the help topic that dealt with the other System registers.
