CLOCK Picture (Setting the Real Time Clock)
The date and time of the internal real time
clock can be set in this picture. By pressing
keys on the Panel, the date and the time are
entered in input fields on the Panel display.
The real time clock however, is only set
when function key F1 (SET HH/MM/SS) or
F2 (SET MM/DD/YYYY) is pressed.
To set the real time clock on the PANELWARE Panel, internal variables are used. The following
table lists these variables and their functions:
Variable name Data type Description
DATE_YY_S Word unsigned Year (Format 19xx)
DATE_MM_S Byte unsigned Month
DATE_DD_S Byte unsigned Day
TIME_HH_S Byte unsigned Hours
TIME_MM_S Byte unsigned Minutes
TIME_SS_S Byte unsigned Seconds
DATE_SET Byte unsigned By writing a non-zero value to this variable, the date of the
real time clock is overwritten with the values of variables
DATE_YY_S, DATE_MM_S and DATE_DD_S.
TIME_SET Byte unsigned By writing a non-zero value to this variable, the real t ime
clock is overwritten with the values of variables
TIME_HH_S, TIME_MM_S and TIME_SS_S.
The input fields are scaled, limiting the entry to a valid range for time and date values. Date and
time are set through key functions.
