(2) Calendar Status
The relationship between the CNC calendar data and a parameter setting is indicated below.
Since the calendar data treated as binary data, comparison is possible even if the month value
exceeds “12”or day value exceeds “31”.
For example, if the setting for a parameter is “19999999”, and if the CNC calendar data is
“19960715” (July 15,1996), comparison is made as indicated below.
19960715 - 19999999
Since the result of comparison is negative, the output is “0” (status of the calendar).
To clear the calendar status, reset an appropriate value for a calendar parameter. When a
value greater than the CNC calendar data is et, the status of the calendar is cleared.
The parameters used as the calendar parameter are indicated below.
