The Metasys system reads the Metasys N1 Network calendar to generate two calendar objects.
The Metasys N1 Network calendar lists alternate and holiday dates for a year, starting with the current system month. For example, if the current month is September 2017, the calendar contains entries from September 1, 2017, until August 31, 2018.
The Metasys system calendars are created under the N1 Migration object and named Alternate and Holidays. These calendars contain the following:
Alternate - Contains all days marked as Alternate days in the selected Metasys N1 Network calendar.
Holiday - Contains all days marked as Holiday days in the selected Metasys N1 Network calendar.
When a change is made in a Metasys N1 Network calendar, the corresponding calendars in the Metasys system are updated. When a change is made in either of the Metasys system N1 calendars, the changes are written to the Metasys N1 Network calendar. If you delete either calendar, the Integration object adds it again. This feature ensures that the operator continues to have access to the Metasys N1 Network calendar. The Metasys N1 Calendar attributes are identical to the Johnson Controls Calendar object. You cannot enter dates more than one year beyond the current month.
