Table 1, Table 2, Table 3, and Table 4 describe Totalization Migration. The totalization is not deleted in the NCM and continues to run. If the totalization is modified in either the Metasys N1 Network system or Metasys system system, the changes are not reflected in the other system. The migration occurs only on Metasys system object addition.

Table 1 depicts the migration of an Analog Totalization. Table 2 depicts the migration of an Event Totalization. Table 3 depicts the migration of a Pulse Totalization, and Table 4 depicts the migration of a Runtime Totalization.
