Totalizations - Metasys - LIT-1201535 - Supervisory Device

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.

Table 1. Analog Totalization Migration
Metasys System Analog Totalization Object Configuration Attribute Name/Type	Metasys N1 Network Analog Totalization Configuration Variable/Type	Notes
Input_Reference/Structure	\system\object\attr_name/char[ ]	Convert to reference (match as best you can the attribute number).
Rollover Limit/Double	limit/Float
Units/Enumeration	display_units/char[7]	Match the Metasys N1 Network unit as best you can.
Low_Cutoff_Value/Float	low_cutoff/Float
TimeBase/Enumeration	time_scale/Float
ScaleFactor/Float	display_scale/Float
RollOver/Boolean	TRUE
Present Value		Read current Totalization value from Metasys N1 Network and set.
Add Analog Alarm object	Report type	Is Crit1-4 or status
FAULT_ACK_REQUIRED_ATTR	Report type	If Crit1, 2, 3, or 4, set Metasys system attribute to True in analog alarm object.
Alarm Message text	ALARM_MSG_#	Read Metasys N1 Network text from the number and save in alarm object.

Note: The Metasys N1 Network period parameter is not mappable to Metasys system totalization.

Present Value		Read current Totalization value from Metasys N1 Network and set.
Add Analog Alarm object	Report type	Is Crit1-4 or status
FAULT_ACK_REQUIRED_ATTR	Report type	If Crit1, 2, 3, or 4, set Metasys system attribute to True in analog alarm object.
Alarm Message text	ALARM_MSG_#	Read Metasys N1 Network text from the number and save in alarm object.

Note: The Metasys N1 Network period parameter is not mappable to Metasys system totalization.

Add Analog Alarm object	Report type	Is Crit1-4 or status
FAULT_ACK_REQUIRED_ATTR	Report type	If Crit1, 2, 3, or 4, set Metasys system attribute to True in analog alarm object.
Alarm Message text	ALARM_MSG_#	Read Metasys N1 Network text from the number and save in alarm object.

Note: The Metasys N1 Network period parameter is not mappable to Metasys system totalization.

Table 4. Runtime Totalization Migration
Metasys System Event Totalization Object Configuration Attribute Name/Type	Metasys N1 Network Runtime Totalization Configuration Variable/Type	Notes
