Identifiers of monitoring objects

Unique identifiers (ID) for elements, groups and modules are issued from special ranges and by special formulas.

The System element that reflects the state of the system has a special identifier with a fixed value of ID = 100.

The identifiers of the system modules are issued from the range 2001 to 2999. The numbers are assigned in ascending order, in the order of initialization of the modules when the system boots. After saving the configuration, the IDs are restored from the configuration file.

The group IDs are issued from the range 3001 to 3999. The numbers are assigned in ascending order, in order of creating the groups. When deleting a group, the number is released and assigned to the newly created group.

The identifiers of the elements are calculated from the class and type of the element, and represent a six-digit number, where:

3	0	4	0	0	1
element class	element type		element number

The element class is encoded with one of the following numbers:

Code	Class description
1	sensors with digital output
2	sensors with analog output
3	switching elements
4	hardware devices: modems, readers and so on.
5	virtual devices: timers, pings and so on.
6	notifications: e-mail, sms and so on.

The element type is encoded according to the class:

Code	Sensors with digital output	Sensors with analog output	Switching elements	Hardware devices	Virtual devices	Notifications
01	dry contact	temperature sensor	relay	iButton reader	timer	e-mail notification
02	access sensor	humidty sensor	outlet	IP camera	ping	notification to the SNMP manager
03	airflow sensors	voltage sensor	switch	USB camera	logic scheme	SMS notification
04	motion sensor	transducer voltage sensor	low-current low-voltage output	GSM modem	trigger, virtual switch
05	vibration sensor	current sensor			SNMP virtual element
06	smoke sensor	Current Transformer
07	leakage sensor	vibration sensor
08	button (не используется)	energy parameter: power
09	overcurrent indication	energy parameter: frequency
10		other energy parameters

The element number is assigned in ascending order, in the order of initialization (if created by the system) or creation (if created by the user). When a member is deleted by the user (for those elements where this is possible), the number is freed and assigned to the newly created element of the given class and type.
