Circuit Breaker Manager Event Log

The system stores the events that concern circuit breaker control (for example opening or closing of the contacts) in the file number 30.

This file is made up of 100 records and each record is made up of five registers.

This file is reset in case of 24 Vdc power loss on the BCM ULP module or change of the communication parameter 4W/2W + ULP.

The following table describes the file header content:

Address	Register	RW	X	Unit	Type	Range	A/E/P	Description
0x02CD	718	R	–	–	INT16U	–	A/E/P	File status: 0x0000 = file disabled 0xFFFF = file enabled (factory setting)
0x02CE	719	R	–	–	INT16U	–	A/E/P	Type of file = 30
0x02CF	720	R	–	–	INT16U	–	A/E/P	File allocation = 0xFFFF
0x02D0	721	R	1	–	INT16U	–	A/E/P	Size of a record = 5 registers
0x02D1	722	R	–	–	INT16U	–	A/E/P	File filling mode: 0 = circular

The following table describes the file status content:

Address	Register	RW	X	Unit	Type	Range	A/E/P	Description
0x02DD	734	R	1	–	INT16U	100	A/E/P	Size of a file = 100 records
0x02DE	735	R	1	–	INT16U	5	A/E/P	Size of a record = 5 registers
0x02E0	737	R	1	–	INT16U	0–100	A/E/P	Number of records in the file
0x02E1	738	R	1	–	INT16U	0–8000	A/E/P	Sequence number of first record in the file (the oldest)
0x02E2	739	R	1	–	INT16U	0–8000	A/E/P	Sequence number of last record in the file (the most recent)
0x02E3– 0x02E5	740–742	R	–	–	DATE	–	P	Date of the last file reset Factory setting = 0x8000 0x8000 0x8000

The following table shows the format of 1 record in the event log of the circuit breaker:
