Trip History

General Description

The trip history registers describe the last 17 encountered trips. The trip history format corresponds to a series of 17 records. Each record is composed of 7 registers describing one trip.

The trip history registers return 32768 (0x8000) when they are not used.

Trip Record Number

A read request of 7x(n) registers is necessary to read the last n trip records, where 7 is the number of registers for each trip record.

For example, a read request of 7 x 4 = 28 registers is necessary to read the last 4 trip records of the trip history:

The first 7 registers describe the first trip record (most recent trip).
The next 7 registers describe the second trip record.
The last 7 registers describe the third trip record.
The last 7 registers describe the fourth trip record.

Trip Record

A read request of 7 registers is necessary to read a trip record.

The order and the description of the trip record registers are the same as that of the trip record 1:

Trip Record 1 (Most Recent Trip)
Address	Register	RW	X	Unit	Type	Range	A/E	Description
0x238B	9100	R	1	–	INT16U	0–65535	A/E	Trip code (see next paragraph)
0x238C– 0x238E	9101– 9103	R	–	–	ULP DATE	–	A/E	Date and time of event (trip or acknowledge. Data Type: ULP DATE
0x238F	9104	R	1	–	INT16U	1–2	A/E	Event type MSB = 0 (reserved) Event occurrence: LSB = 1 Event completion: LSB = 2
0x2390	9105	R	1	–	INT16U	0–5	A/E	Faulty phase 0 = failure (no faulty phase) 1 = phase 1 2 = phase 2 3 = phase 3 4 = phase N 5 = phase 1 2 3 (motor application, ground-fault, earth-leakage)
0x2391	9106	R	1	A	INT16U	0–65535	A/E	Interrupted current (peak) ⁽¹⁾
(1) Measurement depends on the application: For electrical distribution application, the interrupted current is measured when a trip occurs, due to the long-time protection, the short-time protection, or the instantaneous protection. For motor-feeder application, the interrupted current is measured when a trip occurs, due to the short-time protection. In case of other trip types, the interrupted current is not measured and the value recorded is 65535 (0xFFFF).
