12-13
The value in Target Message Register 0112(hex) is 0x0037. 0x0037 = Decimal 55 - Link Error
Primary (As per format FC134)
Table 12-12: Format FC134 (See full description in Format Code Table)
For Target Index #2: GND IOC 1 Trip PKP
The value in Target Message Register 0111(hex) is 0x00C0. In the FC134 table below, this
corresponds to Trip.
The value in Target Message Register 0112(hex) is 0xF201. In the FC134 table below, F2
corresponds to IOC 1, and 01 corresponds to Pickup.
Table 12-13: Format FC134 Byte Assignments
For Target Index #3 - Last Trip: GND IOC 1 Trip OP
In this example, we see the GND IOC 1 Trip OP event logged as the last trip.
Las Trip Data Cause: GND IOC 1 Trip OPEvent Number: 768
Details about the Last Trip can be found in the Last Trip Modbus Registers:
Table 12-14: Modbus Map entries, Last Trip
Follow these steps to obtain information about the Last Trip:
1.
Read address 35190 (0x1445) to obtain the Last trip Data Cause. (32 bit).
2.
Read address 35192 (0x1447) to find the Event Number. (32 bit)
In this example, the value in Last Trip Cause Register 0x1445(hex) is x00C0. In the FC134
table below, this corresponds to Trip.
The value in Last Trip Cause Register 0x1446(hex) is 0xF202. In the FC134 table below, F2
corresponds to IOC 1, and 02 corresponds to Operate.
