Different from decoding the operation number to find out event type as in DPR2000R,
REF615R reads the Modbus addresses associated with the event.
In one case, for example, the operation record has the following readings as shown in
Table 22.

User needs to check "Feeder Protection and Control REF615R Modbus Point List
Manual", document ID: 1MRS240052-IB to find out 10513 is mapped to IEC61850 path
of "CTRL.CBCSWI1.PosOpn.stVal" and its description is "52-1 Apparatus open
position", and understands value of 1 means "breaker open" as status value is set as 1.
By default, some Modbus registers do not generate event upon value changes. To make
them generate events, user can use PCM600 / CMT tool to enable event from "rising edge"
or "both edge" of the signal's status change. On the other hand, user can disable generate
default event from PCM6000 / CMT by simply checking off the event enable bit as shown
in Figure 6.

1 Area of the Register on which the event happened (0 = coil; 1=
input, 4 = 4x)
1 Register address on which the event happened
values meaning
0 Higher word value is 0
1 Lower word value is 1
1 Register area is 1, it is a 1x register
513 Register address is 513
