N.B. : - The disturbance data pages contain values of one channel
from one given disturbance record.
- significance of the value according to the type of channel :
V
A, VB, VC = 16 bits values
Frequency = time between 2 samples in ms
Logical channel =
bit 0 = RL1 ( Trip Relay )
bit 1 = RL2
bit 2 = RL3
bit 3 = RL4
bit 4 = watchdog
bit 5 = RL5
bit 6 = RL6
bit 7 = RL7
bit 8 = RL8
bit 9 = reserved
bit 10 = logic input 1
bit 11 = logic input 2
bit 12 = logic input 3
bit 13 = logic input 4
bit 14 = logic input 5
bit 15 = reserved
