FET Ch. - 1 indicates that the FET control signal line is high
7
.
RLY Ch. - 1 indicates that the relay control signal line is high.
FET CP - 1 indicates that the FET clock signal line is high.
RLY CP - 1 indicates that the relay clock signal line is high.
Fault Led - 1 indicates that the SIIM interface board fault LED is ON

.
A.5. Breaker Array
The breaker array consists of ten repeating groups of fields, each breaker being represented
by the following data:
The breaker status has the following format:
7
The FET and RLY channel and clock signal lines are high by default.
8
The fault LED is turned on whenever a breaker is tripped by the sub-sea controller software due to a
breaker limit being exceeded.
9
During normal operation this bit is toggled at 1 Hz.
