4.2.9 Breaker control
The L90 can interface with associated circuit breakers. In many cases the application monitors the state of the breaker,
that can be presented on front panel LEDs, along with a breaker trouble indication. Breaker operations can be manually
initiated from the front panel keypad or automatically initiated from a FlexLogic operand. A setting is provided to assign
names to each breaker; this user-assigned name is for the display of related flash messages. These features are provided
for two breakers; the user can use only those portions of the design relevant to a single breaker, which must be breaker 1.
It is assumed in the following discussion that the
