A counter instruction is an __________ .
Consider 2 statements

Statement 2 - The counter will retain the ON or OFF status of done bit ,overflow bit and underflow bits through a power loss.
Statement 1 - The counter will retain its accumulated value through a power loss.
Statement 2 - The counter will retain the ON or OFF status of done bit ,overflow bit and underflow bits through a power loss.
Everytime the count-up instruction sees a false-to-true rung transition, a count-up counter‘s accumulated value is _______.
For a count-up counter, in the event of wrap from +32,767 to -32,768, the accumulated value becomes less than the preset value and the done bit will ___________.
In the word zero, of the counter element, _______ bit is set when the accumulated value of a count-up counter has reached the highest possible accumulated value, which is +32,767. At This point, the counter will automatically wrap around and start counting up from the maximum negative value -32,768.
In default counter file, how to address the counter’s 16 accumulated value?
_________ is the current (r.m.s value) that a Circuit breaker is capable of breaking under specified conditions and given recovery voltage.
