3.2.85 ROT_ - Retentive On Timer

ROT_ function blocks perform an on-delay timing
function with output states determined by inputs ON and
EN.
When input EN is low (0) outputs D and ND are low and
when input EN is high (1), the outputs will be determined
by the ON input and the elapsed time.
When ON goes high the elapsed time will start. Output D
will go high after ET (elapsed time) equals or exceeds the
DLY TIME. Output RT (remaining time) equals DLY
TIME - ET. If ON goes low, the elapsed time will stop at
the current value and will continue when ON returns to a
high state. The elapsed time returns to 0.0 when input EN
goes low. Output ND will be high (1) if input EN is high

3.2.86 ROUT_ - Relay Outputs

ROUT_ function blocks provide SPDT contacts activated
by function block input C. The relay will turn on when the
block input is high (1) and will turn off when low (0).
Two relay outputs are available on the Expander Board.

YES, the block will initialize at the input/output states and
elapsed time at the instant power down occurred. A cold start
will initialize the input/output states and elapsed time to 0.
