UM353-1 Function Blocks
March 2003 3-93
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
and output D is not high. With firmware 1.30 and higher,
the DLY TIME is adjustable over the full range of the display
which is 0.00000 to 999999. In earlier versions, the minimum
time setting was 0.1. If the delay time is set to less than the
scan time of the station the delay time will equal the scan
time.
POWER UP - During a warm start, when PU LAST is set to
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.
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.
Terminal Connections are listed in Section 8.4.
