Function Blocks

3.2.87 RSF_ - RS Flip-Flop

RSF_ function blocks perform a reset dominant flip-flop
function as detailed in the truth table. An unused S input
will be set high (1) and an unused R input will be set low
(0).

3.2.88 RTG_ - Rising Edge Trigger

RTG_ function blocks provide a high (1) output for one scan
cycle each time input P transitions from a low (0) to a high
(1).

3.2.89 RTT_ - Real Time clock Trip (V2.0)

RTT_ function blocks provide high (1) outputs when time
from the CLOCK block coincides with the TIME, DATE, &
DAYS of the Week TRIP settings. The block outputs will
remain high while the CLOCK coincides with the settings
