Sequence 4 (LatchedAck-S-F)
SEMOD56072-64 v1
This sequence has the same functionality as sequence 3, but steady and flashing light
have been alternated.
Sequence 5
LatchedColl-S
SEMOD56072-67 v4
This sequence has a latched function and works in collecting mode. At the activation of
the input signal, the indication will light up with a steady light. The difference to
sequence 3 and 4 is that indications that are still activated will not be affected by the
reset that is, immediately after the positive edge of the reset has been executed a new
reading and storing of active signals is performed. Every LED is independent of the
other LEDs in its operation.
