LED operation mode LatchedAck-S-F
This operation mode operates exactly as the one described above (LatchedAck-F-
S). The only difference is that the illumination mode is changed. Flash mode
instead of steady mode and steady mode instead of flash mode.

LHMI: LED operation mode LatchedColl-S
This mode catches a signal change to
ON
and the LED stays
ON
until the operator
resets the LEDs for this group.
If the signal is still
ON
when a reset LED is done, the LED will illuminate again.
This occurs when the application configuration accesses the signal again in the next
cycle after reset. The thin dashed lines in
shows the internal state of the
LED following the signal and reset, when no higher prior signal is given.
The LED illuminates always in steady mode.
