Figure 50: 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
following the signal and reset, when no higher prior signal is given.
The LED illuminates always in steady mode.
