Figure 51: 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
LED following the signal and reset, when no higher prior signal is given.
The LED illuminates always in steady mode.
