The function block, which controls the FM 458-1 DP diagnostic LEDs,
can only run with an FM 458-1 DP application module.
The LEDs of the FM 458-1 DP application module can be controlled
using this block.
The LED display is canceled for a value of 0 at the appropriate input; for
a value of 1, it is set and for a value of -1, its status is retained,
unchanged. The value of -1 is required, as this block has been configured
a multiple number of times.
Output QF has the value 1, if the inputs have invalid values, or if the
block is not configured on the FM 458-1 DP application module.
