Application Module FM 458 - User Manual
6DD1904-0AE0 Edition 12.2001
LED displays H1 to H8, when required, can be controlled using
function block BIQ8 (digital output).
LEDs H9 and H10 have no function.
The LE bus ensures fast data transfer between the FM 458 application
module and its expansion modules EXM 438/EXM 438-1/EXM 448.
The peripheral bus (P bus) is the parallel SIMATIC backplane bus,
which only provides the power supply for the EXM 438.
