Inputs_DFOUT / Outputs_DFOUT
This SB converts internal speed signals into frequency signals and outputs them to X8
(configuration via C0491).
ƒ
Transmission is effected with high precision (without offset and amplification
faults) including remainder considered.
ƒ
The type of output signals can be set via C0540.
ƒ
A configuration of the master frequency output X8 as input (

Note!
The process image is recreated for every task the SB is used in.
ƒ
If therefore DFOUT_nIn_v and DFOUT_nOut_v are used in several tasks, an
individual process image of the SB is created for each of these tasks.
ƒ
This process is different from the previous process image principle!
