Parameter: Enabled
For the declaration, data type, range of values, default and function, refer to
the section Reoccurring parameters (Page 144).
Typical-
specific re-
sponse:
Enable block processing
If processing is disabled the FB only checks to see if the disabled status has
been canceled. The block cannot communicate at the organizational level in
this status because it cannot send any Org. frames.

Explanation:
Command input byte for hardware input.
This command input byte is specially designed for entering commands using
hardware, i.e. via digital inputs. Input using memory or data bytes is also pos-
sible, but you must then make sure that the command pending at the input
byte is reset, which occurs during hardware input when the command button
is released.
When input is detected, if no error is detected during the 1-out-of-8 and 1-out-
of-n check, and if the central enable memory bit is set, the command is trans-
ferred. This is automatically set by FC Safe following a selected time delay set
there (see FC Safe, "InputDelayTime" parameter).
If a 1-out-of-8 or 1-out-of-n error is detected, the entered command is no
longer processed. A new command is only read in again if previously for the
time of one OB1 cycle no hardware command was detected in the CPU at this
or another command input block with a hardware input.
The FB enters a detected 1- out-of-8- or 1-out-of-n error in the diagnostic buff-
er (event ID B171 or B172). The error status is also indicated via the "InputEr-
ror" output of FC Safe (see FC Safe, "InputError" parameter) and continues to
be indicated as long as the error remains.
