Status words are process data as defined by the explanation in Section
"Process data".
A "destination" at which the bit status can be identified (digital outputs
of CUSA, SCI 1/2 terminals, TSY terminals) can be parameterized for
each bit in a status word.
One parameter is available for "wiring up" the destination for each
status bit.
As shown below, the selection parameters have three indices:
Index i001 Selection of a terminal on the CUSA / PEU board
(basic unit)
Index i002 Selection of a terminal on the SCI 1/2 board (option)
Index i003 Selection of a terminal on the TSY board (option)
The message "motor operation" (status word 1, bit 14) must be "wired
up" to digital output 3 (BA3) on the CUSA (terminal X102:29/33) as a
high-active signal:
♦ "Wiring" of a status bit to a digital output on the CUSA is
parameterized via index i001.
♦ The table for status word 1 indicates that the message "Motor
operation" is assigned to parameter P614.
♦ Look for the parameter value for the desired destination in the same
table. The result is 1003 for digital output 3 on the CU.
This parameter value must now be set in parameter P614.1.

P614.1
When a High signal is applied to terminal -X102:29/33, the AFE
operates in generator mode and, in the case of a Low signal, in motor
mode.
If a value assigned to a terminal (digital output BA) is allocated to a
destination once in a selection parameter, then it will not be available in
the same index of any other selection parameter as a terminal is only
suitable for the output of one status
Faults, alarms and starting lockout (HIGH active) are displayed as
LOW active via the terminal strip (digital outputs).
This also applies to any option boards!
See Section "Digital outputs".
