Function Bus I/O Out bits
0 ... 39
{ all 0 }
The bus I/O Out bits are perceived as multi-function relay outputs. They can be set to the same
functions (P434).
These I/O bits can also be used in combination with the AS Interface (SK 225E or SK 235E) or
the I/O extension (SK CU4-IOE or SK TU4-IOE).

The possible functions for the Bus Out Bits can be found in the table of functions for the relay
P434.

Standardisation of bus I/O Out bits
-400 … 400 %
{ all 100 }
Adjustment of the limit values of the bus Out bits. For a negative value, the output function will
be output negative.
Once the limit value is reached and positive values are delivered, the output produces a High
signal, for negative setting values a Low signal.
