The Bus I/O In Bits are perceived as digital inputs. They can be set to the same functions
(P420).
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 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).

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.

Hysteresis of bus I/O Out bits
S
1 … 100 %
{ all 10 }
Difference between switch-on and switch-off point to prevent oscillation of the output signal.
