7 Special functions
7.1.3.2 Wiring
Note
Always observe the maximum capacity of the output (see Pin assignment).
The outputs are implemented as open drain. Hence, an external voltage supply is always necessary.
Example
The digital output signal should continue to be used. For this purpose, a circuit as shown in
the following figure is to be realized.

is recommended.
Example
A simple load is to be used with the digital output.

7.1.3.3 Object entries
Additional OD entries are available for manipulating the value of the outputs (see the following example
for further information). As with the inputs, only the bit at the corresponding location acts on the respective
output:
●
3250
h
:01
h
: No function.
●
3250
h
:02
h
: This is used to switch the logic from normally open to normally closed. Configured as normally
open, the input outputs a logical high level if the bit is "1". With the normally closed configuration, a logical
low level is output accordingly for a "1" in object 60FE
h
.
●
3250
h
:03
h
: If a bit is set here, the output is controlled manually. The value for the output is then in object
3250
h
:4
h
; this is also possible for the brake output.
●
3250
h
:04
h
: The bits in this object specify the output value that is to be applied at the output if manual
control of the output is activated by means of object 3250
h
:03
h
.
