Interconnection via PZD
In principle, an assignment via the PZD is also possible (e.g. via DI_0_15 or DO_0_15). Note
that for these signals a message frame of the appropriate length is generated, but the BICO
interconnection is not performed.
For this purpose, switch to the "Communication" dialog box of the corresponding SINAMICS
DO. You can now see the individual bits of the PZD (e.g. I_Digital or O_Digital) listed there.
Interconnect the appropriate bit of the PZD with a signal.
Alternatively, you can assign SIMOTION to an I/O channel during the terminal configuration
(e.g. by selecting "DI (SIMOTION)", see Section Configuration of the D4x5-2 I/Os (terminal
X122/X132) (Page 258)).
TO axis
The symbolic assignment of I/Os is also supported by the TO axis (e.g. for a HW limit
switch).
Substitute values for I/O variables
Substitute values cannot be specified for input variables of the BOOL data type. If you do
require substitute values however, proceed as follows:
1. Assign a digital input (e.g. SINAMICS_Integrated.Control_Unit.DI_0 [DI 0, X122.1]) to an
2. Create a global variable (e.g. all_inputs) (at least data type WORD, e.g.
3. Configure the substitute value.
For various SINAMICS drive objects, higher-level types are available for the assignment of
substitute values.

input variable of the BOOL type (e.g. sensor).
SINAMICS_Integrated.Control_Unit.DI_0_15).
The appropriate bit of the substitute value must then contain the substitute value for the
BOOL variable.
In the same way, you can assign a substitute value to a BICO parameter.
