Configuring an I/O variable

Overview
You have two ways to assign an I/O variable to I/O terminals:
● Assignment via preferred interconnection (e.g. DI_8 [DI/DO 8, X121.7])
To do this, you must use the SIMOTION preferred interconnection for the corresponding
input/outputs of the SINAMICS DOs. The BICO interconnection is performed automatically.
● Assignment via PZD (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.
Interconnection via preferred interconnection
The I/O variables are configured via the address list. Components that support a symbolic
assignment can be configured without I/O addresses.
Preferred interconnections are displayed as assignment targets in the Assignment dialog box
(e.g. DI_8 [DI/DO 8, X127.7]). The assignment is made by direct selection of the corresponding
terminal signal.
Components that do not support symbolic assignment (e.g. standard PROFIBUS I/O) are
configured via I/O addresses.

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.
