Introduction

Telegram configuration and I/O addressing schematics
The I/O addresses of the NX and SINAMICS Integrated components for communication
between the NCU and the drive are entered in the TIA Portal and in the machine data of the
NCU.
In order that the I/O addresses match in the TIA Portal and in the machine data of the NCU,
they are identical by default and correspond to the standard I/O addressing schematic.
If you use the expanded I/O addressing schematic or have made user-specific adjustments
to the telegram configuration, you must synchronize these I/O addresses between TIA Portal
and machine data.
Note
Safety Integrated plus (F-PLC): Different I/O addresses for telegram 701 in NCU V4.7 (TIA
Portal) ad NCU ≥ V4.7 SP2 (machine data)
If you configure an NCU V4.7 (TIA Portal) but the firmware V4.7 SP2 (or higher) is used in
the actual hardware, the preset I/O addresses from the Siemens telegram 701 in the TIA
Portal do not match those in the machine data (MD10393).
• To establish compatibility with NCU firmware ≥ V4.7 SP2, you can adapt the I/O
addresses in the configuration.
See: Calling the telegram configuration (Page 111), Viewing I/O addresses in the TIA
Portal (Page 105), PROFIsafe/PROFIdrive telegrams for Safety Integrated plus (F-PLC)
(Page 130)
• Alternatively, you can adapt the I/O addresses in the machine data. In this case, your
telegram configuration is considered as user-defined telegram configuration.

Telegrams used by default
● Which telegrams are used by default depends on the SINUMERIK Safety Integrated
mode.
● Which I/O start addresses are assigned to the telegrams by default depends on the I/O
addressing schematic used.
● The Partner data area of a telegram (one each for actual value and setpoint) results from
the I/O start address and the telegram length in bytes (1 WORD = 2 bytes). The telegram
length depends on the telegram type used.
