Adapting I/O start addresses

6.8.1

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.
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.
