8.11 Digital inputs/outputs
Cable specification
For PROFINET, you always require a data transmission rate of 100 Mbit/s (Fast Ethernet) in full
duplex mode. For data transfer purposes, you can use twisted-pair copper cables (4-wire,
100Base-T).

Connecting sensors and actuators
Digital inputs and outputs can be used to connect various sensors and actuators to the 2x7-pole
connectors X142/X152 on the front panel.
The following types of digital I/O are used:
● Digital inputs (isolated)
● Digital outputs (electrically isolated)
● Bidirectional digital inputs/outputs (only for drive terminals)
The assignment of I/Os to functions can be parameterized freely by the user.
The enable signals for the drive units and/or motors (Line Module, Motor Module) connected to
the MCU can be switched using the digital inputs.
Note
Terminal assignments
When commissioning the drive wizard, the digital inputs/outputs are correspondingly
preassigned functions.
For more information about terminal assignment, see:
● Commissioning Manual "IBN CNC: NCK, PLC, drive", Chapter "Communication interfaces
and terminal assignment"
● "Guidelines for machine configuration" System Manual, Chapter "Interfaces and their
terminal assignment"
