Preparing the CFU for commissioning

8.5.1

Rules for device names

A CFU must have a device name so that an IO controller can address the CFU as an IO device.
This approach was chosen for PROFINET because names are easier to understand than
complex IP addresses.
The device name must be unique in the PROFINET IO system.
The assignment of a device name for the CFU corresponds to the setting of the PROFIBUS
address for a DP slave.
Rules for specifying the device name (in accordance with IEC 61158-6-10)
● A device name may have a maximum length of 240 characters (letters, numbers, hyphen
or dot).
● A device name must consist of at least one character.
