5.3.4 Device name and IP address at delivery
In a Profinet network it is mandatory that each IO device is provided
with its own Device name and IP address. By default, before delivery
the device name of the encoder is set to a blank string and its IP
address is set to 0.0.0.0.. When the system boots up, the IO
controller assigns the IP address to the IO device. Please make sure
that the Assign IP address via IO controller check box in the
Properties dialog box is selected if the IP address has to be assigned
to the encoder via the IO controller. Anyway the assignment of the IP
Address can be disabled by deselecting the Assign IP address via IO
controller check box. In this case the IP address set in the IO device
is used (the IP address is uploaded from the internal memory). You
are required to enter the Device name first and then the IP address.
5.3.5 Setting the device name
Before the PROFINET IO controller can address a PROFINET IO
device, a name has to be assigned to the PROFINET IO device.
PROFINET uses this method because names are easier to use and
recall than complex IP addresses. Devices on an Ethernet subnet
must have unique names.
NOTE
An IO Device does not have a device name when delivered. By
default, the device name of Datalogic's Profinet encoders is set to a
blank string.
The device names must satisfy DNS (Domain Name System)
conventions:
Names are limited to a total of 127 characters (letters,
numbers, dashes or dots).
Any component part (that is, a character string between two
dots) of the device name may only be up to 63 characters
long.
Names cannot contain any special character such as umlauts,
parentheses, underscores, forward or backward slashes,
empty spaces, etc. The dash is the only special character
allowed.
Names must neither start nor end with the minus "-" sign.
There are a couple of ways to assign the device name to the
encoder.
The steps are described in the following tables.
