12 PROFINET

If we are speaking of PROFINET, then the 100 Mb/s-version is meant, full-duplex and switched
Ethernet. The end device's protocol is being converted in the UNIGATE
®
The UNIGATE supports PROFINET I/O-RT.
12.1

Data exchange mode

The Gateway has to be in the data exchange mode, so that a data exchange between the RS-
side of the Gateway and the Fieldbus is possible. This mode is always avtive as long as the gate-
way is not in the configuration mode, the firmware update- or Debugmode. In the data exchange
mode the gateway will carry out the downloaded Script.
12.2

PROFINET address-assignment

Note: on delivery, the Gateway has no IP address! 
During normal operation (data exchange mode) the IP-address is assigned to the gateway by the
PROFINET-IO-controller (PLC). For it the gateway has a device name (more details in chapter
12.3). The IP address can be assigned manually or via a DHCP server.
12.3

PROFINET device name

Note: on delivery, the Gateway has no device name!
The device name is assigned via the configuration software of the Gateway. Alternatively the
device name can be changed via the FTP (file „devname.txt") or via Script.
Accordingly to the PROFINET specification, the following rules apply to the device name:
• It consists of one or more name parts seperated through a full stop
• the total length is from 1 up to 240 characters
• the length of a part of the name is 1 up to 63 characters
• a name consists only of lowercase letters, number and the hyphen
• the first part of the name does not begin with „port-xyz" or „port-xyz-abcde", whereas a, b,
c, d, e, x, y and z are seen as numerals
• it doesn't have the form „k, l, m, n", whereas k, l m and n are numbers between 0 and 999
12.4

Projecting

Use any project planning tool for project planning.
A sample GSD-file (that is based on the XML-oriented standard GSDML) can be found on the
Internet (www.deutschmann.com) free of charge. Generating the GSD-file is also provided as
service from Deutschmann Automation.
