8.3 Software Configuration
PROFINET is an open standard for industrial automation based on industrial Ethernet. PROF-
INET integrates information technology with established standards such as TCP/IP and XML in
automation technology.
Within PROFINET, PROFINET IO is the communication concept for the construction of decen-
tralized applications. This means that read heads are integrated through PROFINET IO. The
familiar IO view of PROFIBUS DP is used where the usable data of the read heads is trans-
ferred to the process image of the control panel in cycles. PROFINET IO is a device model con-
sisting of slots and channels, which is based on the main features of PROFIBUS DP. The
properties of the read heads are written in a Generic Station Description Markup Language
(GSDML) based on XML. PROFINET IO is engineered in such a way that the read heads are
assigned to a control panel in project planning.
PROFINET IO distinguishes between the following three device types:
• IO controller: Controller that executes the automation program.
• IO device: Decentrally assigned field device that is assigned to an IO controller.
• IO supervisor: Programming unit/PC with commissioning and diagnostic functions.
The read head functions as a PROFINET I/O device that communicates cyclically with the
assigned PROFINET I/O controller during operation.
Project planning using device description
The read head is integrated into the project planning tool by way of a device description. The
field device properties are described in the GSDML file. The GSDML file contains the data of
the field device that you need to operate the device in a PROFINET network. You import the
GSDML file into a project planning tool that you use to configure the read head settings. Once
project planning is complete, the control panel receives the project planning data and configu-
ration data.
Downloading the GSDML file
You can find the relevant GSDML file in the Software section of the product detail page for the
device.
To access the product detail page for the device, go to http://www.pepperl-fuchs.com and type
e.g., the product description or the item number into the search function.
PROFINET address and identifying a device
Every read head has a unique device identification. This device identification consists of the fol-
lowing:
• A unique MAC address. This MAC address is printed on the back of the device.
• A device name. The default device name is wcs3b-ls610.
• An IP address. The default IP address is 192.168.2.2.
