1 • INTRODUCTION
The “GFW adv” series of modular power controllers with PROFINET Fieldbus interface is designed for rapid integration of a large quantity of compact control units for temperature regulation and heating device control, within sophisticated automation systems (such as PLC, Supervisory Systems, etc.) interconnected via communication networks and
protocols dened by the standard.
This manual is not designed to describe the “PROFINET” Fieldbus, as it is presumed the user is familiar with the same
and will refer if any updates are required to the above-mentioned standard or the ofcial PROFIBUS CONSORTIUM and PROFINET International website (PI), http://www.probus.com/.
It is also presumed that the user is already familiar with the technical characteristics of GFW products, as described in the dedicated user manuals accompanying each product, or available for download from the GEFRAN S.P.A. website. www.gefran.com.
This user's manual will refer to GFW version in 2 variables dened as in ordination code E4/E6:
- E4 - Specic 2.2 - Stack 3.4.26.1 - Card ETH4 with Netx50
- E6 - Specic 2.3 - Stack 3.12.0.5 - Card ETH6 with Netx51
FEATURE NEW PROFINET (stack PROFINET specica 2.3) COMPARED TO OLD E4 (stack PROFINET specica
2.2)
FUNCTION DESCRIPTION
Media Redundancy Protocol
client di tipo Bumpless
Lets get:
- a time of zero reorganization of the network
- no isochronous frames lost In case of interruption of the PROFINET communication
loop
Fast Forwarding It allows a reduction of the transit delay of the PROFINET package through each
node of 50%
Dynamic Frame Packaging It allows to optimize the bandwidth, and to arrive at a theoretical cycle time for IRT
trafc equal to 32.5us instead of 1ms

4 • OVERALL COMMUNICATION ARCHITECTURE
The communication structure implemented in the GFW communication board ensures the PROFINET network dialog data are converted into modbus rtu packages which are sent and received via the serial line. The diagram to keep in mind is as follows:

5�1� Profinet network connection and serial sub-net setup
UNDERSIDE VIEW VISTA FRONTALE
(*) GFW400-600
To connect the devices in a PROFINET network, use the ETH0 and/or ETH1 connectors of the integrated switch. To
connect the sub-net of the slaves unit, please refer to the diagram in the gure

80561A_MSW_GFW-Profinet_07-2018_EN
(*) GFW400-600
We recommend the use of a CAT5 Ethernet cable or above STP or UTP. The minimum distance between two Ethernet network nodes must be less than 100m

5�2� Rotary switch and dip switch selection
The hexadecimal rotary switches found on the GFW indicate the node address of the slave Modbus/RTU network that is acquired when the instrument is switched on.
The GFW is factory-set with the rotary switches in the
“0” position and it is the customer's task to put them in
the correct position, considering that ONLY the following
combinations apply for PROFINET:
Rotary X 10=0, Rotary X1=1 for node 1
Rotary X 10=0, Rotary X1=2 for node 2
Rotary X 10=0, Rotary X1=3 for node 3
Rotary X 10=0, Rotary X1=4 for node 4
The other rotary switch positions concern specic
functions.
The GFW conguration dip-switch, as described in manual /2/ in the chapter entitled “Description of Dip­Switches” is designed to dene the operating mode of
the instrument.
Dip “6”, in particular, when in the “ON” position, allows
the factory-set values to be restored upon “POWER
ON”.
AFTER RESTARTING THE INSTRUMENT WITH THE
FACTORY-SET PARAMETERS, REMEMBER TO SET
“6” TO THE “OFF” POSITION, SWITCH THE DEVICE
OFF AND BACK ON AGAIN.
DIP “7” MUST UNDER ALL CIRCUMSTANCES BE IN THE “OFF” POSITION BEFORE YOU SWITCH ON
THE DEVICE!
