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 defined 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 official PROFIBUS CONSORTIUM
and PROFINET International website (PI), http://www.profibus.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 defined as in ordination code E4/E6:
- E4 - Specific 2.2 - Stack 3.4.26.1 - Card ETH4 with Netx50
- E6 - Specific 2.3 - Stack 3.12.0.5 - Card ETH6 with Netx51
FEATURE NEW PROFINET (stack PROFINET specifica 2.3) COMPARED TO OLD E4 (stack PROFINET specifica
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
traffic equal to 32.5us instead of 1ms
