WPA-F / WRA-F magnetostrictive transducer implements Profinet IO communication.
Profinet is a digital communication standard developed and maintained by PI (Profibus and Profinet International).
The digital communication allows the transfer of data between the Device (the WPA-F/WRA-F transducer) and the Master (PLC)
through a network.
These data are:
● Process data, such as position, speed, status of the device
● Acyclic data, as parameterization, statistic, diagnostic data
Profinet standard provides a descriptor file called GSDML (General Station Description based on XML format).
This file allows a clear identification of the device and comprehension of data provided and exchanged.
Please refer to Gefran website for the download of GSDML files.
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/.
The system must be used only in accordance with the required protection level.
The sensor must be protected against accidental knocks and used in accordance with the instrument's ambient characteristics.
The sensors must be powered with non-distributed networks.
The transducer must be grounded (normally through the machine body or equipment it is installed on).
Connect cables shielding to ground at cabinet side (control equipment or PLC).
To prevent interference, separate the power cables from signal cables.
The WPA-F/WRA-F transducer provides 3 connectors on its head:
● 2x M12 Female 4 poles D coded for Fieldbus connection (A-B in the image below)
● 1x M12 Male 4 poles A coded for bringing Power Supply to the device (C in the image below)
