Page 2: Introduction
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. - Page 3 ● Port1 - Port 2 M12 4P Female D-coded connector connection M12 Female 4 poles D coded Pinout connector (Port1 – Port 2) ● Power Supply M12 4P Male A-coded connector connection M12 Male 4 poles A coded Pinout connector (Power Supply) We recommend the use of a CAT5 Ethernet cable or above STP or UTP.

Page 17: Example Of Plc Configuration
6. EXAMPLE OF PLC CONFIGURATION In the following some examples of integration of WPA-F/WRA-F into a PLC system are given, both for General Profile and Encoder Profile, both RT and IRT communication. TIA Portal is taken as an example. First of all the right GSDML file of device has to be installed into the catalog of TIA Portal: ●... - Page 18 If IRT communication is selected the respective flag in Isochronous mode page must be checked And the network topology must be arranged setting the Sync domain of the devices composing the network 80715_MAN_WPA-F_WRA-F_03-2021_ENG...
- Page 19 According to the loaded module/s it’s needed to select the cursor to measure inside Module parameters. Modul Sensor status does not have parameters to select. In module parameters of the main module (Slot 0) it’s possible to select parameterization for the whole device, as well as setting of offset for each cursor 80715_MAN_WPA-F_WRA-F_03-2021_ENG...
