The WPA-F/WRA-F is available with different Communication Profiles, according to ordering code:
● a standard IO profile, so called General Profile
● an Encoder Profile, compliant with v. 4.2 Class 4
Indipendently from profile the WPA-F/WRA-F is available with RT and IRT communication with min device interval up to 250 us (for
IRT only).
The Isochronous communication can be set inside the network tool (TIA Portal as an example), following the menus related to "Real
Time Settings"
With this Profile up to 16 cursors are detectable and measured by the device.
The device WPA-F / WRA-F offers different process data and different configuration for process data.
The process variables available are:
Position (32 bit signed), for each of the cursors installed. For resolution refer to configuration options.
31..0
Position
Velocity (32 bit signed), for each of the cursors installed. For resolution refer to configuration options.
31..0
Velocity
Status (8byte), composed as following:
Voltage supply measured by device: 16bit (unsigned), 1mV resolution, 200mV sensitivity
Nr. of cursors detected: 8bit, change continuously according to nr. of cursors effectively detected
Bitmask of cursors configured: (5 byte), fixed bitmask of cursors set during configuration

The device WPA-F/WRA-F provides different modules containing process data. These modules are selectable in the input modules
catalog:
● Position: this module contains the position data of one cursor
● Velocity: this module contains the velocity data of one cursor
● Position and Velocity: this module contains the data of position and velocity of one cursor
● All Positions: this module contains the data of position of all the detectable cursors (16)
● All Velocities: this module contains the data of velocity of all the detectable cursors (16)
● Sensor Status: this module contains the data of status of the device (see process data structure)
