The position of the magnet along the waveguide is sent over the CANbus to the controller in so called Process Data Objects or PDOs. Micropulse transducers work with standard CANopen protocols as per CIA DS 301 and with the standard device profile as per DS5406. CANopen offers greater flexibility because of the large number of configurations options for the transducer. For example, the resolution is programmable for 5, 10, 20 or 100 µm - depending on your application. Alternatively you can select whether both position and velocity information are sent to your controller, cyclically or on-demand. And there's more: Up to 4 so-called software cams can be defined in the active measuring range. Each time the status of one of these cams changes, high-priority emergency messages are sent to the controller.
The Process Data Unit sends position and velocity information for the transducer to the controller via the PROFIBUS-DP. Micropulse transducers operate according to EN 50170 and support the PROFIBUS-DP encoder profile as well as multi-magnet operation. Micropulse transducers can be parameterized using the GSD file. The position resolution can be configured in 5 µm increments and the velocity resolution in increments of 0.1 mm/s. Working ranges and the null point can be configured individually for each magnet.
