Installation recommendations
Interface
The sensor complies with all requirements of the ProfiNET standard (IEC 61158), providing high-speed data transmission over an industrial Ethernet network. All measurements performed by the sensor are absolute and are transmitted at speeds of up to 100 Mbit/s.
The ProfiNET bus allows up to 256 devices to be connected within a single network, ensuring system flexibility and scalability. Various network topologies are supported, including star, ring, and line. Sensor parameters are loaded into the system using a GSDML file.
Sensor operating modes:
Real-Time (RT) mode:
- Provides data transmission with minimal latency.
- Suitable for applications that do not require strict synchronization.
Isochronous Real-Time (IRT) mode:
- Provides precise synchronization of devices within the network.
- Used in applications with high requirements for timing performance.
Multi-position measurement
OPERATING MODES |
Data exchange When measuring with multiple magnets, 1 byte of status data and 3 bytes of position data are transmitted per cycle. The status data byte contains: an error bit and the number of positions in the current measurement. |
 U401 – Measurements with one magnet (standard) U402 – Measurements with multiple magnets, 2–8 pcs Simultaneous measurements with up to 8 magnets, minimum distance between magnets 76 mm. |
