VISY-Power Interface

The communications interface between the sensor and a higher-level system (master)

For the sending of commands to the sensor, the VPI supports two protocols*.
The response is Assigned and forwarded to the individual sensor terminals.

  • 8 intrinsically safe sensor terminals per VPI
  • Connection of max. 32 VPIs in parallel possible = 256 sensor terminals
  • One sensor terminal can support the connection of up to four sensors
  • Passive communication via RS485
