| Digital, parallel The distance is issued in the form of an 8-bit data word in parallel on three lines. Digital, serial These ultrasonic sensors can be parameterised via a bi-directional RS 232 interface, or issue the measured distance in serial form. Outputs: - Absolute/relative distance in 8- or 12-bit resolution - Switching states - Object in measuring window (A1, A2 or NDE*, FDE*) - Object in sensing range -etc. * NDE = Near Distance of Evaluaton FDE = Far Distance of Evaluation Parameterisation - Switching distances A1, A2 - Measuring window (NDE, FDE) - R ising/falling ramp of analogue output - N ormally open/normally closed function The parameterisation can be performed with the Ultra 2001 service program or a terminal program and individual commands. A list of valid commands is contained in the individual sensor data sheets. Digital, serial/parallel These ultrasonic sensor function in the same way as those with the serial interface, but also feature an 8-bit parallel output for the measured distance. The parallel interface is pa-rameterisable via RS 232 using the Ultra 2001 application. |
