6. Sensor function

Analog

The analog output can be set via RS485, and the sensor can work in 8 modes. The specific reference is as follows:

Step 1: Connect to the host computer through the serial port debugging assistant or modus debugging assistant.

The second step is to set a near point reference distance point.

Step 3, set a far point reference point

The fourth step is to set the output voltage or current of the near-point reference point.

Step 5: Set the output voltage or current of the remote reference point.

The sixth step is to set the analog output as the switch characteristic selection.

The seventh step is to set the analog output as a linear output or switch output option.

Step 8, reset the sensor to make the new parameters take effect.

8 working modes of the sensor.

1: Open window mode by default

2: The window mode is closed by default

3: Single point mode is turned on by default

4: Single point mode is turned off by default

5: Single-point hysteresis mode is turned on by default

6: Single-point hysteresis mode is turned off by default

7: The presence or absence detection mode is turned on by default

8: The presence or absence detection mode is turned off by default

485 output data

485 output data is in MODBUS-RTU format. Refer to the software instruction manual for details.
