10.8. Number of averaged values/time of averaging
This parameter specifies the number of source results to be averaged for deriv-
ing the output value or time of the averaging .
The use of averaging makes it possible to reduce the output noise and increase
the sensor resolution.
Averaging over a number of results does not affect the data update in the sensor
output buffer.
In case of time averaging, data in the output buffer are updated at a rate equal to
the averaging period.
Note.
Maximum parameters value is 127.
10.9. Factory parameters table
The sensors are supplied with the parameters shown in the table below:
Parameter Value
Time limit for integration 3200 (3,2 ms)
Sampling mode time
Sampling period 5000 (5 ms)
Point of zero Beginning of the range
Line AL operation mode 1
Time lock of the result 5 ms
Method of results averaging Over a number of results
Number of averaged values 1
The parameters are stored in nonvolatile memory of the sensor. Correct chang-
ing of the parameters is carried out by using the parameterization program supplied with
the sensor or a user program.
11. Description of RS232 and RS485 interfaces
11.1. RS232 port
The RS232 port ensures a ―point-to-point‖ connection and allows the sensor to
be connected directly to RS232 port of a computer or controller.
11.2. RS485 port
In accordance with the protocol accepted and hardware capability, the RS485
port makes it possible to connect up to 127 sensors to one data collection unit by a
common bus circuit.
11.3. Modes of data transfer
Through these serial interfaces measurement data can be obtained by two me-
thods:
by single requests (inquiries);
by automatic data streaming (stream).
11.4. Configuration parameters
11.4.1. Rate of data transfer through serial port
This parameter defines the rate of data transmission via the bit-serial interface in
increments of 2400 bit/s.
For example,
the parameter value equal to 4 gives the trans-
mission rate of 2400*4 = 9600 bit/s.
