11.7.7. Notes
·
All values are given in binary form.
·
Base distance and range are given in millimeters.
·
The value of the result transmitted by a sensor (D) is so normalized that 4000h
(16384) corresponds to a full range of the sensor (S in mm), therefore, the result in
millimeters is obtained by the following formula:
X=D*S/4000h (mm) (1)
·
On special request (05h), the current result can be latched in the output buffer
where it will be stored unchanged up to the moment of arrival of request for data
transfer. This request can be sent simultaneously to all sensors in the net in the
broadcast mode in order to synchronize data pickup from all sensors.
·
When working with the parameters, it should be borne in mind that when power is
OFF the parameter values are stored in nonvolatile FLASH-memory of the
sensor. When power is ON, the parameter values are read out to RAM of the
sensor. In order to retain these changes for the next power-up state, a special
command for saving current parameter values in the FLASH-memory (04h) must
be run.
·
Parameters with the size of more than one byte should be saved starting from the
high-order byte and finishing with the low-order byte.
·
ATTENTION!
It is not recommended to configure the network addresses of the
sensors connected to the network using the "common bus" scheme (RS485).
