Read the detection level/read the detection level on detected (ON)/
read the detection level on undetected (OFF)
These commands read the detection level of the sensor with the unit No. specified with
the Instance ID.
Those data is shown in hexadecimal as a four-digit value (two bytes).
If the data is negative, the 12th bit is 1 (on).
Read Detection level on Detected (ON) and Read Detection level on Undetected (OFF)
can read the detection level only when the display switching settings are peak on
detected and bottom on undetected.
Also, its data range is between F831Hex (complement of 2) and 0FA0Hex.
●
Read detection level + ON/OFF output
It reads the detection level of the sensor with the unit No. specified with the Instance ID.
The data is shown in hexadecimal as a four-digit value (two bytes).
If the data is negative, the 12th bit is 1 (on).
