Command Descriptions and Data Formats
●
Continuous Read Detection Level
This command continuously reads the Detection Level (incident light level) of the
Sensor Amplifier Unit that corresponds to the specified unit number and output number.
This is not supported by explicit messages.
The data is given as the two’s complement of a 4-byte (8-digit) hexadecimal value.
●
Read Peak Detection Level
This command reads the Peak Detection Level (incident light level) of the Sensor
Amplifier Unit that corresponds to the specified unit number.
To read the peak detection level, you must select the input peak minimum value and
interrupted light bottom maximum value [P-b] for the Display Switch Setting.
The data is given as the two’s complement of a 4-byte (8-digit) hexadecimal value.
●
Read Bottom Detection Level
This command reads the Bottom Detection Level (incident light level) of the Sensor
Amplifier Unit that corresponds to the specified unit number.
To read the Bottom Detection Level, you must select the input peak minimum value and
interrupted light bottom maximum value [P-b] for the Display Switch Setting.
The data is given as the two’s complement of a 4-byte (8-digit) hexadecimal value.
●
Threshold Setting 1
This command reads or writes Threshold Value 1 of the Sensor Amplifier Unit that
corresponds to the specified unit number and output number.
Threshold Value 1 is the threshold value in normal detection mode or the low threshold
value in area detection mode.
The data is given as the two’s complement of a 4-byte (8-digit) hexadecimal value.
Do not execute any write instructions that exceed the allowable data range for each model.
