Command Descriptions and Data Formats
●
Dummy Sensor Response Setting
This command registers a Dummy Sensor.
If a Dummy Sensor is registered as Unit 1 (i.e., if bit 00 is 1), the actual first Unit (i.e.,
the leftmost Sensor Amplifier Unit) will be Unit 2.
You must restart the Sensor Communications Unit for any changes to the Dummy
Sensor Settings to take affect.
This setting cannot be changed via I/O commands in I/O Mode 2.
●
Dummy Sensor Response Setting
You can specify the response to return when an explicit message is sent to a Dummy
Sensor.
If you select to return a normal completion instead of an error completion, 0000 will be
returned for any read command sent to a Dummy Sensor.
This setting cannot be changed via I/O commands in I/O Mode 2.
●
Sensor Model
This command reads the model of the Sensor Amplifier Unit that corresponds to the
specified unit number.
●
Read Detection Level
This command reads the detection level (incident light level) of the Sensor Amplifier
Unit that corresponds to the specified unit number and output number.
The data is given as the two’s complement of a 4-byte (8-digit) hexadecimal value.
