E3NW-ECT EtherCAT Digital Sensor Communication Unit Operation Manual (E429)
• This object reads the blue detection level (incident light level) of the Sensor Amplifier with the unit
number specified by the index.
• This object reads the pattern of the detection level (incident light level) of the Sensor with the unit
number specified by the index.
* The reading cycle and data are as follows.
The light levels read in the initial 2 bits of the 1st and 2nd bytes and the 3rd and 4th bytes are
distinguished.

0000 hex Reads the amount of detection level (incident
light level) at the Sensor Amplifier in 1 ms.
Reads the input measurement value. (Before
scaling & zero reset)
0001 hex Reads the amount of detection level (incident
light level) at the Sensor Amplifier and the
amount of RGB incident light at a cycle of 1 ms.*
Reads the displayed measurement value. (After
scaling & zero reset)
