B Monitoring Incident Light Levels Of E3X-Da6-P Sensors - Omron E3X-DRT21 Operation Manual

When E3X-DA6-P Sensors are used, the incident light levels for Sensor output ON and Sensor output OFF can
be monitored along with standard incident light levels. The following table shows the typical values for ON/OFF
incident light levels.
Type
ON incident light level
OFF incident light level
Details on ON/OFF incident light level monitoring are provided below.
Note When incident light levels are read using standard incident light level monitoring through communica-
tions, the communications can cause a delay. When the Sensors ON/OFF switching interval is short, this
delay can cause only Sensor OFF data to be read, for example, resulting in the inability to read ON data
(in the same way, it is possible that only ON data is read, and OFF data cannot be read). When E3X-
DA6-P Sensors are used, in addition to standard incident light levels, incident light levels for Sensor out-
put ON and Sensor output OFF can also be monitored.
