*1. When any of the following Sensors is connected, two words are allocated per Sensor and each Sensor is counted as
       two Sensors for the number of connected Sensors.
       E3X-DA[]-S ([]: 7/9), E3X-DA[]TW-S ([]: 6/8), E3X-MDA[] ([]: 6/8), E3C-LDA[] ([]: 6/8), E2C-EDA[] ([]: 6/8)
*2. Communications is possible for the ON/OFF output data from 13 Units. One word is allocated as the input area in the
       Master.
*3. Communications is possible for the ON/OFF output data from 16 Units and the number of connected Sensors. Two
       word sare allocated as the output area in the Master.
*4. Communications is possible for the ON/OFF output data from 16 Units, the number of connected Sensors, and the
       detection levels for the connected Sensors.
       Two words are allocated as the input area and one word is allocated for the number of connected Sensors in the
       Master.
*5. Connection cannot be performed if the response speed of the Sensor is set to super-high-speed mode.
*6. This does not include the current supplied to the Sensor.
