PLC User's Manual - Analog Control Edition
FX3U-4DA (4-channel Analog Output)
*1. If power failure occurs, the EEPROM will retain the data.
*2. Specify the use of the upper/lower limit function for each channel setting one of hex code 0 to 2 in
each digit.
*3. Use b0 to b1.
*4. Specify the use of the corrective function by load resistance for each channel setting a hex code 0 or
1 in each digit.
*5. Use b0 to b2.
