4. Programming
This chapter describes how to create programs that can output the analog data using the 1DA-BD.
4.1 Writing of D/A Conversion Data
1) The input digital data will be converted into analog data and then output to the terminals.
2) If data is stored in the special devices, the averaging time can be set, and the output mode can be
specified.
3) In the FX
3G Series PLC (40-point or 60-point type), special auxiliary relays (10 points) and special data
registers (10 points) are assigned to each analog expansion board, board A and B connected to option
connector 1 and 2 respectively, in that order.
In the FX
3G Series PLC (14-point or 24-point type) and FX3S Series PLC, special auxiliary relays (10
points) and special data registers (10 points) are assigned.
→ For a detailed description of special device assignment, refer to Section 4.2.

The analog expansion board connected to option connector 1 is regarded as the "board A", and the analog
expansion board connected to option connector 2 is regarded as the "board B".
*1. Board B is not available in the FX
3G Series PLC (14-point and 24-point type).
