3U

-4DA (4-channel Analog Output)

This chapter describes the minimum programming necessary for analog output by the FX

3U

-4DA. 

Follow the procedure below to confirm that correct analog values can be output.

Unit numbers from 0 to 7 will be assigned to the special function units/blocks starting from the left.
When the units/blocks are connected to the FX

3UC

-32MT-LT(-2) PLC, the unit numbers from 1 to 7

are assigned. Check the unit number assigned to the FX

3U

-4DA.

Depending on the analog signal generator to be connected, set the output mode (BFM #0) for each
channel.

Use hexadecimal numbers for output mode setting. Set the corresponding channel digit to the
output mode setting value specified in the following table:

→ For a detailed description of the standard output characteristics, refer to Section 2.4.

→ For a detailed description of the output mode (BFM #0), refer to Subsection 5.4.1.
