Analog Output Functions and Operating Procedures Section 6-7
Writing Set Values Analog output set values are written to CIO words (n+1) to (n+4).
For the CIO word addresses, n = CIO 2000 + (unit number x 10).
Use MOV(021) or XFER(070) to write values in the user program.
Example 1 In this example, the set value from only one input is read. (The unit number is
0.)
Example 2 In this example, multiple set values are written. (The unit number is #0.)
Note If the set value has been written outside the specified range, an output setting
error will occur, and the value set by the output hold function will be output.
Starting and Stopping
Conversion To begin analog output conversion, turn ON the corresponding Conversion
Enable Bit (word n, bits 00 to 03) from the user’s program.
For the CIO word addresses, n = CIO 2000 + (unit number x 10).
The analog output when conversion is stopped will differ depending on the
output signal range setting and output hold setting. Refer to
Setting Outputs
and Signal Ranges on page 259 and 6-7-2 Output Hold Function .
Conversion will not begin under the following conditions even if the Conver-
sion Enable Bit is turned ON. Refer to
6-7-2 Output Hold Function .
1,2,3... 1. In adjustment mode, when something other than the output number is out-
put during adjustment.
2. When there is an output setting error.
Word Function Stored value
n+1 Output 1 set value 16-bit binary data
n+2 Output 2 set value
n+3 Output 3 set value
n+4 Output 4 set value
MOV (021)
D00001
2001
Input condition
The set value stored in D 00001
is written to CIO word 2001 (out-
put number 1).
XFER(070)
#0004
D00001
2001
Input condition
The set values stored in D 00001
to D 00004 are written to CIO words
2001 to 2004 (outputs 1 to 4).

Output 2 Output 1
Analog conversion is executed while
these bits are ON. When the bits are
turned OFF, the conversion is stopped
and the output data is held.
