i = analog output # on module “m”
Range:
n = 1-6
m = 0-7
j = 1-2
m = 0-7
j = 1-2
Default:
n/a
Response:
n/a

Use the
\ANO
operand to assign the voltage level of an OPTO22 analog output to a real variable (
VAR
), or to make a
comparison against another value. The voltage at the analog outputs is controlled with the
\ANO
command.
Syntax:
VARx=
n\mANO.i
where “
n
” is the network server number of the OPTO22 unit, “
m
” is the I/O module number,
and “
i
” is the output/channel number on the module (e.g.,
VAR3=2\5ANO.1
assigns the voltage at analog input 1
on module 5 of OPTO22 server 2 to
VAR3
). The
\ANO
operand can also be used in a condition expression such as
IF(2\3ANO.1>=2.0)
or
WAIT(2\4ANO.1<=1.5)
.
The controller addresses the OPTO22 I/O locations as follows:
Each I/O bit is addressed by its location on a specific module. (NOTE: I/O points are not addressed by an absolute
32-bit location on the OPTO22.) Digital input and output modules have four I/O points, or channels, and are numbered
1-4. Analog input and output modules have two I/O points, or channels, and are numbered 1-2.

Example:
2NTIP2,172,54,125,34 ; Identify network server #2 as an OPTO22 unit at IP address
2NTIP2,172,54,125,34 ; Identify network server #2 as an OPTO22 unit at IP address
; 172.54.125.34
2NTCONN1
; Attempt a connection to network server #2 (OPTO22 unit)
2\4NTIO4
; Server #2 (OPTO22), module #4 is an analog output module
2\4ANO.1=4.8
; On Server #3, module #4, set the voltage on analog output #1 to
; +4.8 VDC
; +4.8 VDC
VAR23=2\4ANO.1
; Assign the voltage at analog output #1 on module #4 of Server #2
; to real variable #23 (VAR23). Based on the preceding command,
; the value should be +4.80.
; to real variable #23 (VAR23). Based on the preceding command,
; the value should be +4.80.
WAIT(2\4ANO.2<=+1.5) ; Wait until the voltage at analog output #1 of module #4 on
; Server #2 is less than or equal to +1.5VDC
