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: OPTO22 is Network Server #2

Example:	; Identify network server #2 as an OPTO22 unit at IP address
2NTIP2,172,54,125,34
2NTCONN1	; 172.54.125.34
	; 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
VAR23=2\4ANO.1	; +4.8 VDC
	; 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.

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
