Network Analog Input Voltage Status
Type:
Network; Assignment or Comparison
Product Rev
Syntax:
n\mANI.i (see example below)
Units:
n = network server #
m = module #
i = analog input # on module “m”
Range:
n = 1-6
m = 0-7
j = 1-2
Default:
n/a
Response:
n/a

Use the
\ANI
operand to assign the voltage level of an OPTO22 analog input to a real variable (
VAR
), or to make a
comparison against another value.
Syntax:
VARx=n\mANI.i
where “
n
” is the network server number of the OPTO22 unit, “
m
” is the I/O module number,
and “
i
” is the input/channel number on the module (e.g.,
VAR3=2\1ANI.1
assigns the voltage at analog input 1
on module 1 of OPTO22 server 2 to
VAR3
). The
\ANI
operand can also be used in a condition expression such as
IF(2\3ANI.1>=2.0)
or
WAIT(2\4ANI.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
2\0IN.3 2\3OUT.2 2\5ANO.1 2\7ANI.2
Example:
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\6NTIO3 ; Server #2 (OPTO22), module #6 is an analog input module
2\7NTIO3 ; Server #2 (OPTO22), module #7 is an analog input module
WAIT(2\6ANI.1<=+1.5) ; Wait until the voltage at analog input #1 of module #6 on
; Server #2 (OPTO22) is less than or equal to +1.5VDC
IF(2\7ANI.2>+2.4) ; If the voltage at analog input #2 of module 7 on Server #2
; (OPTO22) is greater than +2.4 VDC ...
