[ \IN ]
Network Digital Input Status
Type: Network; Assignment or Comparison Product Rev
Syntax: n\mIN<=Bbbbb> (see example below)
n\iIN.i (see example below)
Units: n = network server #
m = module #
i = digital input # on module “m” (for bit-select operation)
Range: n = 1-6
m = 0-7
j = 1-4
Default: n/a
Response: n/a
See Also: NTIO, \TIN, \TIO, VARB
6K 5.3
Use the \IN operand to assign an OPTO22 digital input value to a binary variable ( VARB ), or to make a comparison against a
binary or hexadecimal value.
Syntax: VARBx= n\mIN where “ n ” is the network server number of the OPTO22 unit and “ m ” is the I/O module number
(e.g., VARB16=2\0IN ). The \IN operand can also be used in an expression such as IF(2\3IN=b11Ø1) , or
IF(2\3IN=h7F) . To make a comparison against a binary value, place the letter b (b or B) in front of the value.
The binary value itself must only contain ones, zeros, or Xs (1, Ø, X, x). To make a comparison against a
hexadecimal value, place the letter h (h or H) in front of the value. The hexadecimal value itself must only
contain the letters A-F, or the numbers Ø-9.
Bit Select Operation: To address only one input value, instead of all the inputs, use the bit select (
. ) operator.
For example, VARB1=2\3IN.3 assigns the binary state of input 3 on module 3 of OPTO22 server 2 to binary
variable 1. In another example, WAIT(2\3IN.1=b1) tells the 6K to wait until input 1 on module 3 of OPTO22
server 2 is active.
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\0NTIO1 ; Server #2 (OPTO22), module #0 is a digital input module
2\1NTIO1 ; Server #2 (OPTO22), module #1 is a digital input module
WAIT(2\1IN.2=b1) ; Wait until input #2 of module #1 on Server #2 (OPTO22) is active
IF(2\0IN=bxx1) ; If input #3 of module 0 on Server #2 (OPTO22) is active ...
