NTIO, \TIN, \TIO, VARB

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

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\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 ...
