Use the \OUT operand to assign an OPTO22 digital output value to a binary variable (VARB), or to make a comparison against a binary or hexadecimal value. The digital outputs are turned on and off with the \OUT command.

Syntax: VARBx=n\mOUT where “n” is the network server number of the OPTO22 unit and “m” is the I/O module number (e.g., VARB16=2\0OUT). The \OUT operand can also be used in an expression such as IF(2\3OUT=b11Ø1), or IF(2\3OUT=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 output value, instead of all the outputs, use the bit select (.) operator. For example, VARB1=2\3OUT.3 assigns the binary state of output 3 on module 3 of OPTO22 server 2 to binary variable 1. In another example, IF(2\3OUT.1=b1) evaluates true if output 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\3NTIO2	; Server #2 (OPTO22), module #3 is a digital output module
2\3OUT1001	; On Server #2, module #3, turn on Outputs #1 and #4 and turn off
VARB9=2\3OUT	; Outputs #2 and #3
	; Assign the binary state of all digital outputs on module #3 of

;Server #2 to binary variable #9 (VARB9). As a result, the value

;of VARB9 will be 1001_0000_0000_0000_0000_0000_0000_0000.
