Detailed Explanation of Functions
Vision Sensor Dedicated Commands and Status Variables
9-110
(5) C_NVS1 - C_NVS8
[Function]
Stores the data recognized by the vision sensor in text string data format.
In an NVPST command or NVIN command, when a <type> of "2" or "3" or “6” or “7” is specified, the data in
the cell range specified with <Start cell> - <End cell> is stored.
Example:
In the above vision program, when "J95" and "Q98" are specified in the <Start cell> and <End cell> of the
NVPST command or NVIN command, the value of C_NVS1() becomes the following values.

[Array element count]: (30.10)
It is possible to acquire 30 lines and 10 columns of information from all the cell information in the vision
program.
[Sample sentence]
10 DIM MSCORE(100) 'Declares the variable for storing scores.
100 IF M_NVOPEN(1)<>1 THEN
' When logon has not been completed for vision sensor number 1
110 NVOPEN “COM2:” AS #1
' Connects with the vision sensor connected to COM2 and sets its
number as number 1.
120 ENDIF
130 WAIT M_NVOPEN(1)=1
' Connects with vision sensor number 1 and waits for logon to be
completed.
140 NVPST #1,”TEST”,”E76”,”J95”,”Q98”,3,10
'Starts the "Test" program, receives the recognition count from the E76 cell and the recognition results from
cells J95 through Q98, and stores this in C_NVS1(1,1) - and M_NVS1(1,1) - .
150 MVCNT=M_NVNUM(1)
'Acquires the number of pieces of work recognized by the vision sensor.

310 MSCORE(MCNT1)=VAL(C_NVS1(MCNT1+1,MCNT2)) ' Stores the score for the recognized work into

340 IF MSCORE(MCNT)>90 THEN MOK=MOK+1 'If the score is 90 points or higher, adds 1 to MOK.
350 NEXT MCNT
