The 

VARSHI

 command helps you use shared data over a peer-to-peer Ethernet connection with other 6K or Gem6K 

products. 

VARSHI

 can be used to assign the integer or binary 

VARSHO

 data to a 

VAR

 (numeric), 

VARI

 (integer), or 

VARB

 

(binary) variable, or to a virtual input brick (

IN

). You can also use 

VARSHI

 in a conditional statement, such as 

IF

, 

WAIT

, 

WHILE

, or 

UNTIL

.  

The diagram below shows the syntax requirements for assigning 

VARSHI

 data to a variable: 

<assignment> = <n>

Assignment options:

Variable number

Number of the source unit
(use this unit’s VARSHO

data)

Number of the VARSHO

variable from unit <n>

VAR (numeric variable)
VARI (integer variable)
VARB (binary variable)

<variable>n

I/O brick number.

The Implementation Process, beginning on page 

, identifies how to use the 

VARSHI

 command in 

context with the process of setting up the peer-to-peer Ethernet data sharing. 

Example: This example uses peer-to-peer communication with three 6K8 products. 

;****  This code is executed on Peer unit #1:  ************************** 
NTID1 

; This unit is the "primary unit" (unit #1) 

NTRATE100 

; Set the sharing rate to 100ms and enable this unit 

VARSHO1=1PE 

; Store axis #1 encoder position in shared output variable #1 

;************************************************************************* 
 

 

;****  This code is executed on unit #3:  ************************** 
NTID3 

; Set unit ID to 3 

NTRATE100 

; Set the sharing rate to 100ms and enable this unit 

VARSHO2=4PCEA 

; Store the captured encoder position of axis #4 in shared 
; output variable #2 

VARSHO1=3AS 

; Store axis #3's axis status (binary data) in shared  
; output variable #1
