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
;*************************************************************************
;**** This code is executed on unit #2: **************************
NTID2 ; Set unit ID to 2
NTRATE100 ; Set the sharing rate to 100ms and enable this unit
VAR1=1VARSHI1 ; Load the value of unit #1's first shared data (1PE) into VAR1
WRITE"AXIS 1 AT POSITION" ; Report axis 1's current position (the value of VAR1)
WRVAR1
VAR2=8PCEA-3VARSHI2 ; Calculate offset position: Subtract synch unit #3's
; VARSHO2 (4PCEA) from the captured encoder position
; of axis #8 (8PCEA).
IF(VAR2>10000) ; If position offset by more than 10000 encoder counts
WRITE"AXIS 20 OUT OF POSITION"
NIF
VARB1=3VARSHI1 ; Get unit 3's VARSHO1 information (3AS)
IF(VARB1=B1) ; If axis 3 on unit #3 (axis #19) is in motion
WRITE"AXIS 19 IN MOTION"
NIF
