Program 
Interaction 

After the connection is established, mapping has been set up, and polling enabled, the 6K starts 
exchanging data automatically with the PLC. Here is how to: 

• 

Write a binary variable to the PLC: Write a value to one of the 

VARB

 variables in the 

NTMPWB

 mapping. The new data is written to the binary file during the next poll. 

• 

Write an integer variable to the PLC: Write a value to one of the 

VARI

 variables in the 

NTMPWI

 mapping. The new data is written to the integer file during the next poll. 

• 

Read a binary variable from the PLC: The 

VARB

 variables in the 

NTMPRB

 mapping 

correspond to the values in the binary file in the PLC.  

• 

Read an integer variable from the PLC: The 

VARI

 variables in the 

NTMPRI

 mapping 

correspond to the values in the integer file in the PLC. 

Example 

VARB100 = HAB79  ; Element 3 in file 10 of the AB PLC will be equal to VARB100 
if(VARB106 = B1111111111111111)    ; VARB106 will be equal to variable 7 in  
                                   ; file 10 of the AB PLC  
if(VARI129 = 17)  ; Element 6 in file 20 of the AB PLC will be equal to VARI129 
VARI121 = 17 

; Element 4 in file 20 of the AB PLC will be equal to VARI121
