Parker Hannifin GEM6K manual

Program	After the connection is established, mapping has been set up, and polling enabled, the 6K starts
Interaction	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

if(VARI129 =

17)

;

Element

;

file 10

of the AB PLC

in file
