Publication 1756-UM001E-EN-P - August 2002
Communicate with an RSView Project over a ControlNet™ Network
14-19
The following examples show how to use a buffer of INTs
EXAMPLE
Read integers from an RSView project
When
condition
turns on, reads 16-bit integer values (INTs) and stores them in
int_buffer
. Then the FAL instruction moves the values to
dint_array
. This converts the
values to 32-bit integers (DINTs), for use by other instructions in the ControlLogix
controller.
EXAMPLE
Write integers to an RSView project
When
condition
turns on, moves the values in
dint_array
to
int_buffer
. This converts the
values to 16-bit integers (INTs). Then the message instruction sends
int_buffer
to the
RSView project.
