Read integers from an RSView project
EXAMPLE
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.
