Abstract
A system and method for enabling deterministic or time-triggered data exchange between a first graphical program and a second graphical program. A first variable is assigned to a first time slot in a network cycle. A first graphical program may be configured to write data to the first variable. A second graphical program may be configured to read data from the first variable. The first graphical program may be executed on a first computer system, where executing the first graphical program comprises writing data to the first variable. Writing data to the first variable may cause the data to be delivered over a network to a second computer system when the first time slot occurs. The second graphical program may be executed on the second computer system, where executing the second graphical program comprises reading from the first variable the data sent from the first computer system.
