Abstract
A reflex I/O card for an industrial controller receives enabling inputs from the executed control program and triggering inputs from an industrial process to provide outputs at a fixed delay in time or portion of a machine cycle after the inputs through dedicated hardware thus avoiding transmission delays and processing delays associated with the communication of information to a central processor and the execution of the control program.
