The FOUNDATION Fieldbus S-series H1 I/O card with integrated power supports two Ff H1 segments, each supporting up to 16 Ff devices. Each segment runs an independent scheduler that controls the order of execution of each function block configured on the segment. DeltaV control modules provide a function block structure that defines the order of execution of each block on the segment, making it easy for each loop to be sequenced for efficient loop execution.
