Control modules and equipment modules can use the state-driven algorithm. A state-driven algorithm is an appropriate control strategy for simple equipment, device, and parameter manipulation where there are no complex equipment interlocks or timing issues. To create a state-driven module, create a new module, specify that it uses a state-driven algorithm, and specify a named set. The system creates composite blocks based on each of the named set states and an underlying SFC that manages the execution of the state-driven module. Named sets used for state modules can contain as many as 240 named states. You configure items that define how state changes drive specific contained module parameters. The following graphic shows the structure of a module based on a state-driven algorithm.
