Abstract
The two levels of programming complexity include a high level and an expert level. The command set on the high level includes a plurality of commands which comprise sequences of more detailed commands from the expert level. The expert level commands comprise single actions or operations, or small groups of operations, to be performed by the electromechanical devices, such as valve openings or closures. User access privileges are definable by a system manager to restrict different classes of users to one or more of the levels of complexity.
