It exposes a fixed object set: drive I/O terminals as AI, AO, BI and BO objects; references, measurements, fault history, ramp times and a parameter mailbox as Analog Values; and drive status and commands as Binary Values. A few output objects are only supported on some drives, noted in the descriptions.",
