Schneider's new development platform: UNITY do offer the capabilities of a small DCS system at reasonnable costs.
Worth to mention also a new era of ruggedized "open" controllers on industrial redundant Ethernet at even lower costs than PLCs complete with a powerfull development platform such as the MTL Instruments: M.O.S.T. system . and their Workbench tools. In addition, the MOST controllers do not require local stations nor control rooms nor costly protective buildings or installations . Eveything can live outside at temps from - 40°C to + 70°C ambiant...in standard junction boxes..!
